The high-strength powder colored asphalt was studied by sieve analysis, density and cone penetration test in order to study technical performance. Secondly, the mixing process of colored asphalt mixture was put forward through the Marshall Compaction test. The best whetstone of the colored asphalt mixture was determined by Marshall Test design method. Finally, the variation of pavement performance for colored asphalt was analyzed by the rutting test, immersion Marshall Test split and freeze-thaw test and low-temperature bending test. The results showed: the high temperature performance of colored asphalt mixture was outstanding, but the low temperature performance was lower. Therefore the high-strength powder colored asphalt mixture is suitable to be used in high temperature areas.
