Theory Analyses of Effect of Topography on Skid Resistance of Asphalt Pavements

Skid resistance was one of the most important properties of asphalt pavements Based on the analyses of characteristics of asphalt pavement and mechanism of tire -road friction , the effects of topography on skid resistance of asphalt pavements was discussed using theories of tires , viscoelasticity and rubber friction The following results were acquired Skid resistance of asphalt pavements was affected by the height and density of aggregates forming macro -texture and the height , density , sharpness of asperities forming micro -texture Asphalt pavements had better skid resistance as the height and density of aggregates were bigger The bigger the height and density of asperities , the better skid resistance of asphalt pavements Asphalt pavements with sharp asperities had better skid resistance than those with blunt asperities
