Even though the relationship between roadway safety and pavement frictionhas long been recognized, lack of sufficient friction at the tire-pavement interaction is still a significant contributing factor to vehicle crashes. To reduce skid-related crashes and the related fatalities on highways,optimum levels of pavement friction must be maintained under all weather conditions. Specially designed high-friction surfaces (HFS) are being more commonly considered for areas where demand for friction is high because these surfaces provide superior pavement friction without negatively affecting other surface characteristics such as noise or durability. The objectives of this paper are to review some of the high-friction surfaces available in the United States market, and contrast the performance (friction and macrotexture) of different applications in various locations. Six products used in the U.S. are contrasted in terms of performance and durability. Typical friction and texture values for the various products are presented.
