supply of liquid asphalt binder in two 30,000-gallon insulated vertical storage tanks. A drag conveyor carries processed mix to one of three 300-ton storage silos that comprise the New Generation Storage System. The relocatable plant is supplied by six cold feed bins and three RAP bins. An 80,000 CFM Mod Reverse Pulse Baghouse with a Variable Frequency Drive exhaust fan system for energy efficiency, and an 11 ft. 6 in. by 26 ft. 9-1/2 in. pilot control center completes the main component investment. The reason Pierson chose a relocatable plant versus a stationary plant is because the set-up time is faster. “We wanted to get this plant up and running as soon as we could because

production facility located in Bridgeport, NJ, Pierson upgraded that plant over the years and investigated ways to expand production at other locations. “We bought two new Astec/ Dillman plants in 2016, one for our Cinnaminson, NJ location, and one for our Hillsborough, NJ site,” says Slavic Mokienko, general manager for Pierson Materials. The Cinnaminson Plant The Cinnaminson 500 TPH Unified Drum facility, which includes both Astec and Dillman components, was brought online in June of 2016 at a site once occupied by an old 1-1/2-ton batch plant. It took several months to make
adjustments in order to reach full production capabilities. “Asphalt plant sites are hard to acquire due to strict local and state regulations,” Mokienko notes. “We bought the site in order to acquire the permit.” The other new plant, located in Hillsborough, will be in full operation by this fall. The Dillman 9 ft. 6 in. by 54 ft. counterflow drum, featuring 3/8in. constructed V-type veiling flights, is fired by a Phoenix 100 MBTU burner that can run on natural gas, #2 fuel oil

we knew it would be more efficient to run and allow us to produce and store a variety of mix designs needed to serve our projects, as well as those of other contractors we sell to,” Mokienko states. “With the 500 TPH production capability, we can easily reduce our

output to 200 TPH and still operate efficiently,” Mokienko says. “We have 50 dump trucks in our fleet and will rent the services of 150 truck drivers a day to supply projects, so having a plant that can quickly increase production has been a significant improvement to our production capabilities. “We also support two to four of our own paving crews during peak season, and that’s always a primary need you have to be able to fill to keep projects on schedule with quality mix that meets specifications.”
