Abstract
Based on results of wheel rutting test, the factors, including the percent of coarse aggregate, the gradation of coarse aggregate, bituminous, the density of mixture, the ratio of filler to bituminous are studied for the effect on the high temperature properties of SMA, the anti-rut characteristics of SMA which are designed with GTM method are also discussed, finally the asphalt mixtures of AC and AK are contrasted to SMA. The results indicate that the ratio of filler to bituminous and the performance of bituminous have much more effect on the anti-rut characteristics of SMA than its gradation;SMA that is designed with GTM method is better than with MARSHALL on the high temperature property;SMA with the dense skeleton structure has the highest temperature stability;AK-16A which is designed with GTM method is better than SMA.
