How long will Evotherm in asphalt remain effective at typical storage temperatures? This is one question we often get asked. To investigate, we have conducted laboratory tests by adding our additive to the asphalt, and storing it for up to 20 days at 300 F. We have found that, even after 20 days in the […]
We get asked a lot in the field about coating of aggregate under WMA conditions. As Evotherm is a great surfactant, this is never an issue. On one of my first jobs, the operator turned off the pump for a few minutes and then turned it back on, and the difference was like night and […]

Towards the end of this season, we have gotten several inquiries on how Evotherm technology can help obtain LEED credits. Evotherm chemistry comprises a surfactant package that facilitates paving at 50 F to 100 F lower termperatures than traditional hot mix asphalt paving. As such, the use of Evotherm can help contribute to certification for […]
Asphalt Rocks came together for a rare performance at the Asphalt Institute’s annual meeting last week. The band released a new hit titled, Warm Mix, featuring guitarist Everett Crews. A recent review of the band stated, Lexington’s rock-a-billy nice guys haven’t tried for a full-on do-over of their 1990 smash hit “Under the Overpass” but […]
