Bridge approach settlement and heave-related movements create a bump in the road between bridge decks and approach, which can be so large as to make it unsafe to drive. A proactive attempt to employ sound engineering principles for the design, specification, and construction of approaches is often lacking. As a result, it is essential to employ appropriate mitigation techniques to lessen the approach settlements in order to guarantee safe travel conditions and cut down on costs associated with repairs and maintenance of the bridge approaches. One of the mitigation techniques to control bridge approach settlement is by using controlled low-strength material (CLSM). Few past studies suggest that CLSM, as a low-strength, and lightweight fill, can be used for bridge approach filling material. However, parametric investigation of various CLSM mixes in terms of reducing bridge approach settlement, thereby reducing bump near bridge approaches, is not available in the literature. In this study, to mitigate bridge approach settlement, a wedge-type CLSM fill is proposed adjacent to the bridge abutment, which is typically a lower compacted zone. To evaluate the performance of bridge approach with wedge type CLSM fill, laboratory studies and numerical analyses have been employed. The design mix for CLSM material has been done and its various properties are evaluated. Further, a bridge approach has been modeled using the finite element (FE) tool, and the settlement studies have been conducted with and without CLSM wedge, and the responses are presented.
