Determining Pavement Skid-Resistance Requirements at Intersections and Braking Sites.

摘要

The report covers an experimental program aimed at developing procedures for determining pavement skid resistance requirements for safe operation of motor vehicles for given roadway and traffic conditions. Instrumentation was developed and field tested for measuring acceleration values of vehicles at highway sites and procedures developed and their feasibility demonstrated for converting the measured longitudinal accelerations at intersection and braking sites to relative skid resistance requirements. The limited study of cornering maneuvers indicated that more information is needed about the relationships between lateral accelerations and pavement surface characteristics to permit development of procedures for determining skid resistance requirements for highway curves.
