Liberty and Lehigh Sign Agreement on Rheopave RMA Technology


In a deal that should see benefits for the companies involved, Lehigh Technologies and Liberty Tire Recycling will offer the North American asphalt industry a superior solution for improving the sustainability, economics and performance of rubber modified asphalt (RMA). Under the terms of the agreement, Liberty Tire Recycling will provide sales, service and support for Rheopave RMA systems in selected regions in North America.

“Combining our companies’ capabilities enables us to broaden the reach for an important technology,” said Ryan Alleman, sales director for Lehigh. “Together we hope to make Rheopave the performance standard for RMA systems and offer solutions to segments that are currently served only by polymer-modified systems.”

Rheopave additive technology is a patented blend of polymers and other components developed specifically to enhance the performance of rubber powders in RMA systems. Extensive testing by independent laboratories has shown that Rheopave RMA systems offer superior performance attributes, including better dynamic shear rheometer and multiple stress creep recovery properties as well as improved storage stability. Rheopave RMA systems are state agency approved and are in commercial use today.

“Rubberised asphalt is longer-lasting, safer, less costly and friendlier to the environment, which aligns with Liberty Tire’s commitment to reclaim, recycle and reuse,” said Doug Carlson, vice president of asphalt products for Liberty. “Partnering with Lehigh to offer sustainable technologies like Rheopave emphasizes both Liberty Tire’s and Lehigh’s pledge to the environment.”
