Standard Hot Mix Asphalt (HMA)
Product
Description
Standard hot mix asphalt is one or more layers of hot mix asphalt (HMA). HMA is one of the most used and durable paving materials on roads and is made by combining crushed stones (gravel and sand) with liquid asphalt cement (a black, sticky substance which is a by-product of petroleum refining).
Many of our HMA products incorporate recycled asphalt materials. By weight asphalt is one of the world's most highly recycled products.
Uses/Applications
Road surfaces are engineered structures - just like buildings and bridges - and must be designed to withstand specific weight loads, volume of traffic and weather conditions.

Additional Information
Hot mix asphalt facilities make a wide variety of different pavement mixes for specific pavement types. Hot mix asphalt facilities heat aggregates, then mix it with asphalt cement. The asphalt cement works like a glue to hold the pavement together.
