• Abstract:
  The most severe performance problems found with existing PFC’s is raveling as shown below in the photos taken from actual pavement projects in Houston and Pharr. This damage is caused when moisture is trapped within the PFC matrix breaking the bond between the asphalt and the aggregate. To improve the quality of current PFC’s it is important to introduce a moisture susceptibility test to be run during the mix design phase. No such test currently exists for PFC’s in the current specifications. The following pages present a moisture conditioning test for PFC’s, in the severe case samples fail during moisture conditioning. Other conditioned samples do very poorly in performance test such as the Cantabro Test. According to the scheduled Product P1 is to be delivered at the end of Task 4, that will be at the end of September 2013. This following version should be viewed as tentative. It may be revised before the end of Task 4.
