Performance of prototype embankment built with tire shreds and nongranular soil Zornberg, Jorge G ; Costa, Yuri D ; Vollenweider, Brent

By: Contributor(s): Publication details: Transportation Research Record, 2004Description: nr 1874, s. 70-7Subject(s): Bibl.nr: VTI P8167:1874; VTI P8169:2004Location: Abstract: The mechanical response of a prototype embankment fill built with tire shreds and nongranular soil was evaluated. The test embankment consisted of three distinct sections, each 10 m (33 ft) long and 1.5 m (4.9 ft) high. Specifically, the embankment included a layered section composed of successive layers of soil and tire shreds, a soil-tire shred mixed section with 10% tire shreds by weight, and a pure soil section. The embankment was exposed to heavy-truck traffic immediately after construction. At 120 days after construction, the settlement rate in the two sections containing tire shreds converged to a rate similar to that observed in the section of pure soil. However, the section constructed with soil-tire shred mixture exhibited a better overall long-term behavior than the layered section, as it showed smaller differential settlements. The results collected in this study also provide insight into the in situ compression and compaction procedures and preparation characteristics of soil-tire shred mixtures and soil-tire shred layered systems.
