• Abstract:
  This report describes research into the water quality and hydraulics of the Permeable Friction Course (PFC). ; Water quality monitoring of 3 locations in the Austin area indicates up to a 90 percent reduction in pollutant ; discharges from PFC compared to conventional pavement. This reduction is the result of accumulation of ; pollutants within the pavement and the reduction in pollutants washed off of vehicles during storm events. The ; project also developed a methodology for measuring permeability of the pavement in situ. The required ; overcoming several instances where conventional assumptions in permeability measurements were violated. In ; particular, flow through the pavement at the heads evaluated was nonlinear and not consistent with Darcy’s law. ; One dimensional steady state and two dimensional dynamic models of flow in PFC were developed. The latter ; model is capable of predicting surface and subsurface flow from highways of various geometries.
