Pavement Texture Measurement from a Moving Vehicle
The coefficient of locked-wheel friction for a wet pavement depends on the geometrical characteristics (texture) of the road surface. Drainage depth and mean void width were selected as the best geometrical characteristics for this study of possible means of measuring pavement texture from a moving vehicle. Two devices for the measurement of drainage depth and mean void width, the light stylus and the zero-slope detector respectively, were then developed in the laboratory. Measurements were made on pavement specimens consisting of various aggregates, to evaluate the two devices. Finally, several techniques, both manual and computerized, for evaluating measured data are presented. Both devices performed successfully in the laboratory. Although no attempt was made to test either device on actual road surfaces, it was shown that transferral of these devices from the laboratory to a moving test vehicle could be made with a reasonable expectation of success.
