The study on the Anti-sliding attenuation law of the up-layer bituminous pavement is of great practical significance. Through analyzing the effect factors which affect the anti-sliding performance of the up-layer bituminous pavement, combining with the investigation data of on-the-spot traffic volume and the testing data of on-the-spot transverse force coefficient, aiming at "Super-12.5" up-layer bituminous pavement this paper established an attenuation model of the anti-sliding performance. Using which, we can forecast the change of anti-slidi...
