Abstract
In order to improve the high-temperature stability of No.19 asphalt mixture,the authors analyzed the influence of the aggregate grading,the types of asphalt,the dosage of asphalt,the crevice rate,the methods of compaction,and experiment temperature on the high-temperature stability of asphalt mixture.The experiments indicate that both the aggregate grading and the performance of asphalt have the influence on the high-temperature stability of asphalt mixture.When the best asphalt-aggregate ratio is 0%～0.3% and the crevice ratio is 4%,the high-temperature stability of asphalt mixture is best.
