Geotechnical investigation of the potential use of shredded scrap tires in soil stabilization. Final report
Silt-tire and clay-tire mixtures, containing 0% to 100% shredded tire material by weight, with tire chips ranging in size from 7mm--13mm, 13mm--25mm, and 25mm--38mm, were tested for a series of engineering properties including compaction characteristics, permeability, unconfined compressive strength, friction angle, cohesion, and compression index. In addition, the leachate samples from shredded tire material, soil-tire mixtures, and a test embankment, containing 70% clay and 30% shredded tire material by weight, were analyzed for chemical composition. The results show that density and unconfined compressive strength decrease, and permeability increases, with increasing shredded tire content for both soil types and all three tire sizes used in the study. In general, the addition of shredded tire material improves the friction angle for both silt and clay by a few degrees but also increases their compression index values. The results of leachate analyses show that concentrations of trace elements from soil-tire mixtures are less than the maximum allowed contaminant levels specified in United States Environmental Protection Agency`s regulations.
