Open graded asphalt concrete friction coarse

WebOpen-graded friction course (OGFC), also called permeable friction course (PFC), is a thin and permeable asphalt concrete whose skeleton is composed mainly of coarse aggregate, leading to an immediate drainage of water and an adequate frictional resistance, thus reducing traffic accidents and improving driving environments on rainy days. WebThis synthesis will be of interest to construction, maintenance, pavement design, and materials engineers, pavement contractors, and others interested in the use of open-graded friction courses (OGFC) as an asphalt concrete pavement wearing surface. Information is provided on performance benefits and limitations of OGFC, material and mixture …
