• Grizzly Cub telescoping single-bar frame and extension sleeve for 6 feet to 15 feet, 6 inches with no bearings. It incorporated all the patents. • Sliding or clamp on third middle arm holds 1-foot to 8-foot rolls centered or off-centered, increasing versatility. • Multi-bar telescoping PVC-tensioning system keeps fabric taught. • Multi-bar PVC Grid Roller System keeping it taught and not impeded before brushing. • Telescoping chevron angled brushes that sweep fabric from the center to the outside, eliminating most wrinkles. Brushes can be straightened for installing grids. • Rotating spindle-braking roll holders with special machined discs and caliper brakes that control the roll's turning speed. They can be adjusted independently, making it possible to pull fabric on curves. In addition, Barazone has a patentpending on 335°F, high-melt brushes made of modified plastics, can be cleaned at the end of the job, will last longer, and which feature 50 percent more bristles to reduce fabric wrinkles. And to reduce costs and speed installation, Barazone developed an oil-truck mounting system that eliminates the tractor and operator and enables the geosynthetic to be installed as the oil is sprayed down in one operation. In 1988 Barazone developed the Grizzly Cub 300T with a sleeve that allowed both telescoping arms to telescope inside each other and extends the Cub’s mechanical arms to 15 feet, 6 inches with no bearings. The Cub installs material the same as the Grizzly 600T and included all the patents with fewer standard features which are options, designed as a less-costly alternative that installs fabric no wider than 15.5. Barazone says 2018 was on pace to exceed a record 2017, but the CARR Fire wildfire in California destroyed GAC’s 39-year-old manufacturing facility. So GAC is in the midst of rebuilding its manufacturing operation and this spring the Grizzly 600T will be back in production.
Girish Dubey, STAR Inc. Girish Dubey has been a strong proponent of the sealcoating industry since he assumed the presidency of STAR Inc. in 1988. A regular speaker on some of the more complex aspects of sealcoating at National Pavement Expo and National Pavement Expo West, he is a contributor to Pavement Maintenance & Reconstruction, a founding member of the research-oriented Pavement Coatings Technology Center, an advocate for refined coal tar sealer, and an encouraging voice on the technical and sometimes difficult aspects of pavement sealer. But perhaps most important has been his drive toward openness in the industry, toward sharing information among manufacturers and among contractors – all with an eye toward raising the performance of pavement sealer and along with it the professionalism of the industry. Dubey’s efforts stem directly from his background – he has a Masters in Polymer Chemistry from Wright State University – and his belief that industries advance by sharing research from all sources – even private companies. A Career in Pursuit of R & D In 1976 following research positions at PAP and Tremco, Dubey joined Maintenance Inc., a division of Premier Industries, where he worked in research and plant operations. In 1979 he joined Cambridge Coatings, a paint company, working with paint chemistry and formulations of coatings – and most importantly he got involved in the Federation of Societies for Coatings Technology, (FSCT) which fed his desire for research and sharing of information. “I was very active (FSCT chair in 1983) and learned a lot about paints
and coatings, and I enjoyed it,” he says. “The beautiful part of that is that all the information including technical knowledge is freely shared. It was very different from sealcoating, which was a guarded technology.” From 1983-1987 Dubey was technical manager and general manager of Hempel Marine Coatings in Saudi Arabia, and in 1987 the STAR Group (formerly Cosmicoat franchises) approached Dubey to take on the responsibility for quality control and quality assurance for their sealer. In 1988 Dubey became president and stepped right into the lab to help streamline sealer formulations. Today he still spends almost half his time in the STAR lab, hands-on in research and development with other STAR chemists, and under his guidance STAR now produces a comprehensive range of pavement maintenance products including various types of sealcoatings, performance- boosting additives, concrete coatings, primers, color coatings, and several crack fillers. A Shift to Licensing A major change Dubey brought to STAR was the shift from franchise operations to technology licensing. STAR provides its licensees with a complete set of formulations for sealcoat manufacturing, then provides support through testing and marketing. The company will also provide building plans, guidance on equipment selection and set-up and will even construct the plant for the licensee. STAR develops the sealer formulations, researches and tests the materials to be used in sealer manufacturing (such as clay, fillers, refined tar, asphalt, specialty binders and chemicals, etc.) then approve several suppliers for each raw material and negotiates pricing. “In the manufacture of sealer licensees have to use the materials specified by us, but they can buy from any of the suppliers we approve. They don’t have to buy through us,” Dubey says. Once a licensee begins manufacturing sealer, STAR checks samples on a regular basis: The first 10 batches of sealer are sent to the lab and then STAR also checks every 10 batches after that. “For those services we charge a royalty fee based on number of gallons produced,”
