The Relationship Between Texture and Pavement Friction

Abstract

Abstract The transient slip method is shown to be a useful technique to evaluate the speed dependence of pavement friction. From the results of transient slip tests with a standard test tire, it is possible to predict skid resistance, speed gradients, and side force coefficients. Transient slip data can be predicted from wet pavement macro-texture and microtexture and, therefore, skid resistance-speed gradients and side force coefficients can be predicted from texture measurements.
