摘要：

To evaluate the modification effect of phosphorus slag powder (PSP) on the rheological performance of asphalt, five types of PSP with different particle sizes and different content were prepared and added into the AH-70 base asphalt. The dynamic shear rheometer (DSR) test was used to evaluate the influence of PSP content and particle size on the rheological properties of asphalt. Rolling thin film oven test (RTFOT) and pressure aging vessel (PAV) were used to simulate the asphalt aging after modification of PSP. The influence of aging condition...
