Cutting Down: Asphalt may be mixed, referred to as "reducing back," with an unstable compound that produces a product that is a lot more malleable at a minimized temperature level than austere asphalt.

Air Blowing: Asphalt may have air injected into it if it is to be utilized for layer objectives. Asphalt is heated to 500 Fahrenheit during the air-blowing procedure and after that air bubbles are pushed into the fluid for numerous hours. This causes the asphalt continuing to be in a liquid state when cooled down.
