| Abstract: | Water erosion is one reason of asphalt pavement deformation in the early term. On the North Section of Jing-Zhu Expressway, there are large precipitation, dense fog, poor visibility, heavy traffic and serious surcharge in area along the expressway. So how to assure water stability of pavement is one of ticklers in SMA mixture design. In this research, SMA mixture gradation design and water stability are studied scientifically, emphatically influencing factors such as raw material capability, admixture, coarse aggregate content and mineral aggregate gradation are researched deliberately. |

| Keywords: | SMA gradation design water stability coarse aggregate content mineral aggregate gradation admixture |
