The theoretical concept, development stage, and comprehensive field testing in the full-scale use of preformed compression joint seals is discussed and documented.
A history of its early usage, which led to the selection of the necessary properties for quality control of elastomeric vulcanizates, typical configurations, machine installation techniques, use of lubricant adhesives as a companion material, plus the entry of compression seals in both airfield and highway pavements as well as architectural industrial environments, is described.
Some recent research is reported on, and the importance of relating specifications to environmental needs is emphasized.
Future trends, such as mechanical locking of seal elements to joint interfaces, uses of low profile seal elements, development of strip and gland type systems and their current application in bridges and structures, are discussed.
