Abstract
In this paper, firstly, based on asphalt pavement central layer, the comparison with the foreign related gradation of asphalt mixtures, one typical kinds of gradations are decided; Secondly, the asphalt aggregate ratio is predicted based on professor Lin’s Theory , and five asphalt aggregate ratio are selected. Finally, the road performance of asphalt mixture is experimented, and the road performance of five asphalt aggregate ratio is analyzed. As a result, we can predict the range of the optimum asphalt aggregate ratio based on the road performance.
