A New Method of Gradation Design about Rutting Resistance of Asphalt Pavement

Abstract:

The article derived the formula of continuous particle size of asphalt aggregate packing density based on the Stovall model; according to the relationship between porosity and rutting, rutting prediction model was established; by experiment to determine the parameters in the formula to be determined , and the applicability of the formula was verified, the results showed that: the formula can calculate air voids and dynamic stability of asphalt mixture by aggregate size distribution and the aggregate ratio .
