We experienced a full circle moment during one of our latest paving projects. All American Tire Recyclers (All American), our crumb rubber supplier, contracted Austin Bridge and Road to repave their high-traffic lot with a mix that included our SigmaBond rubberized binder! This unprecedented 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% 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% of all tire waste in Texas, All American’s lot is busy — and constantly bearing the weight of heavy equipment. 

All American needed a solution that would not only be of minimal disruption to their operations, but also stand the test of time, stress, and volume. Thanks, in part, to the workability of SigmaBond, the paving contractor completed the job in just one day! Additionally, the carbon black found in All American’s tire rubber improves to 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% tire rubber and more than 15% RAP and RAS without impacting performance. From cradle to gate — crumb rubber to liquefied tire rubber to a new pavement — Polyco and All American have brought the paving cycle full circle right in our own backyard.
