LGP Equipment Rentals proudly provides Southern California with construction equipment rentals, supplies, tools and safety equipment. Owner, Luis Gutierrez started out with just one piece of equipment for rent, a cement mixer and now has an inventory of close to 300 units. The company has been family owned and operated by Luis and Lydia Gutierrez since 1996. Their rental list includes skid steers, air compressors, painting and gardening implements, drills, jackhammers, scaffolding and a whole lot more. LGP has built a solid reputation throughout the years by providing their customers with professional service and low prices. They are conveniently located in South Gate and recently took delivery of a brand new John Deere CT315 track loader from Coastline Equipment.

Luis Gutierrez comments, “We’re very pleased with our new John Deere CT315 from Coastline. It’s been a great addition to our rental fleet and our customers like it so much, that we have a hard time keeping it in the yard. The heavy-duty construction of this track loader, makes for a very long machine life and more up time, two very important factors for a rental equipment company. Another important feature that we appreciate is the versatility of the machine, including the tremendous variety of attachments that our clients can utilize. In addition, we appreciate the ease of operation and transport.”

Luis adds, “Coastline Equipment has been great to work with and I have been nothing but satisfied with their sales, parts and service departments. The Long Beach branch is located nearby, which is very convenient for parts or service.

Coastline’s sales representative, Andrew Brown has been easy to work with and we certainly appreciate his terrific follow-up and support. We are definitely going back to Coastline Equipment for our next machinery purchase.”

Kiewit Infrastructure West Co., a subsidiary of Kiewit Corporation, is the design-builder for the I-405 Sepulveda Pass Widening Project, which when completed will add 10 new miles of HOV lane, from the Santa Monica (10 Freeway) to the Ventura (101 Freeway). Kiewit will also be realigning existing on- and off-ramps, removing and replacing three bridge structures, widening 23 additional bridges and ramps, constructing 18 miles of retaining and sound walls, widening freeways and performing road improvements on adjacent City streets, all for just a little over $1 billion dollars. They began the anticipated four-year long construction phase in the second quarter of 2010 and are scheduled for completion by summer 2013.

A very small part of this overall behemoth project called for the demolition of the Mulholland Drive overpass. Normally, taking down a simple three-span box girder bridge should be fairly cut and dry.

However, in this case it required the closure of the busiest north-south freeway connection in Los Angeles, over a typically busy summer weekend. We're talking about the 405-freeway between the Valley and the Westside, where some 500,000 vehicles travel each day.

Transportation officials from the city, county and state did a great job steering drivers away from anticipated trouble spots, however a 53 hour shutdown could have possibly brought the most dire of

consequences, even “Carmageddon”.

Only time would tell, and all that was left to do was plan to the best of their ability.

Interestingly, it was Kiewit that built the Mulholland overpass more than 50 years ago and it is only fitting that they be the one to take it down and replace it with a 10 foot wider more efficient structure, designed to the latest seismic standards. Kiewit Infrastructure West worked for more than a year developing a timeline for the more than 2-day demolition process, even to the point of breaking work activity down into 15-minute

increments. The plan was thoroughly reviewed by their project partners, Caltrans and Los Angeles County Metropolitan Transportation Authority (Metro), and deemed to be the best possible strategy. As part of their line of attack, they called on Penhall Corporation and their 54-years of expertise to demolish the southern half of the Mulholland overpass. Penhall Corporation in turn called on National Demolition Contractors and their fleet of specialized Caterpillar demolition equipment and attachments for assistance. Frank Sahagun is the Bid

Administrator for National Demolition Contractors and he comments, “It was a great experience for National to work with a company like Penhall that has been a leader in our industry for so many years. They were a very coordinated group of individuals, extremely knowledgeable and highly motivated. We were also very impressed with their emphasis on safety and how well they look out for their employees. I believe this project was a great way for our firms to be introduced to one another and it helped solidify NDC as a major player in the industry.”

National Demolition Contractors arrived at the jobsite Friday July 16th at 2:00 PM for an initial review of the job and safety meeting. Arrangements had already been made for dirt trucks to come in and lay down a 4 ft. high pad spanning the entire width and length of the bridge. The dirt pad would serve as a cushion for falling debris, as well as protect the freeway itself during the demolition process.

