Feb 01, 2013  Asphalt concrete is a composite material commonly used in construction projects such as road surfaces, airports, waterproofing products and parking lots. Asphalt is used as a binder mixing with mineral aggregates together. In other words, asphalt acts as an adhesive between aggregates forming thin films with a thickness of about 20 to 50 μm.
