Portland Cement Concrete Pavement Texturing Methods
Transportation Research Record: Journal of the Transportation Research Board, 1996The testing and construction details of nine test sections with varying textural characteristics are described. The effects of the textures on the frictional and noise characteristics of the pavement surface were examined. Skid numbers were acquired according to ASTM E274 with ribbed and smooth tires at 65, 80, and 105 km/hr for all sections. Six types
