| AASHTO Guide for Pavement Friction |
AASHTO Guide for Pavement Friction, Information is presented that emphasizes the importance of providing adequate levels of friction for the safety of highway users. The factors that infuence friction and the concepts of how friction is determined (based on measurements of surface micro-texture and macro-texture) are discussed.
AASHTO Guide for Pavement Friction
Methods for monitoring the friction of in-service pavements and determining appropriate actions in the case of friction defciencies (friction management) are described. Also, aggregate tests and criteria that help attain adequate micro-texture are presented, followed by a discussion of how paving mixtures and surface texturing techniques can be selected so as to impart the macro-texture required to achieve the design friction level.
