This leads to the asphalt staying in a fluid state when cooled down.

The name "hot-mix" comes from the treatment of heating up the asphalt and also aggregate prior to combinations to remove any kind of moisture and acquire ample fluidity for appropriate combinations and spreading. Hot-mix asphalt, abbreviated HMA, is typically utilized for high-traffic locations, such as main roadways and also freeways, whereas cold-mix asphalt, or CMA, is typically utilized for leading secondary roads.
