Abstract: Means are provided for reducing or eliminating leakage of water around rubber cushion expansion joints in highway and bridge pavements. Molded rubber cushion joint sections which are typically 4 to 6 feet long are spaced from each other, end-to-end and a flexible membrane is fitted between the facing ends to absorb shearing stresses between adjoining sections and seal the end-to-end connections. In addition, a hollow rubber tube is compressed between the sections and the pavement to seal against leakage around the joint sections.
