Elvaloy® RET Asphalt Modifier

Polymer Modified Asphalt for Better Roads

DuPont™ Elvaloy® RET reactive elastomeric terpolymers are used for polymer modified asphalt to help build roads that last longer or take higher loads without rutting.

DuPont™ Elvaloy® RET is supplied as free-flowing pellets that melt into hot asphalt to create a permanently modified asphaltic (bitumen) binder. An RET-modified asphalt remains easy-to-use, but delivers improved long-term resilience and climate resistance.

Unlike elastomeric additives that are merely mixed or suspended in asphalt, RET locks itself in during a fluid-stage reaction. The enhanced binder stays homogenous, with good aggregate coating and adhesion performance.
