P-1 Fiber Reinforced Asphalt Concrete
Summary- Adding fiber reinforcement to asphalt concrete creates a 3-dimensional matrix designed to resist reflective cracking and prevent rutting. This study will evaluate and compare fiber reinforced asphalt concrete to conventional/ polymer modified asphalt concrete on both a performance and cost basis to determine if continued use as part of the County’s resurfacing program is warranted.
Status- Construction on this project was completed on May 25th,2021. This project is currently in the evaluation phase. The last evaluation (24 month) was conducted in Spring 2023. The next evaluation (36 month) will occur in Spring 2024. Moving forward evaluations will take place annually. Annual evaluations will occur for 5-7 years post construction

P-2 100% RAP Pavement Seals
Summary- This pilot will evaluate the performance of both 100% RAP chip and slurry seals compared to conventional control sections, to identify methods to reduce the use of virgin aggerate.
Status- In Construction as part of the FY 21-22 annual resurfacing projects. Construction expected to be complete by early summer 2023.
