EXPANSION JOINTS FOR USE IN HIGHWAY BRIDGE DECKS

This Standard supersedes Technical Memorandum SB 2/74 and describes the loads and movements to be used for the design of bridge expansion joints, giving the requirements for their selection and installation. Detailed advice, accompanied by sketches, is given in an Appendix on the installation of a number of commonly used joints including, buried asphalt plug, nosing, elastomeric and cantilever types. Guidance given is based on information from site inspections, surveys and feedback from various sources. Key factors affecting joint performance are tabulated. Selection of the appropriate type is determined by the total design range of movement expected for the serviceability limit state. Specific advice is not given on joints to accommodate movement greater than that provided for by proprietary joint systems, but the basic principles discussed still apply. An effective drainage system should be provided immediately beneath the expansion joint with access for inspection and maintenance. Examples are given of typical watertight drainage seals which will assist also in the exclusion of grit and dirt. Advice is given on the preparation of the deck and the setting and sealing of gaps.
