The contents of this report will be of interest to highway materials, construction, pavement management, safety, design, and research engineers, as well as others concerned with the friction and related surface characteristic

The factors that influence friction and the concepts of how friction is determined (based on measurements of surface micro-texture and macro-textur

38、e) are discussed. Methods for monitoring the friction of in-service pavements and determining appropriate actions in the case of friction deficiencies (friction management) are described. Also, aggregate tests and criteria that help attain adequate micro-texture are presented, followed by a discussi

40、.1Chapter 1IntroductionChapter 1Introduction1.1 BackgroundPavementtire friction (or, simply, pavement friction) is one of many factors determining highway safety and, in particular, the probability of wet skidding crashes. Highway agencies have recognized this fact since the 1920s (Moyer, 1959). The

41、 probability of wet skidding crashes is reduced when friction between a vehicle tire and pavement is high.Skid-related crashes are determined by many factors, wet pavement friction being only one of them. Other factors, such as road geometry, traffic characteristics, vehicle speed, driver action, an

42、d weather conditions, must be considered together with friction data when evaluating the safety of a particular section of roadway.The Guide for Pavement Friction, Guidelines for Skid-Resistant Pavement Design, published by the American Association of State Highway and Transportation Officials (AASH

43、TO) in 1976, recommended pavement specifications that would yield the desired frictional properties upon completion of construction and that would maintain adequate long-term friction. This guide discussed the importance of aggregate selection and mixture design for both asphalt- and concrete-surfac

44、ed pavements, and the role of micro-texture and macro-texture in pavement surface friction.Although much research has been conducted on pavement surface characteristics and pavementtire interactions since development of the 1976 guide, the available information is somewhat fragmented and has not bee

45、n integrated into a comprehensive, systematic approach for identifying friction needs and determining the optimum pavement strategy. Exacerbating the problem are the changes that have taken place with time, including changes in pavement construction materials and mixture design properties, construct

46、ion procedures and standards, vehicle and tire characteristics, traffic loading, and friction-testing methods and equipment.Continued introduction of new materials and technologies, coupled with the increasing focus on the needs of the highway user (safer and more comfortable roads), has placed even

47、 greater demands on highway engineers to design and build longer-lasting, cost-effective pavements. This Guide for Pavement Friction should help highway engineers accomplish such a task. 2008 by the American Association of State Highway and Transportation Officials.All rights reserved.

These recommendations are intended to supplement but not replace an agencys normal structural and/or mix design practices. The guide covers the following topics:Characteristics of pavement m
