RESEARCH PAYS OFF: TIRE SHREDS SAVE MONEY FOR MAINE

The designers of a new interchange for the Maine Turnpike were faced with weak foundation soils. The site for the 9.8-m-high bridge approach embankments on each side of the turnpike was underlain by up to 12 m of weak marine clay, offering unacceptably low safety factors for slope stability. For a cost effective solution, geotechnical designers turned to the use of tire shreds as lightweight fill. This project was the first to fully implement newly developed guidelines for limiting the heating of thick tire shred fills. Further details are provided in this article.
