WebThis type of mixture is defined in TxDOT Specification Item 342 as a surface course of a compacted permeable mixture of aggregate, asphalt binder, and additives mixed hot in a mixing plant. Recent research addressed important design, construction, and maintenance issues associated with PFC, which has been increasingly employed by TxDOT. WebMixes typical of this structure are the permeable friction course, generally called “Open Graded Friction Course” (OGFC) and asphalt-treated permeable bases. Because of their open structure, precautions are taken to minimize asphalt drain-down by the use of fibers and/or modified binders.
