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.
