PCC PAVEMENT TEXTURE QUALITY INVESTIGATION

A study was conducted to investigate methods of obtaining more durable skid resistant portland cement concrete pavement surfaces. The primary factors studied were curing and texturing methods, and quality of the surface mortar. The report is divided into three parts. I. Curing Compounds and Surface Hardeners. The surface hardeners tested did not show any significant effect on surface texture durability. Two of the curing compounds tested proved to be superior in performance to the older products and are now specified in State work. II. Surface Texturing Methods. Numerous texturing methods were studied in the Laboratory. The more promising ones were than tested in the field. These were: (1) a device for imparting longitudinal grooves in the plastic concrete surface; (2) a stiff bristled broom used either longitudinally or transversely; and (3) the broadcasting of various types of aggregates onto the fresh concrete surface. In addition, the pavement on one project was grooved with diamond saw blades before being opened to public traffic.
