What happens to old car tires? Pennsylvania has recycled nearly 26 million of them in the last eight years, but there are millions more to go.

Penn State's Center for Dirt and Gravel Road Studies is helping to lighten the load. With a grant from the Department of Environmental Protection, the Center, under the direction of Kevin Abbey, is baling old waste tires to use as fill for rural roads across the Commonwealth.

Learn how roads are made of rubber, improving environmental conditions and decreasing maintenance costs by watching this online video or view a slide show of this new method of recycling waste tires.