The actual demolition portion of the bridge did not commence until about 3:00 AM the following morning, when National Demolition operators met once again for a walk through and yet another safety meeting with Penhall and Kiewit. Penhall Corporation began the demo by saw cutting sections of the bridge deck, followed by excavators readily equipped with pulverizer attachments. In addition, they had another high reach excavator with a pulverizer attachment working at the bottom of the bridge, followed

by National Demolition's Caterpillar 330D ultra high reach demolition hydraulic excavator and UB Pulverizer Shear attachment. The 330D was used to go in and break up the remaining concrete, while shearing the rebar at the same time. Frank Sahagun further explains, “We knew what we were up against, but the size 18 rebar was 2 1/2 inches thick and I can't say that I was not a little concerned about being able to quickly get through it all. If this failed, the only option would be to torch cut the rebar, adding many man hours, as well as putting workers at risk. It only took one pass to see that the rebar was no match for our UB Pulverizer Shear attachment. Not to be too

cliché but it really did go through the congestion worthy of the rebar like butter. We are very proud “Carmageddon” billing.

Written By: Brian Hoover Recycling is no longer just a nice catch phrase or even the right thing to do. It is the law and an absolute requirement in many cities and counties here in California. From rubber tires and drywall to bottles and cans and of course asphalt and concrete, recycling is making a visible difference to our environment. What used to take up valuable space in our landfills is now being put back to use in our everyday infrastructure, like roads and building sites.

Construction and demolition waste materials make up about 22 percent of California’s disposed waste stream, or to put it another way, around 8.7 million tons each year. In March 1995, the City of Los Angeles passed a motion requiring that road base in all city projects include crushed miscellaneous base (CMB) with 100 percent recycled asphalt concrete, except when site conditions or standards require another specification. A prime example of recycling done right can be clearly seen by looking at the benefits from the Interstate 5 Improvement project in Anaheim, California, where all of the aggregate used on the job came from recycled concrete and asphalt. The six

year project called for 800,000 tons of recycled aggregate, which in the end saved Caltrans approximately $5 million by not having to transport virgin material from a quarry.

So, I think that it is safe to say that it is generally accepted by most all contractors, cities, counties and other government agencies that recycling is a positive alternative to landfills and in most cases is also less expensive. In addition contractors can receive LEEDS (Leadership in Energy and Environmental Design) credits for 100% of the material that they drop off at a recycling station. Skipping transfer stations and going directly to the recycling yard can also save you the contractor money, by simply bypassing the middleman.

There are recycling yards located up and down the great state of California, but for the purpose of this article we are going to focus on one of the newest recycling companies to enter the fray. Greenstone Materials, Inc. was established by Rich and his wife Kristen Holt In July of 2010, after he purchased an already permitted facility in Perris, California.

Materials, Rich Holt explains, “For nearly a dozen years I have worked as a general engineering contractor, specializing in demolition, grading and other earthwork as R.B. Holt, Inc. During this time I became quite fascinated with just about every aspect of the construction recycling and crushing business. I have a true appreciation and respect for whole cycle, where all material that comes in then goes back out to be reused on another construction project. So, last summer I was very fortunate to have the opportunity to purchase a permitted crushing facility and to even inherit many of the fine people that worked there.

In March 2011, Greenstone Materials opened their second location in San Juan Capistrano. “There are several other organizations that are very good at this and have led the industry for years. We are grateful to be part of this whole green recycle industry and to be able to have the opportunity to see so much valuable material being put back to use in our infrastructure, instead of buried in a landfill.”

Greenstone Materials, Inc. accepts concrete, asphalt, rock and block. All incoming material must be clean of all deleterious material including but not limited to material

like: brick, grass, roots, trash, asbestos pipe or other hazardous materials. Their finished products are put back to use by paving contractors, pipeline contractors and municipalities on Caltrans projects and for developers, cities and counties. Their recycled products include: Class II/CMB aggregate base material, SE 40+ fill sand, 3/4”” to 1” crushed rock, 3/8” pea gravel and other custom products. Greenstone Materials, Inc.’s San Juan Capistrano plant also works directly with a local rock quarry, allowing them to offer natural aggregate and natural sand to their customers as well. Everything they sell is tested to meet or exceed Caltrans and ASTM specifications. Rich Holt continues, “I began my own demolition business in 1999 and it has taught me just how much waste material like concrete and asphalt is really out there. Concrete and asphalt are the heaviest components aside from dirt in construction projects. Over the past few years we have been performing more and more onsite mobile crushing for our contractor customers. We own a new 2010 Terex/Cedarapids Jaw/Cone Crushing plant that we transport for use between our Perris and San Juan Capistrano operations.

