Some studies had suggested pavement’s skid resistance performance was affected by lots of factors, not only by pavement materials structural [1]; The optimal content of asphalt had been determined when the skid resistance performance was in the best form by research on influence of aggregate gradation on the performance of porous asphalt pavement [2]; Skid resistance performance could be improved by adding sisal fiber in asphalt mixture [3].
The coating is consist of 1) adhesive materials, the epoxy products and flexible asphalt mixtures; 2) aggregates of wear-resisting, that is emery and bauxiterefractory.
