| Abstract: | This paper takes the amount of mining ash as a variable factor and puts it into asphalt mixing ratio design together with asphalt amount. The double-variable factor mixing ration design is carried out with quadratic regression cross test, which makes asphalt mixing material have better mechanical properties and low cost index. |
