ACPA recently hosted an Overlay Summit in Rosemont, IL. Guests from ACPA Chapters, the CP Tech Center, and other experts gathered to discuss overlays that bonded to asphalt and how they are performing after certain margins of time. The summit was a result of a continued discussion about the need to promote overlays throughout the industry. Additionally, the group celebrated the 5-year anniversary of PavementDesigner.org.

Ferrebee attends Sustainable Pavement Technical Working Group Meeting
FHWA’s Sustainable Pavement Technical Working Group (SPTWG) met in San Diego last week. Eric Ferrebee, ACPA’s Senior Director of Technical Services, is a member and represented our industry at the meeting. The SPTWG is leading the efforts to implement EPDs, and the meeting focused on this as well as continued discussions on sustainable efforts. Ferrebee and our industry partners from NRMCA, MIT Concrete Sustainability Hub, and the CP Tech Center advocated for the importance of including the entire lifecycle into consideration in pavements, albedo, and carbonation.
ACPA Represented at ACI Concrete Convention
Senior Vice President of Engineering, Tim Martin, and Eric Ferrebee are in Dallas this week at the ACI Concrete Convention participating in committee meetings on concrete pavements and materials. Martin and Ferrebee focused on giving industry and ACPA updates during these meetings and making sure priorities align across stakeholders. Ferrebee also sat on a panel with industry partners Tom Van Dam of NCE, Kurt Smith of Applied Pavement Technology and Andy Naranjo of TxDOT on concrete roundabouts and successful construction case studies.
Concrete Temperature Measured in Arizona
ACPA’s Pavement Innovation Director Larry Scofield recently visited pavements in Phoenix that are a part of a cool pavements program, which applied a product aimed to keep asphalt pavements cool. The asphalt pavements treated with the technology were 9-12 degrees warmer than a 48-year-old concrete sidewalk adjacent to the road.
Maricopa County, the country which houses Phoenix and the surrounding suburbs, saw 172 days over 95 degrees in 2020, and concrete’s natural ability to keep and hold cooler temperatures is key to mitigating this heat. After just two years of the program, it remains clear that concrete pavements retain their sustainable attributes and maintain a cooler temperature. Scofield’s full field review of this issue can be read here.
