THE SIGNIFICANCE OF PAVEMENT TEXTURE
The paper discusses the influence of roadway surface textures on the skid resistance, the speed-gradient, the wet-pavement accident rate, pavement wear, and the generation of tire-road interaction noise. The tendency of a vehicle to hydroplane is reduced by increasing the texture magnitude. Appropriate textures are developed by using open-graded asphalt friction surface courses and by grooving portland cement concrete with steel tines or a vibrating float while the concrete is plastic. Hardened pavements can be textured by grooving with a diamond saw or by resurfacing with an overlay. More development is needed in texture measurement techniques, especially in automating the stereo-photo interpretation method and the linear polarized laser technique.
