Specifications, tests, and practices examine the properties of various road and paving materials and explain how to measure their characteristics. These standards address aggregates, bituminous mixtures, bridges, bridge decks, and structures. They also cover highway traffic materials, such as retroreflective sheeting and pavement markers.

Volume 04.03 also covers 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, tire and slider characteristics, traffic monitoring, and vehicle roadside communication.
