2269 - Development of Alternative High Friction Surfaces for Oklahoma

Oklahoma Department of Transportation (OKDOT) would like to explore alternative surface mixtures that can provide acceptable high friction performance in critical safety locations. Pavement surface friction is measured by skid resistance (aggregate micro-texture) and surface texture (mixture macro-texture). Pavement surface mixtures are routinely dense-graded asphalt, stone matrix asphalt (SMA) or porous friction course (OGFC). The key components of this study are aggregate type and size, binder type and application, and mixture type. Since there is no standard value for pavement friction, the study will use results from Oklahoma sections on the National Center for Asphalt Technology (NCAT) Test Track as a point of reference to compare the measurements from the study. This study will provide an objective measure of friction performance for four alternative surfaces that OKDOT can review and determine if the alternative surfaces provide an acceptable level of high friction. The objectives are to develop asphalt mixtures for high friction surface (HFS) locations with regionally available aggregates and appropriate asphalt binders as alternatives to standard HFS using resin binder and calcined bauxite aggregate, and, to identify a more conventional asphalt mixture that can be placed as a 0.75-inch thin surface lift and maintain acceptable high friction characteristics.
