Improving Asphalt Pavement Performance
Longer-lasting pavement
We need resilient roads. Smooth roads. Crack-resistant roads. For transportation infrastructure exposed to temperature swings and heavy wheel loads, these features are critical. Wherever longer-lasting pavement or greater smoothness and traction safety is needed, ELVALOY™ Reactive Elastomeric Terpolymer (RET) delivers.
ELVALOY™ RET creates a permanently improved bitumen-based binder, delivering long-lasting performance in well-engineered pavements – meaning it can provide a higher total value from its extended service life and reduce the need to disrupt traffic prematurely.
How has ELVALOY RET been applied?
- Smoother, longer-lasting airport runways: runways, taxiways and related pavements have been built in Mexico, Russia and the Czech Republic.
- Expressways in growing economies: key highways around the world are handling commercial and automobile traffic better and longer thanks to improved binder performance.
- Safer intersections: asphalt paving stays smoother and safer at intersections, where the forces causing rutting are often greatest.
- Damage-resistant pavement: asphalt modifier creates a better binder at the molecular level, which helps make pavements more resistant to fuels and deformation.
ELVALOY RET adjusts to your climate
Base asphalt properties vary from source to source. Local binder suppliers can pre-test their base asphalt in a lab setting, to determine optimum addition rates for ELVALOY RET. After modification, the new binder will typically meet higher performance specs.
Asphalt success stories
| Reduced Rutting in Hot Climates India's GVK Desert Zone Expressway GVK Expressway (Jaipur to Kishangarh) in the State of Rajasthan is located in a high-temperature desert zone, with sections subject to heavy traffic. |
| A Key Brasil Transportation Corridor Rodovia Anhangüera (SP-330), a 4-lane toll highway, connects São Paulo with the state's hotter northern areas. |
Reducing Cold Cracking A landing strip, ramp, taxiways and a drainage system were reconstructed using RET at Magadan Airport. |
| Challenging Canadian winters Pavements made with different modifiers were tested side-by-side in Timmins, Ontario, where winter temperatures reached 50-year lows. Fighting the causes of pavement cracks |
| Managing Hot-Cold Range Extremes Outlasting Others in a High Desert Climate Oregon "high desert" highway sections built in 1991 using ELVALOY RET outlasted all other modified binder sections, in a service environment marked by heavy truck traffic and severe temperature cycles. |
| Montana Maintenance Costs Reduced Project engineers wanted all the temperature range they could get, to fight cracking and rutting with a better-built pavement. |
These are a few of the places around the world ELVALOY RET has improved infrastructure, but we are far from finished. Let’s discuss your unique pavement challenge.
