Recycled Tire Rubber Comes Full Circle with SigmaBond

Louisiana-based Polyco experienced a full circle moment during one of its latest paving projects. All American Tire Recyclers, its crumb rubber supplier, contracted Austin Bridge and Road to repave their high-traffic lot with a mix that included Polyco’s  SigmaBond rubberized binder. This opportunity solidified our partnership as we move toward greener, more sustainable infrastructure.

The 2,200 tons of mix used on this three-acre lot contained 100 tons of PG70-22XR and approximately 18 percent tire rubber, which equates to roughly 18 tons of rubber and more than 2,000 recycled tires.

As a 24/7 plant that processes 18,000 tires a day, 6.5 million tires a year, and 26 percent  of all tire waste in Texas, All American’s lot is busy — and constantly bearing the weight of heavy equipment.

All Americans needed a solution that would not only be of minimal disruption to their operations, but also stand the test of time, stress, and volume.

The workability of SigmaBond allowed the paving contractor to complete the job in just one day.

Additionally, the carbon black found in All American’s tire rubber improves the long-term performance of the pavement — retaining its dark color and resisting cracking for a longer period of time.

This performance comes with the added benefit of sustainability. SigmaBond is capable of including up to 40 percent tire rubber and more than 15 percent RAP and RAS without impacting performance.

From cradle to gate — crumb rubber to liquefied tire rubber to a new pavement. Working together, Polyco and All American have brought the paving cycle full circle.
