How Does Polymer Modified Asphalt Made with Elvaloy® RET Work



Reduces Pavement Rutting

Repeated heavy loads can cause asphalt pavements to permanently deform over time, most noticeably forming unsafe ruts in a travel lane or intersection. 

Resists Pavement Rutting

Fights Cold Cracking

Even when formulated to resist rutting in hot weather, an RET-modified asphalt enables use of paving materials that are less brittle in cold temperatures.

Preventing Pavement Cracks

Reduces Fatigue Cracking

Elvaloy® RET improves pavement resilience at the molecular level, to better resist cracking after repeated fatigue.

Improves Fatigue Life

Resists Stripping

An Elvaloy® RET-modified binder has improved adhesion to the aggregate, and thus stays coated longer, even through repeated freeze-thaw cycles.

"Locked-In" Enhancements

Hydrocarbon chemistry development results in a reactive terpolymer imparting permanently enhanced elastomeric properties in an asphaltic cement.
