Hot-mix asphalt is made by mixing dried and
heated quality aggregates with hot asphalt cement in a mixing plant. The
required amount of each ingredient is carefully measured and mixed together
under controlled conditions to produce a uniform mixture. The mixture is
transported, placed and compacted while still hot. Specially designed paving
machines place the mixture to the required thickness and grade specifications;
after the mixture has been rolled to desired compaction density, the surface is
ready for immediate use.
