Abstract

Gradation designs of AC-16 dense-graded asphalt mixture are conducted separately using the Marshall Compaction method of China and Superpave Gyratory Compaction method of America. The indexes determined by these two design methods are compared and analyzed. The results show that the optimum asphalt content determined by Superpave Gyratory Compaction method is a little more than that determined by Marshall Compaction method, and Superpave Gyratory Compaction method is better than Marshall Compaction method in pavement performance such as dynamic stability, freeze-thaw split tensile strength ratio, residual stability and so on.
