【 摘 要 】

The road performance prediction models are established through a large number of road performance test, the road performance of GAC-20 modified asphalt mixture is predicted in the design calculation process. The gradation test prediction models are established to identify the skeleton structure type of GAC-20 modified asphalt mixture. The GAC-20 modified asphalt mixture design method based on road performance is proposed on the basis, which makes the GAC-20 modified asphalt mixture achieve the optimal in the design process and reduce the unnecessary test amount.