The entire plant can be taken down, transported and set back up at one of our yards or at a customer’s job site in just about a day and a half. I think the fact that we are so mobile is what sets us apart in this industry and we have been kept quite busy because of it.”

Greenstone Materials purchased their Terex Cedarapids Jaw/Cone Crusher from Spaulding Equipment Company who also has a location in Perris, California. Rich Holt comments, “Startup costs in this type of business can be staggering, but Spaulding Equipment really helped us out with a great lease to own purchase option. As a matter of fact we just recently converted our plant to a purchase and are looking at adding a second plant in the near future.”

Obviously, getting into this kind of business is no walk in the park. Not just the financial end, but also on the permitting side of things as well. It can take 3 years or longer to procure the proper permits and then you still have to set up your facility according to proper and legal procedures. It is all very capital intensive and that is why Rich Holt was so happy to purchase the turnkey opportunity in Perris. In San Juan Capistrano, however it

was a different story. Rich explains, “It took us a long time to get up and running on the second site. We hired consultants, engineers and geologists and others who put in many hours of work to make it finally happen. We then had to purchase new equipment for loading the plant and moving and processing material. We turned to Quinn Cat for our heavy equipment needs. I have bought around 18 pieces of machinery from them over the years and I know I can count on them. Recently we acquired a new Cat 980H wheel loader and a new 330D excavator. We also own and operate several other late model Caterpillar machines at both locations. I have over a dozen-year relationship with our Quinn Cat sales representative, Jeff Liebl. He is not just my salesman, but also a close personal friend. Caterpillar equipment is the best in the world and you can get parts and service anytime and anywhere. We use the Cat excavators to process the incoming material into crushable size. This requires the use of multiple attachments including a hydraulic pulverizer, an 8,500 foot pound hydraulic breaker and a thumb bucket. For this, we turn to UB Equipment and Charles Min. I also have a long-term relationship with

Charles Min and he has a great product that holds up and does what it is advertised to do. I have purchased 4 or 5 hydraulic breakers from them in the past as well as shears.”

The equipment you use in the Demolition and Recycling business is certainly important, but so are the people that run the equipment, as well as the office staff that keep everything running smoothly each day. Rich Holt elaborates, “I have a wonderful crew and when we started this business and purchased the permitted crushing site, four key employees from the previous owner came with it and I couldn’t be more blessed to have them here today. They compliment everything that I am trying to do. I am a young and hungry guy with 30 to 40 years left in this business, and it is comforting to know that each of our team members are also hungry and eager to be their best. We also have the world’s best general manager by the name of Billy Yeager. Billy and the rest of our team know the crushing business and are a pleasure to work with. Together we are all about offering great products that are competitively priced

with superior service to back it up. I am very passionate about this business and Greenstone Materials is here to stay. I look forward to the future and meeting new people to share the benefits of the crushing and recycling industry.”

It seems like Greenstone Materials, Inc. is just getting started and according to Rich, they are looking at adding a 3rd and 4th yard when the timing is right. Their onsite crushing services are available throughout the state of California and they will deliver material anywhere with their fleet of trucks. Rich concludes, “We are here for the customer… keeping our clientele satisfied and their jobs running smoothly is what we strive for. We have friendly, construction-minded people that are eager to serve your needs.”

Mamco Construction is a family owned and operated enterprise, with Marwan Alabbasi serving as the Founder and President since its inception in 2006. After graduating from the University of Southern California in 1983, with a Bachelor's Degree in Civil Engineering, Marwan went on to gain more than 20 years experience in the civil engineering field and another 10 years in the construction field. Today he is a registered Civil Engineer in the State of California and holds a type “A” and “B” contractors license. All of this hard work and determination has led Marwan to a place in life where he is fortunate to bring his entire

family together and successfully operate a general engineering construction company here in Southern California.

This is certainly no easy task in times like these and Marwan Alabbasi relies on his wife Elizabeth to manage all of the day-to-day operations of the family business. Elizabeth has a Bachelor's Degree in Business and more than 10 years experience in managing and operating a variety of businesses. Marwan's two sons also work full time for the company, with Rumzi Alabbasi serving as the Vice President and his brother, Rami Alabbasi, who serves as the company's General Superintendent.

