Pavement texture is the controlling factor in the skid-resistance level of roadway surfaces. Through a complex interaction of micro and macro textures at the pavement-tire interface, sufficient friction is needed for vehicles to perform routine maneuvers under normal operating conditions. To obtain more complete data on texture, a non-contact high-speed method was developed to permit the collection of pavement data from a vehicle moving at highway speeds. This method can be correlated with Circular Texture Meter (CTM) test procedure presented in ASTM E2157 to validate macro-texture measurements. These methods combine existing designs for the measurement of macro-texture. The correlation of macro-texture measurements with skid resistance values could allow the New Jersey Department of Transportation to estimate skid values of the pavement network while collecting pavement ride quality data for the PMS with one piece of equipment on an annual basis. This will significantly reduce the need for the ASTM E274 skid resistance trailer to collect the skid resistance data over a two year period. The screening of the states pavement network would allow detailed measurement of the pavement-tire interface with ASTM E274 skid resistance trailer.
