Review Cracking Studies (Thermal and Fatigue)
When using Elvaloy® RET modifier in asphalt pavements subject to wide temperature swings or heavy loads, the modified binder's internal resilience helps absorb forces without cracking.

Review Stripping (Moisture Susceptibility)
A key to longer-lasting pavement is aggregate adhesion to the binder after repeated moisture and temperature exposures. DuPont™ Elvaloy® RET asphalt modifier helps prevent premature failure.