In 2006, when the company was just starting out, Mamco worked primarily on their own private and retail development type projects.

When everything began to slow down in 2008, they were kept busy with work provided by other development companies. By 2009, the decision was made to make the move to public works projects and this has kept them quite busy to date. Now, Mamco specializes in pipeline and underground utility work, some dry utilities, in addition to road work including: concrete and asphalt paving, curb and gutter, as well as grading and excavating.

Today, with more than 65 employees, Mamco has shown

tremendous growth by working primarily throughout the Inland Empire and the rest of Riverside County and at times in Orange and LA Counties.

Currently, Mamco Construction is installing 5,000 lineal feet of reclaimed water line for the Rancho California Water District. This project began in early May of 2011 and was completed in the middle of July. The approximately $650,000 project required Mamco to install 8” PVC from Diaz Road to Remmington Road in Temecula, California. This new line will serve as an interconnect which services the local industrial and commercial properties. Rumzi Alabbasi comments, “This job was fairly straight forward with the exception of the overall high ground water

table that we had to deal with. The water would raise to over 3 feet in some places, however we were able to easily manage this through standard pumping and diversion techniques.”

Most of the work that Mamco and other general engineering contractors face each day is obviously not too overwhelmingly exciting. But when a job comes along where a contractor can self perform nearly every aspect of the project, it is definitely much more satisfying. Rumzi Alabbasi explains, “We were recently awarded Phase I and II for the Fontana Civic Center Campus Parking Project, where we are completely reconstructing the parking lot for the City Hall and the Fontana Police Department. We are self performing every aspect of

this job except for striping and fencing; all the way from the landscaping, lighting, security cameras to the new asphalt pavement, sidewalks, curbs and gutters. This project began with the removal of the approximately 200,000 square feet of existing AC pavement, and another 1,000 cubic yards of concrete sidewalks, curbs and gutters, which we hauled off to local recycling facilities. It was necessary to break each phase into segments or portions of parking lot, so as to allow parking access at all times. This has been challenging at times, with all of the traffic from both city employees and the public, however our guys have done a great job and we are right on schedule to finish in mid-August.”

Mamco Construction & Development working on Phase II of the Fontana Civic Center Campus Parking Lot Project.

The parking needs in the Civic Center Campus area have increased over the years as a result of the construction of the new Lewis Library, Center State Theater, and the proposed Police Department expansion. By the end of this project, an additional 250 parking stalls will be available for use by the City staff and general public. Overall traffic accessibility will also be enhanced with the new alignment of Wheeler Avenue and Library Way. With a price tag of nearly $2.2 million, this job called for much more than just additional parking stalls. For instance, it was also necessary to relocate some of the existing utilities. The City of Fontana granted easements in order to accommodate the new underground conduits, cables, vaults, manholes, and other utilities.

Mamco Construction has grown by leaps and bounds since 2009,

with revenue advances to the tune of 75 to 100 percent each year.

Rumzi Alabbasi continues, “We were fortunate in that when other contractors were suffering with debt issues, complicated by much lower revenues, our company was just starting out in the public works sector. We have maintained our competitiveness by reminding ourselves each day to remain lean and acquire people and equipment only as we absolutely need it. As it happens we have purchased eight new pieces of construction equipment in just the past nine months, in order to keep up with our work demand. We turn to RDO Equipment out of Riverside for the majority of our heavy equipment needs. Our current John Deere fleet consists of (2) John Deere 310G and (5) 310SJ backhoes, 644G and 544G wheel loaders, a 318D skid steer and (2) 210LE

skip loaders. Mark Grunewald from RDO Equipment is our sales rep and he has been there along with the RDO customer service team, every step of the way. In the future we will need many more units as we continue to grow and specialize in light utilities and street work.

We want to move into the larger more complex jobs over the next few years. Moving from 6” pipe to 60” storm drain and to accomplish this we will need help from companies like RDO and their John Deere equipment.”

