GUIDELINE FOR TEXTURING OF PORTLAND CEMENT CONCRETE HIGHWAY PAVEMENTS

The procedure suggested for producing a durable surface texture in concrete pavements involves transverse plastic grooving. Experience to date indicates that this method is far superior to traditional methods of texturing. An advantage of plastic grooving is the reduction in the need for fine surface finishing and therfore the elimination of excessive passes with the tube float or other finishing devices. In order to improve the fine texture between grooves, one pass with burlap drag should be made in the longitudinal direction prior to plastic grooving. At the present stage of development, the comb utilizing tines appears to offer the most practical method for producing plastic grooves in concrete pavements. Grooves should be formed perpendicular to the centerline of the pavement and closely follow a straight line. Plastic groove spacing should average approximately 1/2 inch (1.27 cm). Width of groove should be 0.08 to 0.13 inch (0.203 to 0.203 to 0.320 cm) and depth from 1/8 to 3/16 inch (0.318 to 0.476 cm). Pavements subject to excessive wear (i.e., exposure to studded tires or other abnormal wear) or heavy rainfall should be plastic grooved to the maximum practical depth. Plastic grooving should be applied on all mainline pavements and ramps where high speed and rapid acceleration- deceleration are required.
