Use of PFC to improve teh performance of CRCP

Results of a recently completed project in the San Antonio district show that an overlay with Permeable Friction Course (PFC) can dramatically improve the performance of a Continuously Reinforced Concrete Pavement (CRCP). This project is the first of it’s kind in Texas. However, this practice has gained widespread acceptance in Arizona. As a result of their previous successes, the Arizona Department of Transportation (ADOT) recently launched a campaign to use PFC to overlay most, if not all, existing CRCP in the greater Phoenix area.
