Evotherm® Warm Mix

Asphalt industry professionals trust Evotherm for three simple reasons:

Evotherm is easy to use.

Evotherm requires no equipment changes at the plant or job site. Evotherm is metered into existing materials and drops into existing HMA job mix formulas.

Evotherm requires the lowest temperatures.

This reduction in temperature expands the area a plant can service - broadening markets without compromising quality.  At the plant, Evotherm lessens the wear and tear on hot-mix equipment due to its lower processing temperatures. On the job site, traffic is returned immediately after compaction.

Evotherm delivers proven performance.

Workability and compaction at reduced temperatures are easier than HMA, especially for coarse mixes and polymer modified asphalts. Evotherm binder performance matches or surpasses the qualities found in new hot-mix asphalt and allows higher percentages of recycled asphalt (RAP) to be used.

Performance Testing and Evaluation

• The National Center for Asphalt Technology's Pavement Test Track, based at Auburn University, is broken into 200 foot test sections designed to test performance of certain asphalt mixes.  Evotherm is being tested on the track in sections E9 and E10. Read more. 
• Results of the lab and field studies demonstrate that Evotherm can produce asphalt pavements with equal or greater durability than pavements constructed with conventional HMA technology (April 2009). Read more.
• In a report prepared for the California Department of Transportation and the University of California Pavement Research Center, the performance of warm-mix asphalt was compared against traditional hot-mix using the Heavy Vehicle Simulator to assess rutting behavior. Read more.
• The Virginia Department of Transportation conducted three trial sections of pavement using warm-mix asphalt technologies. The sections were evaluated over a two-year period to assess performance of warm-mix compared with traditional hot-mix asphalt. Read more.

100 degrees Fahrenheit or more below the hot-mix asphalt temperatures is possible with warm-mix asphalt technology.		Evotherm mixes are odor free and have been found to reduce job site emissions by 40-80 percent.
Evotherm produces lower temperatures, which mean greatly reduced fumes.		Pictured above is an Evotherm paving job site in France.
