Tire Derived Aggregate

A case history is reported in which tire-derived aggregate (TDA) was successfully applied to reduce the weight of fill upon a cut-and-cover railway tunnel. Subsequent three-dimensional numerical analyses are used to explore the effect of different assumptions about the constitutive model of the TDA material. Alternative dispositions of TDA around the tunnel section are also examined. Reductions of up to 60% in lining bending moment may be achieved. For the case analyzed, the elastic description of the TDA has little influence on tunnel lining loads, although it is important for fill settlement estimates.
