WebOregon began using open-graded hot-mix asphalt concrete mixtures on its roadway system in the late 1970s. Because of the excellent performance of these early jobs, open-graded hot-mix asphalt concrete has become the preferred choice for a surface course on many of Oregon's highways. To assess the performance of the open-graded mix, a … Web(OBC) for Open-Graded Asphalt Concrete. Three asphalt types (PG 64-10, PG 64-28 PM, and asphalt rubber [AR]), three aggregate types (Sacramento, Watsonville, and San Gabriel) and three gradations (coarse, fine, and middle) that comply with Caltrans specifications of binder and the 1/2 in. OGFC gradation and aggregate quality were used … 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. philips 242e2fe review
