More than 30 people attended the August 15 Recycle Wisconsin: 2012 event highlighting applications and benefits of rubberized asphalt. Sponsored by Liberty Tire Recycling, the event was held at the Modified Asphalt Research Center (MARC) at the University of Wisconsin-Madison and included a tour of the campus MARC lab
“With a renewed focus on community improvement through sustainable sourcing, rubberized asphalt and other innovative applications for recycled rubber create a win-win situation for cities across the nation,” said Jeffrey Kendall, CEO of Liberty Tire Recycling. “Reusing scrap tire rubber for infrastructure like highways can help ensure that dangerous tire piles are a thing of the past, and also help build a sustainable future across Wisconsin and the nation.”
The sessions covered topics including “Sustainable Asphalt Pavements: An Industry Perspective,” “End of Life Tires in Wisconsin,” “Wisconsin Experience with Rubber” and “Rubberized Asphalt,” which provided an overview of the advantages of rubberized asphalt, from enhanced safety and reduced tire noise to better crack resistance and cost savings.
Liberty Tire reports that rubberized asphalt is a low-cost, high-performance alternative to traditional paving mixes that reduces dependency on oil and limits carbon dioxide emissions. Added to traditional asphalt, crumb rubber comprises 8% to 22% of the binder and increases tensile strength. For more than 40 years, rubberized asphalt has proven to diminish maintenance costs and provide a smoother, safer ride. Plus, recycled rubber provides a reliable and consistent supply of material.
