HOT MIX ASPHALT PAVEMENT DESIGN GUIDE

bituminous concrete,hot plant mix,asphalt concrete, blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total ninety-three (93) to ninety-seven (97) percent by weight of the total mixture and are mixed with three (3) to seven (7) percent asphalt cement.

HMA Weight-Volume Terms and Relationships - Pavement Interactive

In general, HMA is made up of 3 materials: aggregate, asphalt binder and air. Typically, HMA is described by volume so it is important to know how these 3 materials relate to one another volumetrically. The animation in Figure 1 shows this both in a close-up sketch of in-place HMA (left) and a volume diagram (right) that is similar to volume diagrams seen in the geotechnical arena. Further definitions of these terms can be found below.

It is the portion of the total asphalt content that remains as a coating on the outside of the aggregate particles, and is the asphalt content on which service performance of an asphalt paving mixture depends. The formula is: be b ba P = P - ( s P 100) P (Eq. 5, Figure 1) Where: Pbe = effective asphalt content, percent by total weight of mixture.

Hot Mix Asphalt | Asphalt Calculator | Calculate Aggregate ...

Hot mix asphalt (HMA) pavement refers to the bound layers of a flexible pavement structure. Asphalt pavement material is a precisely engineered product composed of about 95 percent stone, sand, and gravel by weight, and about 5 percent asphalt cement, a petroleum product. Asphalt cement acts as the glue to hold the pavement together.
