How to Process Reactive Elastomeric Terpolymer

Compared with other asphalt modifiers, Elvaloy® RET is typically used in smaller amounts, with gentler mixing and reduced worry about separation. » Handling and equipment
Pre-Testing the RET Reaction
Easy-handling pellets of Elvaloy® RET can be pre-tested in a lab to predict the mixing time and modified binder properties achieved with a given base material.  » Testing the addition rate

Modified Binder Chemistry
With Elvaloy® RET, improvements in modified binder performance don't settle out, or evaporate, or fade, or wear off with age. The terpolymer chemically unites with asphalt, creating a permanent change at the molecular level. » Reaction chemistry
