Abstract:
Permeable friction course (PFC) mixes have proved to be excellent mixes that show several desirable characteristics that are sometimes short-lived, so that several districts have restricted their use because of premature raveling problems. Other problems noted involve surface fusion where the PFC loses its drainage capabilities.
Researchers sought to address those issues by:
1. Focusing on developing new lab test protocols at the design stage to potentially eliminate mixes with stripping susceptibility.
2. Monitoring performance on sections constructed with new specifications, with changes aimed at minimizing performance problems.
3. Constructing an automated splash spray monitoring system to measure how existing PFC pavements are performing, thereby helping to optimize future designs.
