Anchor: #i1013899 Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i1013905 6.1 General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between 300-350ºF) in an asphalt plant.
The binder is then mixed at a hot mix plant with aggregate and laid with a typical asphalt paver. PG76-22GTR has to meet the same grading requirements as standard GTR asphalt, .

Rubberized asphalt concrete (commonly known as RAC) is a road paving material made by blending ground-up recycled tires with asphalt to produce a binder which is then mixed with conventional aggregate materials. This mix is then placed and compacted into a road surface.
The specified proportion of crumb rubber particle must be incorporated into the asphalt by a “dry process” in a batch type asphalt plant. The asphalt may contain glass granulate aggregate and can be manufactured using either conventional or warm mix asphalt technology.
Being the largest market for ground rubber, rubberized asphalt consumes an estimated 220,000,000 pounds or around 12 million tires annually. (That number is expected to grow) More and more states are starting to see the benefits of rubber in asphalt and recently have been taking on the old technology and mastering the process.
