                Scrap tires pave roads. (Cover Story) Al France. 
            Brief Summary: Jackson County, Oregon contracted with International 
            Surfacing Inc. to make an asphalt-rubber paving mixture. The 
            experimental road will be monitored yearly to determine if the 
            compound is an effective alternative for road surfacing. The rubber 
            comes from recycled and shredded automobile tires.

            When an asphalt-rubber pavement is placed on a road, does it matter 
            where the scrap tires come from that were used to produce the crumb 
            rubber? 
            Where the tires come from does not affect the quality of the rubber. 
            Rubber suppliers certify the quality of the rubber specified by the 
            pavement desig engineer. 
            But, since scrap tires are health and fire hazards, most states 
            outlaw their disposal in landfills. To avoid that, the state of 
            Oregon and Jackson County are making sure that local asphalt-rubber 
            projects use their scrap tires. 
            Oregon scrap tires were used on a 15.6-mile asphalt-rubber hot mix 
            overlay project on Butte Falls road in Jackson County last summer. 
            The county's public works department required that Oregon scrap 
            tires be used and that those tires come from Jackson County. 
            As a result, International Surfacing, Inc., Chandler, Ariz., 
            contracted with Tire Recycling Technologies, Olympia, Wash., to have 
            about 72,000 tires shredded in Jackson County. They were then sent 
            to Baker Rubber, South Bend, Ind., for further processing. 
            The state department of environmental quality (ODEQ) provided a 
            $100,000 grant as partial reimbursement for a demonstration project 
            using scrap tires, money which comes from a $1 charge to dispose of 
            old tires when buying new ones. 
            Brad Price, waste tire specialist with ODEQ, pointed out that this 
            was not the first time the state had mandated use of Oregon scrap 
            tires in similar projects. However, it was the first major 
            asphalt-rubber project. Several smaller test projects using rubber 
            from scrap tires have been completed in other Oregon counties. 
            Jackson County Engineer Dale W. Petrasek described the pavement 
            conditions of the road prior to the overlay as having numerous 
            defects. 
            "They ranged from rutting to alligator and thermal cracking," he 
            said. "It's an old territorial road going back to the 1800s that 
            hadn't seen any improvements since the '50s and '60s. We wanted to 
            put asphalt-rubber to the test and selected a road that has light 
            and heavy snowfall and elevations varying about 2,000 feet from one 
            end to the other. It also has 80,000-pound load logging truck 
            traffic on it. 
            "A three-mile conventional asphalt pavement control section will be 
            added to each end of the project next year," Petrasek said. "Our 
            pavement maintenance system will keep track of cracking, rutting and 
            other defects to monitor pavement performance over the years." 
            Using local tires in an asphalt-rubber pavement is a real good 
            promotion point around here, because people have become more 
            environmentally aware," said Jackson County Public Works Director 
            Joseph Strahl. "But it's not just getting rid of scrap tires and 
            putting them to good ultimate use. What is more importation is that 
            it allows us to use fewer natural resources. It's not just oil, it's 
            also scarce and expensive quality aggregate, it's the whole thing."
