PREFORMED ELASTOMERIC JOINT SEALERS FOR BRIDGES

A proven effective solution to the problem of sealing joints in bridge decks is described. The basis of the solution is the use of specially designed joint armor in combination with currently available, preformed elastomeric sealers. The approach is adequate for simple-span, composite, concrete, or steel structures having span lengths up to 52 m (170 ft). The special armored-joint system was field tested on three structures. Two of these were monitored both manually and with automatic instrumentation to determine the causes and range of magnitudes of bridge-end movements; they were also tested for leakage with dyes at periodic intervals over a 5-year time span. The third structure was used to conduct load tess on the joint armor and armor anchorage components. Application of the results led to the development of practical procedures for the design and construction of armored bridge joints and the selection of an appropriate size of elastomeric sealer. /Author/
