Development of Laboratory Procedure for Measuring Friction of HMA Mixtures - Phase I

Pavement friction during wet conditions continues to be a major safety concern for pavement design and maintenance. The skid resistance of pavements is commonly measured using ASTM E 274, Skid Resistance of Paved Surfaces Using a Full-Scale Tire. However, there are no standard test procedures for evaluating the friction of a hot mix asphalt (HMA) wearing course during the mix design process. The objective of this study was to design and build a prototype laboratory device and develop tentative laboratory procedures for evaluating the wet friction and/or aggregate polishing characteristics of HMA mixtures.