Mamco Construction is located at 16810 Van Buren Blvd., Suite 200 in Riverside, California. For more information, please call 951-776-9300 or visit them online at www.alabbasi.biz/mamco. Cc

When the average person hears about commercial demolition, their mind naturally gravitates towards wrecking balls, blasting, and enormous mounds of demolished concrete and steel. But there is another side to this continuously growing business that seems to take a back seat to this easily imagined activity. It is known as Tenant Improvement (TI) and it requires the demolition of everything from interior walls to carpet, ceiling tile, steel and wood studs, marble, and even sinks and toilets. These demos are done mostly to accommodate the specific needs of the new tenants that are moving into office, retail, commercial or industrial properties. Like their name indicates, Interior Removal Specialists, Inc. specializes in tenant improvement demolition (TI) and their knowledge of

both commercial demolition and the recycling of construction and demolition debris sets them apart from all other companies in the “Green Building” arena.

Founder and President, Carlos Herrera has worked tirelessly to raise the bar for the recycling of C&D debris since his company's inception in 1994. The efforts of Mr. Herrera and his crew of more than 220 employees extend way past what is mandated and into the rarely ventured territory of “what is right”. Richard Ludt is the Director of Environmental & Public Affairs for Interior Removal Specialist, Inc. (IRS) and he explains, “I believe that we are currently the only TI company in the country that owns and operates their own state certified recycling facility. When it comes to recycling construction demolition debris, we go above and

beyond what other TI companies are mandated to do. We started Construction Demolition & Recycling, Inc. with the express purpose of providing diversion by commodity and exceeding the standards set forth by the USGBC LEED requirements. We are different than most demolition contractors in that all we do is Tenant Improvement (TI). We don't knock down buildings, or utilize a lot of heavy machinery.

Everything we demolish has to fit through a standard 3 ft. doorway and exits the building in a 1 cubic yard rolling dumpster. We have 180 hard working individuals out in the field every night doing hand demolition with crowbars and sledgehammers. We load our 2.5 ft. by 3.5 ft. buggies down the freight elevator and onto the loading dock, where it is then tipped and hand stacked into 40-yard dumpsters to maximize space.”

Every C&D facility in the world operates on what is called a “Facility Average”. Due to the amount of truck traffic and debris being poured

into one central pile, it is not possible for a landfill to properly track the diversion rate by load.

Diversion rate is simply the percentage of waste materials diverted from landfills to be recycled, composted, or re-used.

The way they calculate the diversion rate at any C&D facility is simply tons in minus tons of landfill, equals diversion. So if a demolition contractor brings in 100 tons a day and they send 20 tons to the landfill, then they have an 80% recycling rate. In the TI demolition industry, the waste material is less usable, as much of it is light, fluffy, sometimes toxic and traditionally not very cost effective to handle. Because the average C&D facility is dealing with full building demolition, residential demolition, road and bridge waste and parking lot asphalt spoils, and 60 to 75 percent of what is brought into their facility is asphalt, concrete, dirt, metal and dimensional unpainted lumber from framing. So they recycle upwards of 70 percent of their debris, mostly the “low

hanging fruit” and much of the 20 to 25 percent of the soft fluffy stuff that TI contractors deal with goes to the landfill.

Ok, breath. Now we get to the problem with facility averaging in the TI demo industry. When TI debris is brought to the same before mentioned facility, they will traditionally take out the steel, copper, aluminum and any plastic and unpainted dimensional lumber.

These materials make up around 20 to 25 percent of these TI loads, but they give the demolition contractor a certificate that shows a 75 to 80 percent diversion rate. This is what is known as green washing and it does not accurately portray what is actually being effectively recycled.

Material like drywall, manufactured lumber, and carpet simply goes into and stays in our landfills forever.

Interior Removal Specialists, Inc. decided to step up and create their own recycling facility and not only take a stand against green washing, but humbly show the industry how it can and should be done. They

don't handle asphalt or concrete, just that light fluffy stuff that has been so hard to deal with up till now. Richard Ludt further explains, “One of the things we found out was that drywall for instance is just over 26% by weight of almost every job we do. So in a LEED project if we wanted that 75% diversion (2 LEED Points) and the facility we took it to does not recycle drywall, then we are not going to get those LEED points. The issues are materials such as drywall, manufactured lumber, ceiling tile and carpet. We recycle all of this one way or another. The drywall for instance is predominantly gypsum and is covered in paper. We send that off to a company who then grinds it up and sells it to farmers who use it as a soil amendment. Gypsum is a strange commodity in that if you bury it in a landfill, deprive it of oxygen and get it wet, it can produce hydrogen sulfide gas, which is fatal in small quantities. If you take that same gypsum and mix it up with the soil and apply it topically, it is actually

9:19 AM

Page 23

beneficial. We get paid a very small amount for the gypsum, but we have to pay to ship it, then handle it on the job site, separate it in our yard and then load the truck. It works out to around 25 cents a ton cheaper to recycle it rather than dump it in the landfill. It is not necessarily a financial decision, as much as it is the right thing to do.

