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. |
