Abstract

Abstract: In order to study the attenuation law of skid resistance performance of asphalt pavement with thin overlay, the long-term tracking observation of the scrim force coefficient and the analysis of the attenuation change law were carried out on the asphalt pavement with AC-10 and OGFC-10 thin layer overlay. The volume index, water stability and high temperature stability were tested. The results show that, the attenuation law of the scrim force coefficient of OGFC-10 and AC-10 thin overlay asphalt pavement conforms to the Asymptotic model, showing a trend of rapid decrease first and then stability. It is recommended that "the value of stable scrim force coefficient" and "the time to reach the value of stable scrim force coefficient" should be used as the evaluation index of long-term skid resistance performance of asphalt pavement. The stability value is taken as the first evaluation index of asphalt pavement skid resistance performance, and the time to reach the stability value is the second evaluation index. Considering "the initial scrim force coefficient value", "the stable scrim force coefficient value", and "the time to reach the stable scrim force coefficient value", the skid resistance performance of OGFC-10 thin layer overlay asphalt pavement is better than AC-10 thin layer overlay asphalt pavement.
