Recommendations for the Design of Spread Footings on Soils to Support Highway Bridges
Recent FHWA national surveys revealed that (a) state departments of transportation (DOTs) have safely and economically constructed highway bridges supported on spread footings bearing on competent and improved natural soils and engineered granular and MSE fills and (b) that many state DOTs may be missing an opportunity to save time and costs by not actively considering spread footings to support highway bridges. The goal of this paper is to promote the consideration and use of spread footings on soils when appropriate to support bridges. Perceived obstacles in using spread footings are identified, and recommendations to address these obstacles are presented in this paper. The main concern of state DOTs that do not consider spread footings is excessive settlement of bridges. This paper outlines a rational procedure for settlement analysis of bridges supported on spread footings bearing on soils. This procedure and the results of the national surveys demonstrate that spread footings bearing on soils can perform very well with respect to settlement.
