This paper describes a model for estimating mixture rut resistance using the concept of mixture resistivity,to verify the usefulness of the proposed model field rutting data from MN/Road,WesTrack and the NCAT Test Track were modeled,using resistivity,Ndesignand relative field density as predictor variables.

At different temperatures and contact stress,the comparison of rut resistance between two types of mixtures is analyzed.

The influences of content of flat, long and thin particles on rutting resistance of hot mixed asp.

Based on the Marshall,rutting & low temperature banded testing results of SMS-16,AC-16I,AK-16I,with single diameter coarse aggregate grading,their anti-rutting and anti-cracking ability has analyzed in the paper.

Fractal description method of asphalt mixture rut resistance;

According to the results of DSR test,Marshall test,rutting-test and asphalt pavement analysis(APA) of SBS physical and chemical modified bitumen mixtures,the comparison of rut resistance between two types of modified mixtures is analyzed.

The optimal design method of rut resistance property of asphalt mixture was introduced.

By modifying the character of asphalt and designing the proportion of asphalt mixture with anti-rut agent in laboratory,the result suggests that asphalt mixture with anti-rut agent has excellent quality and simple technics,which can direct the produce of asphalt mixture and pavement construction.

Lots of lab test were done to investigate the rut resistance of AC-20 asphalt mixture intermingled with anti-rut agent Che Zhe Wang,the changes of rut resistance under conditions of different tar-rubble ratios and testing temperatures.

Based on analyzing the mechanism of Duroflex applied to Asphalt Mixture,this paper makes the test of the Performance of AC-16 intermingled with different quantity of anti-rutting agent Duroflex,and studies the optimum content of Duroflex,in order to improve the performance of the asphalt pavement.