The manufactured lumber and carpet is sent off to a waste energy facility, where it is burned and the embodied energy turned into electricity. Ceiling tile goes back to Armstrong Ceilings, while marble and granite from counter tops, steel studs, aluminum door frame and copper pipe and wire, which are of course more profitable to handle, are recycled through traditional channels.”

Interior Removal Specialists is leading the way in this niche recycling industry, through the creation of Construction Demolition & Recycling, Inc. Richard Ludt continues, “We have been lobbying the City and County of Los Angeles

and the State of California to change the rules on how they deal with construction demolition debris. We would like them to move away from the facility average mindset and consider diversion by commodity, rather than raw weight.

Unfortunately, we are fighting a long established waste industry that does not want this to happen, because it means more work for them to recover products that are worth far less money. This diversion is going to become mandatory across the board, especially in California. In 1989 California passed AB939, which states that California must recycle a minimum of 50% of our waste by the year 2000. In 2006 the waste board held a press conference to announce, “We did it!”…six years late. But now that we have arrived at 50%, they are already talking about bringing the state wide diversion rate to 75%.

Eventually the cities will begin mandating this, especially since the landfills are closing and they are not building any more of them.

According to the City of Los Angeles, who does our auditing and grants us our official diversion rate, we are doing 76.4 percent diversion of the 20 to 25 percent of the materials that most C&D facilities are actually burying in the landfill. Multiply this by every TI demolition contractor in California and you have not only saved landfill space and created jobs, but you have done the right thing for the environment overall.”

Today, Interior Removal Specialists, Inc. is Construction Demolition & Recycling's biggest customer. They processed over 36,000 tons last year, of that around 98 percent came from their own demolition jobs. They are slowly opening up to the public and with the Puente Hills Landfill about to close, they will most likely see more customers very soon. Interior Removal Specialists' hard work has been recognized in several national magazines, with Construction Demolition Recycling Magazine listing them as #19 on the list of the top 20 demo contractors in the United States. They have also won several international awards for their recycling efforts, including: the Gold 24

and Silver awards from the Solid Waste Association of North America, Gold Metals from the California Resource Recovery Association and multiple WRAP awards from the California Integrated Waste Management Board, including one WRAP Of The Year, Los Angeles County Green Leadership Award and the very first Innovation Award given out by the International Solid Waste Association. They were even featured on the History Channel's popular show, Modern Marvels.

Carlos Herrera started Interior Removal Specialists back in 1994 with only 20 employees and a truck.

Today, IRS is the leader in the TI demo industry and continues to operate on the principal of “Doing What is Right”. Carlos regularly reminds his crew that, “You Can't Go Wrong if You Do What is Right!” To that end, IRS has developed their own donation program that is also very unique in their industry. They work with hundreds of local and international charities, donating more than 20 tons of recovered items every month. Churches, schools, animal shelters, police and fire agencies - no worthy recipient is

ever turned away, and they keep all of those useable materials out of the landfills. To date, they have donated more than 5,000 tons of materials and reintroduced them into the communities from which they came.

Richard Ludt concludes, “Carlos is the inspiration and the moral compass for this company. He always has been and always will be.

We have donated to women's shelters and children's centers, as well as the humane society and many other nonprofits, which can come in and literally outfit an entire office or kitchen for free. Helping the environment and giving back to the community is what keeps all of us doing what we do each day. The rest is really just a business, but a business that all of us at Interior Removal Specialists and Construction Demolition & Recycling are proud to be part of.”

(Above) Pavement Reycling Systems recycling “train” being utilized by the City of Moreno Valley.

The City of Moreno Valley is one of a growing contingent of cities, counties and municipalities that are choosing environmentally responsible and sustainable methods to maintain their local roads, streets and arterials. Through the use of these recycling methods, the City benefits today from the structural and economic value of the resources in its initial construction investment.

