ed asphalt is a mixture of aggregates (stone and soil) and ed bitumen. The bitumen is ed by an innovative process, harnessing the usually undesirable reaction which occurs when hot bitumen is contaminated with water. In order to mix bitumen with road-building aggregates, you first need to considerably reduce the viscosity of the ...
