Open-Graded Friction Course: State of the Practice;Transportation research circular

摘要

This circular summarizes the results of a survey conducted by the National Center for Asphalt Technology (NCAT). Prithvi S. Kandhal and Rajib B. Mallick were the investigators on the project. It is published in this Circular because Transportation Research Board Committee A2D03, Characteristics of Bituminous-Aggregate Combinations to Meet Surface Requirements, reviewed the information and determined it provides up-to-date information on the use of opengraded friction courses (OGFC) for applications where providing a high level of surface friction is important for the safety of the motoring public. The committee recommended wide distribution of this information by TRB. This Circular describes the current state-of-the-practice and should be of interest to pavement designers and others responsible for selecting the materials to be used in particular roadway applications.
