Guide for Pavement Friction: Background and Research

Abstract

This digest summarizes the findings of the research conducted under National Cooperative Highway Research Program (NCHRP) Project 1-43 to develop a guide that addresses frictional characteristics and performance of pavement surfaces and considers related tire-pavement noise and other relevant issues. The research was concerned with highway pavements constructed with asphalt and concrete surfaces. Microtexture and macrotexture were both examined as they are extremely important pavement surface characteristics to the development of surface friction.
