TRANSVERSE TEXTURING WITH METAL TINES

The transverse texturing is done by the mechanical texturizer of the paving train which uses the edge of the freshly formed slab for alignment. This texturizer used spring steel tines four inches long, spaced approximately 1/2 inch apart, and 1/8 inche in diameter. The speed of the comb should be slow enough so that it will penetrate the surface to the required depth, yet fast enough so that the machine can keep up with the paver. The tines should be pulled across the surface as the water sheen of the fresh concrete begins to disappear. Difficulties with transverse tine grooving are discussed, and comparison is made with the normal burlap drag texture. Experience in Louisiana where the rainfall is high and hydroplaning is a major concern is reported here. This project was designed to evaluate several types of surface textures for a skid resistant pavement surface.
