AN INVESTIGATION OF THE DURABILITY OF THE SKID RESISTANCE OF WIRE COMBED PCC PAVEMENT SURFACES
This report involves pavements constructed with the following textures: AstroTurf Drag, Gomaco Roll-A-Groove, wire combs with 5" tine lengths with 1/4" and 1/2" tine spacings, 4" tine lengths with 1/4", 1/2", and 3/4" tine spacings, 3" tine lengths with 1/4" tine spacings, and 3" tine lengths with 1/2", 3/4", and 1" tine spacings both with and without a burlap drag preceding. Nominal wire tine dimensions of .0625" in width and .028" in thickness were used. One project had a nominal wire tine width of .125" as a variable. Under a previous study, which was incorporated into this report, the following textures were constructed: burlap drag, heavy nylon bristle broom, fine nylon bristle broom, natural bristle broom, and wire comb with 3" tine length and 1/4" tine spacing. Included in the is report is a brief description of each project and summaries of friction tests, sand patch texture depth tests and sound level measurements. The 1/4" and 1/2" wire comb textures are more suitable than the burlap drag, AstroTurf Drag, and broom textures, however, the 1/2" wire comb provides only a slight advantage over the 1/4" wire comb. Monitoring of the skid resistance and texture depths is being continued on wire comb textures. /FHWA/
