Abstract:

When vehicles operate at high speeds over wet pavements there is a tendency for the water to impede intimate contact between the tire and pavement. The resulting loss of friction can result in loss of control of the vehicle, and is referred to as hydroplaning. A porous surfacing over the pavement permits water to drain laterally and vertically away from the wheel path, resulting in a much reduced hydroplaning potential. The design, construction, and performance of porous asphalt surfacings is discussed with regard to the use of these surfacings on airfield pavements. These surfacings, commonly referred to as Porous Friction Surface PFS, are open graded asphaltic concretes that permit water to drain through them onto an underlying impervious layer and thence laterally to the pavement edge.
