Best Practices for RAP Use Based on Field Performance Status: CompleteReport Date: 04/20/2009 Summary: Researchers examined whether asphalt pavements containing recycled asphalt pavement in the wear course are prone to early failures. They conducted a survey of county engineers and tested samples from selected projects for dynamic modulus and other properties. Results showed that field performance of pavements depended more on the low-temperature performance grade of binders and the stiffness of underlying layers than on the percentage of RAP in the wear course mixture.
