Air Blowing: Asphalt may have air infused into it if it is to be used for layer functions. Asphalt is heated to 500 Fahrenheit throughout the air-blowing process and afterwards air bubbles are compelled into the fluid for a number of hrs. This leads to the asphalt remaining in a fluid state when cooled.

The name "hot-mix" originates from the procedure of heating up the asphalt and accumulation prior to combinations to remove any kind of moisture and also obtain ample fluidity for correct amalgamation and also spreading.
