Where Does Elvaloy® RET Improve Pavement Performance

Where Does Elvaloy® RET Improve Pavement Performance

The asphalt modifier, DuPont™ Elvaloy® RET, creates a permanently improved bitumen-based binder that delivers long-lasting performance in well-engineered pavements.

Polymer Modified Asphalt Information for Engineers/Specifiers

Polymer Modified Asphalt Information for Engineers/Specifiers

Tests show that polymer modified asphalt made with Elvaloy® RET can help fight the four main ways pavement often fails: rutting, stripping, cold cracking and fatigue cracking.

Fatigue Cracking | Technical Information

Fatigue Cracking | Technical Information

Asphalt can be made more resistant to thermal and fatigue cracking by increasing binder flexibility and internal resilience at a molecular level. Elvaloy® RET is a reactive terpolymer that "locks in" the extra performance needed for longer wear and wider temperature tolerance.

Anti-Strip Resistance | Properties of Asphalt Binder

Anti-Strip Resistance | Properties of Asphalt Binder

In lab settings and on real projects, paving experts are observing reduced moisture susceptibility and resistance to stripping for binders modified with Elvaloy®.

Thermal Cracks | Technical Information

Thermal Cracks | Technical Information

By creating a more resilient binder at a molecular level, DuPont™ Elvaloy® RET asphalt modifier can help prevent thermal cracks.

RET vs. SBS Modified Asphalt | Technical Information

RET vs. SBS Modified Asphalt | Technical Information

Extensive test data is available from government agencies, asphalt materials experts and universities, showing Elvaloy® RET to be at least equal, but in most cases superior in performance to SBS-modified asphalt meeting a similar specification grade.

Reactive Polymer | Technical Information

Reactive Polymer | Technical Information

As a reactive polymer, Elvaloy® RET asphalt modifier "locks in" improved binder performance.

Pavement Rutting | Technical Information

Pavement Rutting | Technical Information

Tests confirm less pavement rutting with RET-modified binder with DuPont™ Elvaloy® RET asphalt modifier.

Preventing Pavement Cracks | Technical Information

Preventing Pavement Cracks | Technical Information

By creating a more resilient binder at a molecular level, DuPont™ Elvaloy® RET asphalt modifier can help prevent cold and thermal cracks.

Multiple Stress Creep Recovery

Multiple Stress Creep Recovery

Multiple stress creep recovery (MSCR) testing helps predict rutting.

Modified Binder Information

Modified Binder Information

For asphalt terminals wanting a fast, easy way to supply modified binder, DuPont™ Elvaloy® RET reactive elastomeric terpolymer can be a smart, profitable choice.

Hot Mix Asphalt Information for Contractors

Hot Mix Asphalt Information for Contractors

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

Bending Beam Tests | Asphalt Fatigue Cracking

Bending Beam Tests | Asphalt Fatigue Cracking

Bending beam tests demonstrate cold-temperature performance.

Asphalt Binder Information for Producers and Terminals

Asphalt Binder Information for Producers and Terminals

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.

How Does Polymer Modified Asphalt Made with Elvaloy® RET Work

How Does Polymer Modified Asphalt Made with Elvaloy® RET Work

Polymer-modified asphalt made with DuPont™ Elvaloy® RET reduces rutting and fatigue cracking, fights cold cracking, resists stripping and offers "locked-in" enhancements.

What Is Elvaloy® RET Pavement Asphalt Additive

What Is Elvaloy® RET Pavement Asphalt Additive

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.
