For Polymer Modified Asphalt That Delivers Maximum Service Life
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.
Resists Rutting
Repeated heavy loads can cause asphalt pavements to permanently deform over time, most noticeably forming unsafe ruts in a travel lane or intersection.
» Avoid rutting
Fights Temperature Cracking
One of the principal reasons for considering a polymer-modified asphalt (PMA) is to enable the use of paving material that can resist cold cracking and yet still remain resistant to rutting.
» Fight thermal cracks
Postpones Fatigue Cracking
Because Elvaloy® RET adds to pavement resilience, modified asphalt can better fight fatigue cracking.
» Longer road life
Reduces Binder Stripping
Aggregates are easy to coat using binder made with Elvaloy® RET, and remain strongly bonded after moisture and freeze-thaw exposure.
» Durable adhesion
Storage Stable, Shippable
The locked-in performance properties of binders made Elvaloy® RET result from the polymer's fluid-state reaction with asphalt. Source, store and ship polymer-modified asphalt strategically to meet local project requirements.
» How Elvaloy® RET is made
The Easy-Working PMA Mix
Contractors report smooth spreading, easy hand-working and faster, problem-free compaction of asphalt mixes made with RET-modified binder.
» Easy to work with
Less Deformation
from Repeated Stress
from Repeated Stress
Pavement deformation results from accumulated unrecovered compliance from repeat stresses on the binder.
Hesp Research Group Ranks Elvaloy® RET #1
The Hesp Research Group at Queen's University, Canada, has ranked Elvaloy® RET as best performer in low-temperature pavement trials conducted for Highway 655.
Proven Worldwide
Paving experiences, test results, and expert papers show wide acceptance of RET performance benefits.
