Invigorate Asphalt Rejuvenator from Colorbiotics 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.

  • Improves the chemical properties of lower-quality binders, addressing aged elements within RAP
  • This new technology, developed at Iowa State University, improves recyclability of asphalt while still meeting PG and performance-testing specifications
  • When using high percentages of RAP, Invigorate rejuvenator makes the asphalt more flexible while maintaining its durability and rut resistance
