| Abstract: | This paper analyzes ultra-thin wearing course material. The results and analyses show that gradation and asphalt aggregate ratio of the material meet the standard of AC-13 Technology, and ultra-thin wearing course material can be regenerated. High temperature stability, moisture stability, low temperature property meet the requirements of HMA in specifications. Pavement compactness, smoothness, water permeability coefficient index can meet the requirements of specification after regeneration. |
