In hot mix asphalt (HMA), using Elvaloy® RET can save time and money

For hot mix asphalt paving contractors, polymer-modified binder made with Elvaloy® RET can help meet higher performance specifications without creating problems for crews or worries about weather delays.  Storage-stable RET-modified binder can offer new flexibility in materials sourcing, value-engineering and project bidding strategy.

Faster Compaction

Hot mix asphalt modified with Elvaloy® RET can be compacted faster, with less sticking to equipment.  It's also more storage stable, and can be compacted at temperatures as much as 20 degrees (F) lower than SBS-modified asphalt.
An Easy-Handling Mix
Storage-stable pellets of Elvaloy® RET are easy to blend into hot asphalt, without a need for high- shear mills.  Contractors who become their own modified binder producer can gain more control of raw material costs.
Predictable Binder Performance
Predictive tests with any given asphalt help minimize polymer use to meet or exceed binder performance specs. » More about testing and processing
Less Polymer, More Freedom
With Elvaloy® RET, every molecule adds performance, enabling low addition rates. Build or buy high-performance binder more efficiently, store it longer, and ship it farther.
Also in Warm Mixes and Emulsions
DuPont™ Elvaloy® RET is compatible with most warm mix technologies, and can be used to make cationic emulsions for use in various emulsion products such as chip seals, fog seals and microsurfaces.  
Contractor Comment:

"This mix has a more workable consistency. It required no more roller passes than the 76-22 and did not need to be vibrated as hard. This mix did not push or crack when rolling."
