During the entire service life of pavement, the exposed surface must have an adequate level of roughness, so as to expedite the friction amongst vehicle wheels and the surface of the pavement. Therefore, the abrasion and skid resistance should be considered when measuring the wear, sliding, and skidding levels of a pavement surface. It is well-know...
