USE OF SHREDDED TIRES FOR LIGHTWEIGHT FILL

Shredded waste tires were used as lightweight fill to repair a landslide in a highway improvement project in southwest Oregon. Approximately 580,000 shredded waste tires were trucked to the site from four different sources 240 to 440 km (150 to 275 mi) away. The tires were placed and compacted with a dozer, then capped with 0.9 m (3 ft) of soil and a pavement section with 20 cm (8 in.) of asphalt pavement over 58 cm (23 in.) of aggregate base course. The in-place shredded tire fill cost $16.82/cu m ($12.87/cu yd), which included a significant rebate from the Department of Environmental Quality. Without the rebate, the cost would have been $35.16/cu m ($26.91/cu yd). The shredded tire fill was instrumented and monitored for 1 year following installation. Instrumentation included inclinometers, piezometers, settlement plates, and survey hubs. Falling weight deflectometer tests were also performed. The shredded tire fill compressed linearly in relation to surcharge load as the soil cap and pavement section were placed. Compression appears to be related to shredded tire fill thickness. Creep or compression under traffic loading occurred during the monitoring period. The compacted density of the shredded tires varied from 730 to 845 kg/cu m (45 to 53 pcf) at various stages of compaction and surcharging. A standard asphalt pavement with aggregate base was adequate over the shredded tire fill. The shredded tire embankment represents a softer subgrade condition than do surrounding soil embankments. However, pavement deflections were considered within acceptable limits after 20.3 cm (8 in.) of asphalt pavement was in place.
