Skid resistance and the potential use of alternative materials for pavement wearing course: A review

One of the criteria for a well-designed road is the ability of the road to provide high initial skid resistance and to maintain it for the entire service life of the pavement. The ability of the pavement surface to provide an adequate friction when a moving rubber tire of vehicle passing through it is called skid resistance. Local readily available construction materials often do not comply with conventional pavement specifications, with a tendency to polish under traffic and to provide inadequate friction. The performance of the skid resistance of the road surface alters based on the shape, size, and gradation of the aggregate in the pavement mixture of the surface to be worn, as well as environmental and traffic conditions. The aim of this study is to address these drawbacks by reviewing prominent alternative materials that have the potential to replace standard aggregate such as granite for pavement wearing course.
