Lehigh, Rheopave collaborate on rubberized asphalt technology

Comments Email

ATLANTA (April 10, 2014) — Lehigh Technologies Inc., a manufacturer of micronized recycled rubber powders, and Rheopave Technologies L.L.C., a producer of asphalt additive technologies, are partnering to create a technology they say will reduce the cost, boost the performance and improve the sustainability of modified asphalt systems.

The new product line combines Lehigh’s MicroDyne micronized rubber powders (MRPs) with Rheopave’s suspension additives, according to a Lehigh press release. Lehigh will provide sales, supply chain and distribution support through its existing network alongside its MicroDyne products, and Rheopave will provide technical support through AWI, its affiliated laboratory.

Pat Keating and Prem Naidoo, co-owners of Rheopave, developed their patented composite technology specifically to enhance the performance of rubber powders in rubber-modified asphalt, Lehigh said. Extended testing by independent laboratories demonstrated that the combination of MicroDyne MRPs with Rheopave technology provides superior performance characteristics in rubberized asphalt, the company said.

MicroDyne MRPs and Rheopave’s binders have been approved for use in hot-mix asphalt paving applications by the Florida Department of Transportation and other state agencies, according to Lehigh.

Titan International and the United Steelworkers union have petitioned the U.S. International Trade Commission and U.S. Department of Commerce seeking relief from OTR tire imports from China, India and Sri Lanka. What’s your opinion?

I wholeheartedly support their action – something needs to be done.

I think it’s a bad idea that could inevitably tie the hands of domestic tire makers.

I oppose any duties against tire importers—they only raise costs for distributors and make it harder to obtain inventory.

I’m kind of on the fence and not sure what’s right, but need more information before deciding.

I don’t really care whether or not relief is granted.
