SKID RESISTANCE OF ASPHALT PAVEMENT SURFACES RELATED TO THEIR MICROTEXTURE

Well-designed and constructed asphalt pavements can provide safe and durable surfaces with high-skid resistance. Pavement surface characteristics are related to their overall longitudinal profiles that contain various wavelength ranges. The range of wavelength, shorter than 10(-3) ~ 10(-4) [m], is often referred to as a microtexture and it is related to skid resistance of the surface. Many research works have been carried out about the pavement/tire interactions, however, very few of them have dealt with actually measured microtexture including the wavelength of 10(-5) [m]. The aim of this research is to acquire precise microtextures of pavement surfaces first as longitudinal profiles using a laser type profilometer. The measurements were done for 30 [mm] at the interval of 10 [m] (=10(-5) [m]). And also, dynamic friction coefficient was measured using Dynamic Friction Tester, which was recently employed as a standard tester by ASTM. The measured profiles were analyzed using conventional FFT and PSDs (Power Spectral Density) were obtained. Finally, the relationship between the measured skid resistances and the results of the analyses were discussed. As a conclusion, the most influential wavelength range was found to be 0.01 ~ 1 [mm] from the FFT analysis.
