Ultrathin Bonded Asphalt Wearing Surface 13 Pavement Defects and Failures You Should Know pavemanpro

The heavy application of the asphalt membrane seals small cracks in the existing pavement and helps to ensure the adhesion of the HMA to the underlying pavement The primary function of the ultra thin bonded wearing course is to provide a durable friction resistant surface on Small bowl shaped depressions in the pavement surface that penetrate all the way through the asphalt layer down to the base course They generally have sharp edges and vertical sides near the top of the hole Less severe depressions can be fixed by applying a thin surface patch or infrared patch Rutting Ruts in asphalt pavements are
