Comparison of Texturing Methods used for Highway Construction and Maintenance

The primary purpose of pavement surface texture is to provide adequate tire/pavement surface friction for expected conditions. Improving surface friction is a proven method to reduce wet-weather crashes and total vehicle crashes. Pavement surfaces must provide enough roughness and skid resistance to allow vehicles to travel safely during wet weather events. Diamond grinding, shot blasting, grooving, tining, burlap dragging and adding wearing courses are all methods of restoring or adding surface friction to pavements. A pavement's surface texture is made up of two components, referred to as micro texture and macro texture. Micro texture is the pavement's texture with a wavelength (distances from bumps to dips) of less than 0.5 mm and the macro texture is the pavement's texture where the wavelength is between 0.5 mm to 50 mm. Determining to what extent each of these methods increases the pavement's micro texture and macro texture (surface friction) will aid in determining which methods may increase the safety of the roadway the most. To test texture and skid resistance of pavement surfaces, several different methods are available. The Department currently utilizes a locked wheel tester, "skid truck", to measure surface resistance during wet conditions (ASTM E274/E274M). The Department also uses an Automatic Road Analyzer (ARAN) to measure the texture depth. Other options for testing surface texture are a Circular Texture Meter (CT Meter), a Dynamic Friction Tester (OF Tester), the "Sand patch" test and an Outflow Meter. Both a CT Meter and OF Tester are available for loan through the Federal Highways Administration (FWHA) Friction, Texture, and Profile Measurement Equipment Loan Program at no charge. Using this equipment, it may be possible to adequately compare different methods for increasing surface texture and determine the most effective way of improving the safety of Arkansas roadways.
