  • Evaluation of Methods for Pavement Surface Friction ...

    Pavement friction is important for maintaining safe driving on highways, particularly on horizontal curves, ramps, intersections, and elevated surfaces. Traditionally, pavement friction has been measured using a locked-wheel skid tester (LWST), but this approach has some known limitations, particularly testing on curves and short roadway segments.
