Pavement-preservation conference prompts pilot interest; vendor pitches EFA seal for lowcountry roads
Summary
Beaufort County staff and contractors described newer pavement-preservation techniques at a regional conference; vendor GAF proposed an epoxy-fortified acrylic (EFA) seal as a pilot option and offered contractor training and performance data.
Brian, county transportation staff, reported on takeaways from the Southeast Pavement Preservation Conference and on South Carolina DOT programs that could expand preservation options for the county.
At the meeting, vendors and DOT representatives discussed broader use of preventive treatments. Brian said South Carolina DOT now allows up to 10% of district funding to be used for preservation and is expanding preventive maintenance to include "fair" roads, not only those rated good by pavement-quality indices; he also described the Transportation Pooled Fund PM 3 project and said DOT had allocated part of its research funds to scrub-seal trials.
Corey Maryland, business development manager for GAF Roads, presented the company’s EFA (epoxy-fortified acrylic) seal and proposed a pilot on county roads. Corey said the material is a two-component, water-based system manufactured with aggregate added at the plant; he told the committee the product has been used in other U.S. markets and that field installations and accelerated lab testing show extended surface life. “Higher performance material gets you better results,” Corey said, pitching the technology as a product substitution for microseal, slurry seal and chip seal.
Corey said estimated installed cost ranges from about $5 to $6 per square yard, depending on contractor and site conditions, and that contractors must complete a two-day manufacturer certification to be part of GAF’s certified network. Committee members asked for references and local contractor availability; Corey said a certified contractor in Columbia was currently supplying work in the region and that GAF would supply training for local bidders.
Staff also reported operational trials planned locally, including a mastic pothole patching kettle to address damage at the Daufuskie Island fire-station turn, and described the county’s ongoing rejuvenator contract, which staff expected to complete later in the week.
Ending: Committee members asked staff to consider GAF’s product for a pilot on candidate microseal/microsurface routes and to obtain references and pricing details for local consideration.
