SOME REFINEMENTS IN EXPANSION JOINT SYSTEMS

Testing and performance inadequacies of the widely used compression seals can be eliminated to a large degree by the use of mechanically locked seal elements. Rehabilitation techniques for expansion joints on older structures utilizing strip seals, low-stress sealing glands, and special low-profile elements are discussed. Major improvements in the rubber cushion concept are advanced, such as armoring for protection against snowplows and attrition, new curb and gutter techniques utilizing weldments for multidirectional changes, and lowering of detrimental force transmission. Improved modular systems for very large movements, methods of raising existing systems to meet asphalt overlay requirements, field splicing techniques utilized in lane-at-a-time reconstruction, and important noise reduction developments for urban environments are evidenced in case history evaluation.
