Abstract：The skid resistance decay law of steel slag asphalt pavement was studied by accelerated loading equipment,and the skid durability,abrasion resistance and its texture evolution law of steel slag pavement were analyzed by high-precision three-dimensional scanning technology and multiple fractals.The results show that the slip resistance of steel slag asphalt pavement decreases rapidly in the pre-loading period(400 000 times),the decreasing trend slows down after 400 000 times,and the slip resistance of steel slag asphalt pavement decreases by 22.57%after 1.2 million times of loading.With the increase of loading times,the more inhomogeneous the pavement texture is,its complexity decreases,and the skid resistance is weakened,BPN、MTD and Δα,Δf(α)were fitted better,and their correlation coefficients,R2,were 0.94 and 0.95,respectively,and the decay fitted to BPN、MTD,Δα,and Δf(α),and their correlation coefficients,R2,were 0.96,0.97,0.92,and 0.93,respectively.
