INFORMATION & IDEAS
The asphalt modifier, DuPont™ Elvaloy® RET, creates a permanently improved bitumen-based binder that delivers long-lasting performance in well-engineered pavements.
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.
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.
In lab settings and on real projects, paving experts are observing reduced moisture susceptibility and resistance to stripping for binders modified with Elvaloy®.
