Abstract:

In order to improve the rutting resistance of asphalt mixtures in the middle course to reduce the rutting of asphalt pavement, the influence of different types of gradation with their own optimal asphalt-aggregate ratios is analyzed. Some investigations are made out on the mixture in the middle course through the modified wheel tracking test in air bath and the Hamburg wheel tracking test(HWTT)in water bath, and the results of which are compared with the corresponding research in Germany.Results show that the Sup20 and the modified AC-20I have better performance than that of AC-20I under the same test conditions.In addition, the high-quality bitumen and hard aggregate can improve the rutting performance of the mixture in water-submerged conditions.The selection of modified asphalt, hard aggregate and a reasonable gradation are essential to the improvement of the rutting resistance of the mixtures used in the middle course.
