摘要：

Based on the concept of low carbon environmental protection, the used asphalt mixture was recycled and measured to determine the asphalt content of 3.8%, and to determine the regeneration mixture gradation of AC-20, the optimum asphalt content of regeneration mixture was 4.9% determined by Marshall test, and then, fly ash was added to asphalt mixture from central plant hot recycling, the performance was studied with different mixing amount of fly ash, results showed that: the performance of regeneration mixture is improved by mixing fly ash, and with the increase of the mixing amount of fly ash, the improving effects of high temperature anti rutting resistance and low temperature stability and water stability and fatigue resistance of regeneration mixture are more obvious.
