Testing and Processing Asphalt Binders with Elvaloy® RET
Producing a higher-performing asphalt binder delivers value to contractors and project owners, and is often a key requirement for today's more highly engineered paving projects.
Pre-Testing the Reaction
The reactive component of Elvaloy® RET terpolymer has a predictable rate of reaction with a given asphalt source. Pre-testing in a lab helps optimize processing conditions.

Design of Proper Mixing
DuPont™ Elvaloy® RET is a pelletized terpolymer that needs distributive and dispersive mixing design in order to faclitate reaction with available asphaltenes.

Producing PMA with RET
The chemical reaction of Elvaloy® RET terpolymer with asphalt takes place in a heated mixing tank with gentle stirring (no high-shear mill needed). When the reaction is done, the modified asphalt binder has permanently improved properties.
