Elvaloy® asphalt paving additive is a "reactive elastomeric terpolymer" (RET)
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.
Proven Performance Since 1991
Technical research and field experience show how binders made with Elvaloy® RET fight rutting, stripping, thermal cracking and fatigue.
Choosing the right asphalt paving additive can save time and help meet tougher specs.
