ABSTRACT

In this research, the attenuation characteristics of skid resistance of Yangyan Road was investigated by on-site test and laboratory loading system. Firstly, by employing the Dynamic Friction Tester, the skid resistance of Yangyan road in Beijing for three years were tested to anlyze its attenuation characteristics of skid resistance. Secondly, its service process was simulated in the laboratory by the one-third scale Model Mobile Load Simulator (MMLS3), while conducting the skid resistance test for the corresponding service time of on-site anti-skidding test to compare attenuation characteristics between the laboratory and on-site skid resistance. The research results showed that the skid resistance of Yangyan Road presented a logarithmic function attenuation trend with the increase of service time. The skid resistance of the asphalt mixture slightly increased to the peak value during the three months of the simulated service period, before presenting a logarithmic function attenuation trend. The attenuation rate of the skid resistance in the laboratory test was significantly smaller than that of on-site test due to effects of environmental factors on the actual roads during their service.
