Equivalent Conversion Method of Asphalt Pavement Axle-load Skid-resistance Performance
First, the axle-load skid-resistance conversion formula of asphalt pavement was established in accordance with the equivalent principle of skid-resistance performance attenuation which is similar to the way of axle-load equivalent conversion for asphalt pavements structure design. The way to determine the axle number coefficient and wheel number coefficient was also proposed. Second, the prediction method of skid-resistance life of asphalt pavement was put forward on the basis of the axle-load skid-resistance equivalent conversion formula. Afterwards, the skid-resistance performance attenuation tests for asphalt mixture SMA16 were carried out on a selected expressway under various wheel pressures. Finally, by using the deduction of fatigue equation of asphalt mixture for reference, the skid-resistance fatigue equation for SMA16 based on BPN value was derived to predict the skid-resistance life of the expressway pavement. The results indicate that it is feasible to study skid-resistance performance of asphalt pavements with the skid-resistance performance of equivalent conversion method.
