Analysis of Rutting Test Method of Asphalt Mixture and Index Limitation

High temperature stability of asphalt mixture is controlled through the dynamic stability parameters of rutting test in the design of current pavement materials.Through the summary of the whole rutting test procedure,the influence of the size,shape and voidage control as well as test temperature of test parts,test load and other factors on the test result are analyzed.Meanwhile,the calculation methods of technical index of rutting test are analyzed.Through the contrast with other rutting test methods at home and abroad,the present standard rutting test methods and limitation of index are analyzed comprehensively.
