    Abstract

    This specification covers the material requirements for preformed elastomeric strip seals and the corresponding steel locking edge rail used in expansion joint sealing. The scope of this specification is limited to preformed non-reinforced strip seals that mechanically lock into structural steel locking lugs. The sealing element can consist of a single layer strip or have multiple webs depending on individual project requirements. When used on highway bridges, limits on maximum joint opening and minimum steel thicknesses need to be addressed. The adhesive-lubricant used to install the preformed seal into the steel locking edge rail shall be a one part moisture curing polyurethane compound. The elastomeric seals shall conform to the physical properties prescribed for (1) tensile strength, (2) elongation at break, (3) hardness, (4) oven aging, (5) oil swell, (6) ozone resistance, (7) low temperature stiffening, and (8) compression set. Requirements for preformed elastomeric seal dimensions, sampling, and test methods to determine compliance with the specified physical properties are given.

    1. Scope

    1.1 This specification covers the material requirements for preformed elastomeric strip seals and the corresponding steel locking edge rail used in expansion joint sealing. The scope of this specification is limited to preformed non-reinforced strip seals that mechanically lock into structural steel locking lugs. The sealing element can consist of a single layer strip or have multiple webs depending on individual project requirements. The structural steel locking edge rail shall be anchored into the structure in accordance with the purchaser's specific details. While the scope of this specification is limited to the materials used in fabrication of strip sealing systems, it is recommended that a practical means of testing the watertightness aspects of the individual systems either in the field or at a testing laboratory be developed. When used on highway bridges, limits on maximum joint opening and minimum steel thicknesses need to be addressed.

    1.2 The values stated in the inch-pound system shall be considered as standard.
