PERFORMANCE SURVEY ON OPEN-GRADED FRICTION COURSE MIXES

摘要: This synthesis report will be of interest to construction, maintenance, pavement design, and materials engineers, contractors, others interested in the use open-graded friction course (OGFC) mixes. It describes current state-of-the-practice on OGFC includes information regarding materials, rehabilitation strategies. Alternative treatments traditional are also identified discussed. Information for was collected by surveying U.S. Canadian transportation agencies conducting a literature search gather further North American European practices. Transportation Research Board recent performance porous asphalt identifying discussing benefits stress indicators. A new generation has evolved last five years with changes that have been reported dramatically improve OGFCs. Changes include combination empirical design adjustments, adoption innovative technologies, improved methods construction. The material use, as well applicability mixtures use.
