The primary use of asphalt mix is to create pavement for roadbuilding.Asphalt pavement consists of a highly controlled mixture of liquid bitumen, filler and aggregate that is placed and compacted to create a smooth surface designed to facilitate vehicular and pedestrian transportation. The manufacture of asphalt pavement requires the combination of a number of aggregates, sand, and a filler (such as baghouse fines) or cement, limestone, etc., in the correct proportions, which is then heated and finally coated with a liquid bitumen binder. Equipment for the production of asphalt pavement asphalt mixing, bitumen melting and road maintenance equipment has been a specialization for Alltech Group.
