This paper reports on developmental work to produce a porous, durable, low maintenance surfacing for concrete pavements, having the properties of low traffic noise, high skid resistance, and negligible risk of hydroplaning. Concrete pavements have been used extensively in the highway network of New South Wales for several decades. Various surface treatments and finishes have been applied to the plastic concrete to influence the surface characteristics associated with safety against skidding, tyre/road noise and, to a lesser extent, ride quality. Current practice in noise sensitive urban areas is to use open-graded asphalt as the surfacing on concrete pavement. This paper reviews an experimental approach to develop a new concrete pavement surfacing in the form of a no-fines concrete wearing layer. The research objective is to produce a porous surfacing having a long life with low maintenance cost, using high performance cementitious material.
