Field Data–Driven Machine-Learning Approach for Estimating Pavement Skid Numbers from LWST Measurements for Improved Asphalt Pavement Safety

Abstract

Abstract This study investigated the feasibility of predicting skid numbers (SNs) measured by a locked-wheel skid trailer (LWST) using more-accessible surface friction and texture data from a dynamic friction tester (DFT), British pendulum tester (BPT), ... Practical Applications Accurately measuring pavement friction is crucial for maintaining roadway safety, but traditional methods, such as locked-wheel skid trailer (LWST) testing, are time-consuming, expensive, and require traffic disruptions. This study ...
