摘要：	In 2009, the Kansas Department of Transportation entered into an agreement with the Federal Highway Administration to fulfill the requirements of the High Friction Surface Materials Enhancing Safety at Horizontal Curves on the National Highway System project. Four locations were chosen in Kansas, two on existing asphalt pavement and two on concrete pavement. The applications on asphalt were on highway segments and the concrete segments were medium to high volume ramps at two separate interchanges. Traffic volumes ranged from approximately 1,000 vehicles per day to 25,000 vehicles per day. In general, the surfaces are performing poorly; one of the lower trafficked surfaces, an asphalt application, failed in less than three years. The surfaces on the two applications on concrete are peeling off and skid resistance numbers are dropping.
