Description:The main objective of this study was to evaluate the ability of a new asphalt composite pavement design to economically reduce rutting, on asphalt pavements. In addition, the longevity of the pavement was to be assessed by determining the durability and permeability of the seal, its resistance to moisture damage in the lower layers of the pavement, and the overall pavement performance. The performance data does not support the use of the rut-resistant composite pavement design. Although there were only a few failures due to stripping, the extent of the failures were significant enough to warrant discontinuing the rut-resistant composite pavement design. The failure mechanism in the RRCP was not due to rutting or cracking, but appears to be directly associated with stripping caused by hydrostatic pressure immediately below the PMSC layer. The conditions which are present when stripping occurs are heavy traffic, high temperatures, and the presence of moisture.
