Hot Mix is an engineered mixture of aggregate, or stones and sand, with liquid asphalt cement, a petroleum product. Various sizes of aggregates are heated, then mixed, in exact proportions, with asphalt cement that has been liquefied to 300 degrees. While the mixture is still hot, it is delivered to the surface and paved on the top of the base or subgrade that has already been prepared. Very soon after paving, the mixture cools and hardens, and can be driven on right away.
While this product is overused as a management tool and not environmentally friendly, it can still be an important part of a pavement management plan.
