Laboratory evaluation of the effect of temperature on skid resistance of different asphalt mixtures

摘要

In this research study, the effect of pavement surface temperature on skid resistance of differentasphalt mixtures has been investigated. Four types of asphalt mixtures including Hot Mix Asphalt,Stone Mastic Asphalt, Steel Slag, and Porous asphalt were heated to different temperatures and theirrespective skid resistance values were measured, using a British Pendulum Tester. In order to evaluatethe effect of heating method on skid resistance variations of asphalt mixtures, two heating sourcesincluding water bath and oven were used. Results indicate that skid resistance of studied asphaltmixtures decreases as surface temperature increases. Also, type of heating method has no significanteffect on the skid resistance variations. In addition, based on experimental results, equations areproposed to describe the relation between skid resistance of different asphalt mixtures and surfacetemperature.
