Colorbiotics Launches Invigorate™ Rejuvenator
BY AsphaltPro Staff
Colorbiotics, Ames, Iowa, has launched Invigorate™ rejuvenator to increase the use of recycled asphalt and extend asphalt service life. The company has long served landscaping and sports/recreation industries, and was part of the former BASF Construction Chemicals business. Now, Colorbiotics and other former BASF brands make up MBCC Group, a supplier of construction chemicals and solutions worldwide.
Invigorate rejuvenator is a new soybean oil-derived additive that triggers chemical reactions inside recycled asphalt pavement (RAP) and stiff binders to break down asphaltene aggregation and reverse the effects of oxidation in the final mix. The Invigorate additive is designed to improve the chemical properties of lower-quality binders, addressing aged elements within RAP. This new technology, developed at Iowa State University, is designed to improve recyclability of asphalt while still meeting PG and performance-testing specifications.
“With Invigorate rejuvenator, we have been able to meet specifications and increase usable RAP material to as much as 50 percent, well beyond the standard 20 to 25 percent used today,” said Dan Staebell, Colorbiotics asphalt business development manager. “That obviously has environmental and economic benefits.”
