HOT MIX ASPHALT WHAT IS HOT MIX ASPHALT? Hot mix asphalt may be referred to by several names. In different sections of the state it may also be referred to as 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
There are two main types of asphalt: straight-run asphalt (asphalt cement) and air-blown asphalt (oxidized asphalt). Straight-run asphalt is used for paving roads, airport runways, and parking lots. Because of its solid to semi-solid nature, it must first be cut with a solvent to bring it to a more liquid state. This is known as cut-back asphalt.

Test Method 2 – Reclaimed Asphalt Pavement (RAP) and Reclaimed Asphalt Shingles (QC) is defined as all activities required for the production of Hot Mix Asphalt (HMA) that meets all specification requirements. The Producer shall incorporate a Quality Control system • Loader Operator/Truck Driver feeding HMA Plant
various test equipment, test methods, and criteria. The criteria are dictated by the traffic, environment (climate) and structural section of a particular pavement site. The Superpave system has resulted in huge savings. The Superpave system is applicable to vir gin and recycled, dense- graded, hot mix asphalt (HMA), with or without modification.
Batch plants, which produce HMA in individual batches, tend to be smaller-volume output plants than drum mix plants. However, they offer greater flexibility in the amounts of a particular mix they can produce, the variety of materials that can be incorporated into one batch, and their ability to produce small batch sizes.

Sale price is the market price charged for each transaction when asphalt is sold by the plant. This price varies depending on the asphalt blend and does not include transportation to the job site. To begin understanding the relationship these three drivers have with each other, it is common to begin with a break-even analysis.
