Ergon Asphalt & Emulsions and Mathy Construction Awarded Patent for Revix(TM)

Process allows for production and placement of conventional HM) at reduced temperatures of up to 75 degrees F.

Ergon Asphalt and Emulsions, Inc., (Ergon), and Mathy Construction Co. of Onalaska, WI announced today the award of a patented process that allows for the production and placement of conventional hot mix asphalt (HMA) at reduced temperatures of up to 75 degrees F. This surfactant enabled patented process which is compatible with Non-Modified, Polymer Modified and PPA containing asphalt binders was co-developed by Mathy Technology & Engineering (MTE) and Paragon Technical Services, Inc., and has been trademarked REVIX(TM). REVIX(TM) will be exclusively marketed internationally by MWV Specialty Chemicals Division's Asphalt Innovations team as MWV EVOTHERM® 3G.

EVOTHERM 3G offers many advantages over other WMA processes including significant energy savings and environmental benefits over conventional HMA. These benefits include the ability to increase RAP and RAS content due to the reduced binder aging. It can reduce emissions of organic compounds by up to 60% at the paver screed, and provide HMA contractor's energy savings ranging from 10% to 25% without physical Hot Mix Plant modifications. EVOTHERM 3G does not alter the specified SHRP PG graded binder when added compared to other WMA technologies.

Ergon and Mathy believe that EVOTHERM 3G provides workers an environmentally friendly alternative to the existing HMA and current "water only" WMA processes. This contractor friendly additive will aid in the expansion of the warm-mix asphalt category worldwide.

"We are excited to have teamed up with MWV to market this technology internationally as EVOTHERM 3G," said Baxter Burns, Executive Vice President of Ergon Asphalt & Emulsions, Inc. "This patented WMA additive greatly expands and diversifies our existing product portfolio, with readily apparent value to our customers and the infrastructure industry."

"Mathy Construction is proud to be a part of this well respected group of companies to provide a product that will help expand WMA around the country," said Steve Mathy, CEO, Mathy Construction Co. "Production of high quality HMA with lower fume exposure and consuming less energy is a true win for the industry."
