Abstract

With the rapid development of asphalt pavement construction projects, driving safety has attracted attention. There is a certain correlation between the anti-skid ability and environmental factors. To conduct experimental research on the anti-skid performance of asphalt pavement in high temperature and high humidity environments, the anti-skid ability of four types of asphalt mixtures was quantitatively studied in temperature, humidity, water accumulation, and high temperature and high humidity coupled environments. Research has found that the anti-skid performance of high-temperature and high humidity asphalt pavement rapidly decreases. As the humidity increases, the anti-skid performance continues to decrease but at a slower rate. The degree and speed of anti-skid performance decrease between SMA-13 and SSAM-13 are basically equivalent. The results of this study can provide theoretical basis for the optimization design of anti-skid performance in road engineering in high temperature and high humidity areas.
