Experimental Research on Causes for Asphalt Pavement Rut

In accordance with lab trial of wheel rut under different influencing factor,the paper analyzes by contrast the rut-resistances of adopted average concrete mixture and modified asphalt mixture,respectively getting the varying curves of the dymamic stability of asphalt mixture with the different traffic load,temp,water,asphalt and composed mixture.Researching results indicate that the average asphalt mixture is preceded by SBS modified asphalt in rut-resistance,simultaneously determixes the varying law of asphalt mixture under action of different load,temp,water,asphalt and mixture.