For the third straight year, Moreno Valley is utilizing a process known as Cold In-place Recycling (CIR). CIR is a process where the old cracked and fatigued pavement is milled to a depth of two to four inches, crushed, screened and sized to smaller particles that meet a 100% one inch minus gradation. The sized asphalt particles are weighed and blended with an environmentally friendly solvent-less emulsion; this project utilized Western Emulsions PASS R. The blended recycled asphalt is then paved back in one continuous operation. In effect, the old worn out pavement enters the front of the CIR “train” recycling equipment and then the “renewed agency” pavement exits the back in preparation for paving. There are no hot emissions or aromatics with the CIR operation. In

addition, the CIR process eliminates hundreds of loaded trucks that would typically travel over city streets adding to carbon emissions, as well as causing dust and increased traffic congestion. The process also saves hundreds and possibly thousands of barrels of oil when compared to alternative methods of pavement rehabilitation.

This year, the City of Moreno Valley was also looking for a way to use the CIR “train” system to rehabilitate their neighborhood roads. This was complicated by the narrow streets, which made it difficult, if not impossible to maneuver the long and wide machines. Therefore, the City evaluated another environmentally viable alternative method, known as Cold Central Plant Recycling (CCPR), to address the accessibility of recycling equipment. This process recycles the City’s existing pavement resources at an off-site location using a central plant system.

This year the bid was broken down into two separate projects: one for the arterials and collectors utilizing the Cold In-place Recycling method and the other for the neighborhood streets using the CCPR approach. The first

project encompassed approximately 700,000 sq. ft. of CIR, which began in May of 2011. The arterial or collector is a road that typically receives a higher volume of traffic and also links to residential neighborhood streets.

Historically these roads are longer, straighter and can easily accommodate the CIR train. On these surfaces, the City of Moreno Valley chose to use the CIR approach, and elected to use CCPR on the residential roadways. Many of these roads were inherited from Riverside County and designed back in the 1960's, and although some areas had a small layer of base materials, most were only made up of around 3 inches of asphalt over high “R” value compacted native soils. The daily traffic and several trash trucks a week had more than taken a toll on these streets, which over time became fatigued and distressed. Through the use of CCPR, Moreno Valley was able to have the contractor mill and remove the old asphalt pavement down to the top of the existing base. The City’s asphalt assets were hauled to a nearby stockpile site at Pavement Recycling System’s mobile central plant location. Next, the subgrade was re-graded and recompacted. The City’s stockpiled asphalt assets were then recycled in the central plant, where the recycled asphalt was placed into paver hoppers and laid back down at a compacted depth of 3 inches. Approximately two weeks later, a 1 1/2 inch hot rubber asphalt cap was added and the entire section was brought up to 4 1/2 inches and capable of enduring the high volume daily traffic and trash trucks for many years.

CIR is not a new technique. It has been used successfully for over twenty years in other parts of the country because of its proven benefits in improving

roadway structural sections in a cost effective and environmentally friendly manner. It is now being used more prevalently in California due to the rising cost of oil, the imperative need to reduce greenhouse gases and the related reduced impact on the community. CIR use is just one of many options the City of Moreno Valley is exploring in order to do its part in saving the environment, providing smooth riding roads and saving tax payer dollars for its citizens. James Emerson of Pavement Recycling Systems comments, “The City of Moreno Valley was able to utilize the CIR method on one project and the CCPR approach on the other at a substantial savings when compared to the grind and overlay method. Moreno Valley is a growing city that began as more of a commuter or bedroom type community. Their population over the past 20 years has increased dramatically and their roads have encountered more intense stress than they originally anticipated. Due to the budget constraints that all cities are currently experiencing, it was beneficial to them to recycle what they already own in asphalt assets and then add an additional hot rubber cap to the structural section.

With the cost of oil continuing to escalate, cities like Moreno Valley are able to realize an overall cost savings of 40 to 50 percent over other methods.”

The City of Santa Ana, another agency in their third year of recycling their pavements, and with over 260 miles of roadway recycled, have reported as much as a 72% savings, when compared to other rehabilitation methods.

The savings is important, but it is not the only reason many agencies are turning to these methods. The convenience is also a major contributing factor. In most cases a resident can leave for work in the morning on a

paved surface and return home that evening on a newly paved recycled roadway. The distinguishing benefit of the CIR train approach is that it recycles the asphalt section in one pass, leaving the roadway virtually intact at all times.

