Santa Barbara County has collaborated with the CalRecycle (Department of Resources Recycling and Recovery) to repair Palamino Road in the Jesusita Fire burn zone in Santa Barbara. The pilot project will utilize 350 tons of recycled tires for the purpose. As California already recycles more than 30 million used tires a year, the CalRecycle will now mix the tire-derived aggregate (TDA) with rubberized asphalt concrete for creating quiet, long-lasting road surfaces.


Tire derived aggregate (TDA) contains shredded, used tires, and is one-third the weight of traditional soil materials. Accordingly, it exerts half the earth pressure, and provides 10 times better drainage when compared to regular road construction. The less expensive component also provides a more stable embankment for the new road surface. The TDA fill will be spread over 400 feet long, 9 to 12 feet wide, and 6 feet deep road section. The project will use 35,000 waste tires, which, otherwise, were destined to deck landfills or stockpiles for good.
