Recycling Agents/Rejuvenators

Increasing the amount of RAP in pavement construction is critical, not only for reuse of old pavements, but as a way to help reduce CO2 emissions and increase profitability.

WRI can apply renewable chemistry to wastes or natural feedstocks to produce oils (recycling agents) that are capable of softening aged reclaimed asphalt pavement (RAP) to improve circular economy of these feedstocks and recyclability of asphalt pavements. Many of these product have superior aging resistance compared to some commercial bio-based recycling agents. Some of these products can also be designed to incorporate basic nitrogen which can promote adhesion and reduce moisture stripping

WRI has also been able to successfully apply renewable carbon chemistry to chemically rejuvenate, not just soften, heavily processed and oxidized materials such as reclaimed asphalt shingles.
