Study on Rut Deformation Law of Asphalt Pavement and Its Correlation with Mechanical Properties
In order to find a simple and accurate mechanical index to evaluate the high temperature performance of asphalt mixture,on the basis of studying the rut deformation law of asphalt mixture,the linear correlation between compressive strength,Marshall stability,splitting strength,flexural strength and rut depth was studied.The results show that the rutting depth of the mixture increases rapidly first and then tends to be stable with the increase of load times,and increases significantly with the increase of temperature.The compressive strength index(compressive strength,Marshall stability)has a good correlation with rutting depth,while the tensile strength index(splitting strength,flexural tensile strength)has a poor correlation with dynamic stability.The correlation between shear strength and rutting depth is as high as 0.98,which can accurately and effectively evaluate the high temperature rutting resistance of the mixture.