Both methods of asphalt recycling are extremely sustainable, but it is important to note that maintaining and preserving these pavements is just as crucial as it is with other methods. Both CIR and CCPR are engineered processes based on the use of the existing pavement resources in the design of a new pavement structural section. Cores and samples are taken and sent to an approved lab, where a mix design and job mix formula is conducted and provided to the agency’s engineer. The recycle plants take the existing asphalt and crush it to the specific required gradation. It is then blended thoroughly with solvent-less engineered emulsion and then paved back with traditional paving equipment. One roadway may require a 2 percent engineered emulsion, while another may use over 3 percent depending on the results of the mix design. Technology and equipment have officially evolved to the point where more agencies are using the CIR and CCPR processes at the urban level with great success and at a substantial cost savings.

The Federal Highway Administration has been utilizing this technology for over 30 years now in the state of California. Caltrans has successful applications that now date over 20 years. Local cities have come on board more over the past few years, with Moreno Valley being one of the front runners in the new generation of recycling cities.

Henry Ngo is the Senior Engineer for the City of Moreno Valley and he comments, “We looked at the pros and the cons of these unique roadway rehab and resurfacing

techniques. Along with the obvious cost benefits, we also liked the limited impact that these solutions offered to our local citizens. It definitely limits the time that we need to interrupt commuter traffic; however, the CIR process did not address our need to repave our small local streets that are only 24 feet wide.

The Cold Central Plant resolved this dilemma, while also insuring that we replace the exact thickness needed.

Pavement Recycling Systems visited us around four years ago and began to educate us on the benefits of Cold Inplace Recycling and now we are also utilizing cold central plant recycling to great success. The benefits have been many and we hope to continue to use these efficient rehabilitation methods in the future.”

Pavement Recycling Systems, Inc. is the leader in asphalt recycling in the Western United States and specifically California. They strive to educate agencies on a full range of environmentally sound solutions for all stages of the pavement lifecycle. James Emerson of Pavement Recycling Systems concludes, “We are committed to the belief that recycling is the best longterm solution to the pavement portion of our nation's infrastructure challenges. We endeavor to help agencies use their existing infrastructure investments, by effectively reducing cost, energy use and the carbon footprint.” For more information on Pavement Recycling Systems, Inc. and recycled pavement solutions, please call 800-966-7774 or 951-682-1094.

(Top Right L to R) Joe Moyer, Operator, Bill Rash, Vice President Construction, Charles Howard, General Manager, Jeff Nelson, President - NPG Corporation and Alan Hahn, Nixon-Egli Equipment Co. and Mark Chandler, General Services, NPG Corp. (Above & Right) NPG Corporation’s new Wirtgen W 150 milling on a residential street in Riverside, CA.

NPG Corporation is a family owned business that was started in 1961. The company employs 50-70 field employees and has an office staff of 12 to ensure prompt and reliable service. Asphalt Construction NPG is owned and operated by NPG Companies, an investment group, and operates as a A, B, C-12 licensed company. NPG Companies also owns GoldStar Asphalt Products, leading and supplying the industry with paving products and rental equipment needs. According to Jeff Nelson, President, “We are adding to our rental fleet with this new Wirtgen machine and we are currently negotiating for an additional Wirtgen milling machine and pulverizing unit.”

NPG recently took delivery of a brand new Wirtgen W 150 cold milling machine from Nixon-Egli Equipment Co. Mark Chandler, General Services, NPG Corp., comments: “We were in the market for a milling machine to compliment our fleet. The Wirtgen W 150 is a very versatile large milling machine in terms of capability, but nonetheless maintains physical compactness for easy maneuverability. The main reason we bought it was that it could be used on a variety of different applications. One of the features that really sold us on the Wirtgen W 150 was the LEVEL PRO leveling system. This system enables us to regulate precise milling depths and slopes from the platform. Another feature we really appreciate is the Parallel-to-Surface technology. This automatically keeps the cutter housing level as the unit moves into a cut. These two features have made the Wirtgen W 150 extremely user-friendly.”

Mark adds, “Nixon-Egli Equipment has been great to work with. We’ve bought other machines from them in the past so we know we can depend on them. They were very helpful throughout the entire sale. We’ve known our salesman Allen Hahn for many years and he has been there every step of the way. Mike Burns from Nixon-Egli’s service department has provided great product support. His knowledge about the machine and his patience and ability to teach us on the jobsite has been immeasurable. We’re really pleased with the results we’ve had with the Wirtgen product and with our support from Nixon-Egli Equipment Co.”
