| Abstract: | Based on the analysis of the grain gradation characteristics of waste and old asphalt mixture obtained from cutting the old asphalt pavement, this article discusses the feasibility of using the waste and old asphalt mixture stabilized by the lime, flyash and suitable sand as the pavement basement mixture, proposes a mix proportion design method of controlling the lime - flyash dosage according to the aggregate shake porosity to meet the requirements of the basement intensity and crack resistance, and through the indoor experiment data and the real deflection measured in the site construction testifies that this technology is scientific and practicable. |
| Keywords: | pavement basement lime - flyash waste and old asphalt mixture shake porosity mix proportion design |
