Book Description

Several texturing experiments on heavily traveled portland cement concrete pavements in Virginia are described. Included in the experiments were textures imparted by a heavy burlap drag, metal tines (transverse and longitudinal striations), sprinkled aggregate, mortar removal, and imprinting. All textures were imparted to concrete in the plastic state. Some of the problems encountered in achieving the desired textures are discussed. Evaluations of the effectiveness and acceptability of the textures included noise, roughness, and skid resistance studies. These studies resulted in the rejection for future use of several textures for one or more reasons. A consideration of all factors gave strong indications that the transversely tined grooves spaced 19 mm (3/4 in.) on centers and the longitudinally tined grooves spaced 19 mm (3/4 in.) in combination with transverse grooves spaced 76 mm (3 in.) are preferred.
