Additional Information / Summary:

This National Cooperative Highway Research Program Report 37 remains as one of the major references on this topic. It reviewsthe state of knowledge on pavement skid resistance and discusses the causes of slipperiness, the mechanism of tire-road friction, and road friction measurement techniques. Based on a thorough review and evaluation of past research and experience, recommendations are made for minimum tenative skid-resistance values.
