The Design Method of Aggregate Gradation of SMA-16 Modified Asphalt Mixture Based on Road Performance

Abstract

established through a large number of road performance test, the road performance of SMA-16 modified asphalt mixture is predicted in the design calculation process. The gradation test prediction models are established to identify the skeleton structure type of asphalt mixture. The asphalt mixture design method of SMA-16 modified asphalt mixture based on road performance is proposed on the basis, which makes the SMA-16 modified asphalt mixture achieve the optimal in the design process and reduce the unnecessary test amount.
