Liberty Tire Recycling removes hundreds of used tires from infield of Kansas Speedway after new course construction

The NASCAR Sprint Cup teams take to the track for the STP 400 at the Kansas Speedway in Kansas City.

Liberty Tire Recycling recently removed hundreds of used tires from the infield of Kansas Speedway that were left over after the construction of a new road course at the NASCAR facility owned and operated by International Speedway Corporation. The tires had been stockpiled for use as soft walls on the road course. All of the tires Liberty Tire Recycling collected will be used as material for eco-friendly products, including crumb rubber and industrial feedstock for molded products, tire-derived fuel for industrial kilns, mills and power plants and rubber mulch for landscaping and playgrounds.

“We collect and recycle used tires from various sources throughout the country – from racetracks to tire retailers to illegal dumps – in order to create a new life for materials that would otherwise damage the environment,” said Jeffrey Kendall, CEO of Liberty Tire Recycling.

One use for recycled tire rubber that creates a natural connection between Liberty Tire Recycling and Kansas Speedway is rubberized asphalt. As a low-cost, high-performance alternative to conventional paving mixes, rubberized asphalt reduces dependency on oil and limits carbon dioxide emissions. In use for more than 40 years, rubberized asphalt has proven to reduce maintenance costs and provide a smoother, safer ride. Plus, recycled rubber provides a reliable and consistent supply of material.

“We like the idea of using rubberized asphalt in our parking lots and concourses, and we’ll continue to look for ways to use it on our skid pads to develop a test area to see how it would perform on the track itself,” said Bill Braniff, senior director of construction for ISC Design & Development, International Speedway Corporation’s in-house design and construction group.

The group used state-of-the-art computer modeling to develop track geometry that features 18° to 20° of variable banking in the turns. The previous banking at Kansas Speedway was 15° uniform banking in the turns. Construction crews removed the existing oval track asphalt pavement and re-graded the underlying soil to create the variable banking. The new road course features a layout that winds through the infield, portions of which were graded and paved as part of the road course development.
