EVALUATION OF OPEN-GRADED FRICTION COURSE MIXTURE

Open-graded friction course (OGFC) is a porous, gap-graded, predominantly single size aggregate bituminous mixture that contains a high percentage of air voids. The high air void content and the open structure of this mix promote the effective drainage of rainwater, which also minimizes hydroplaning during wet weather. This characteristic also reduces splash and spray behind vehicles and improves wet weather skid resistance. Other purported benefits of this type mix are lower pavement noise and reduced roadway glare during wet weather, which improves the night visibility of pavement markings. This paper documents Louisiana's first use of this type mix since the suspension of OGFC mixes in 1984. Information is included on OGFC mix design and cost.
