SURFACE FRICTION RESULTS ON TEXTURED PCC PAVEMENTS. FINAL REPORT
In May, 1976, the decision was made to use several different methods for creating textured surfaces on a new section of I-35 in Lyon County, Kansas. Five textures were constructed: burlap drag; wire tine finish, wires spaced 0.5 inch; wire tine finish, wires spaced 1.0 inch; bristle broom moving across pavement; and astro turf moving across pavement. Also in 1976 a new section of US-54 in Kingman County, Kansas, was constructed with four textures (as above except for bristle broom). The goal was to determine which texture techniques would best enhance the effort to provide a high friction surface, and at the same time minimize the collection of water in the tire path. It was concluded from the results of these studies that there is not sufficient benefit to surface friction from special texturing to warrant the added cost estimated at $600 per mile of 24 ft wide pavement. The burlap drag texture is done anyway and this involves no added cost. The surface friction from the burlap drag was lower initially but since there was much less change when exposed to traffic, the performance after eight years or more was very satisfactory. The larger change in surface friction for each of the other textures indicates that the initial roughness wore off more rapidly when exposed to traffic. The increased wear may also contribute to salt induced deterioration through exposure of aggregate in the pavement. The irregular surface is more difficult to seal at the centerline, shoulder and contraction joints which may also contribute to increased water infiltration.
