Abstract:Employing the rolling thin film oven test and ultraviolet radiation aging test, the penetration index, soft point, ductility and viscosity of AH-90 Asphalt and other additives modified asphalt were investigated. The results showed that the ultraviolet radiation aging would greatly effect the performance of asphalt, but the performance can be improved to a certain extent by adding some additires. Then, it was also proved that the additives can improve the anti-aging performance of asphalt by the rolling thin film oven test.
