Study on Skid Resistance Durability of Epoxy Asphalt Ultrathin Wearing Course Based on Indoor Accelerated Wear
Based on the wet wheel wear test,the effects of wear time and pollutant distribution on the anti-sliding performance of epoxy ultra-thin anti-sliding wear layer were studied.BPN,TD and loss rate of wear mass of extended accelerated loading wear test specimens were used to evaluate the road performance of ultra-thin wear layer.The results show that the peeling rate of epoxy ultra-thin anti-sliding wear layer is positively correlated with wear temperature,wear time and aggregate particle size,and the peeling rate is still less than 0.6％at high temperature and high wear time.The BPN of epoxy ultra-thin anti-skid wear layer decreases in different degrees with the increase of pollutant dis-tribution,and the influence of liquid pollutants on the attenuation of pavement anti-skid performance is more significant than that of solid sand.After 200,000 times of application,the BPN,TD and wear mass loss rate of the ultra-thin anti-sliding epoxy wear layer are excellent.
