Hot Mix Asphalt (HMA) Hot Mix Asphalt (HMA) is a blend of various sizes of aggregate particles and asphalt cement. The aggregates in HMA consist of crushed rock, gravel, or slag. These are combined in different sizes for the necessary gradation, with finer aggregates filling the spaces between larger ones to create a denser final product.

6) Use paver automation. A critical element to getting joint density is having sufficient depth of material at the longitudinal joint on the hot-side. A joint matcher provides the best opportunity to consistently place the correct depth to match the cold side. Optimal mounting location is a few feet in front of the auger.
