Raveling is loss of pavement material from the surface downward and is caused by the loss of asphalt binder (deterioration), ultraviolet exposure, traffic frequency, weather conditions, asphalt mix design, and compaction of the asphalt during construction. As the asphalt binder in the pavement wears away, the appearance starts to turn grayish from the fresh, black look of new asphalt. Also, as the binder wears away, aggregate particles begin to break away. This begins with fine aggregate particles breaking away and, consequently, exposing the coarse aggregate.
