This volume includes specifications, tests, and practices that examine the properties of various road and paving materials and explain how to measure their characteristics.



They cover aggregates, asphalt mixtures, bridges, and structures, as well as highway traffic materials such as retroreflective sheeting and pavement markers.



It also includes standards on vehicle-pavement systems, including field methods for measurement of tire pavement friction, measurement and control of roughness in construction and rehabilitation of pavements, surface characteristics related to tire pavement slip resistance, and tire characteristics.
