Laboratory tests to evaluate Superpave consensus and source aggregate properties were conducted to ensure that the local aggregates complied with the standard requirements for use in both mix design systems.

Results from the volumetric analysis indicate that the optimum binder content of Marshall-designed mix is more than the Superpave mix for one quarry and almost the same as the Superpave-designed mix for the other quarry.

Results show that the Superpave-designed mixtures performed better in rutting and are less susceptible to moisture damage than the Marshall-designed mixtures. Tests were also conducted with the Superpave Simple Performance Tester (SPT) in an effort to predict moisture damage using the SPT dynamic modulus test. Correlation studies between SPT dynamic modulus and the AASHTO T283 moisture susceptibility test results showed a strong relationship. The SPT dynamic modulus test results were also found to correlate well with the dynamic creep, wheel tracking and resilient modulus tests. In general, correlation between the results from the SPT dynamic modulus and these tests to evaluate rutting shows moderate to strong relationships.
