Asphalt Rejuvenators for Recycled Asphalt Pavement ArrMaz

Revive rejuvenators reduce the complex shear modulus of the resulting RAP-Virgin asphalt binder mixture. This combination reduces the risk of undesired performance and enables profitable use of more RAP. Adding an additional 20% RAP to a 15% RAP mix will allow you to reduce your virgin binder demand by almost 40%.
