(Specification)Standard Specification for Lubricant for Installation of Preformed Compression Seals in Concrete Pavements
Standard Specification for Lubricant for Installation of Preformed Compression Seals in Concrete Pavements
ABSTRACT
This specification covers a lubricant suitable for facilitating the insertion and positioning of preformed elastomeric compression seals in prepared voids (usually contraction joints) in concrete pavements. The lubricant shall be based on polychloroprene, containing only soluble phenolic resins blended together with antioxidants and acid acceptors in a suitable mixture of organic solvents. The requirements of the lubricant are based on the performance of the lubricant as measured by its solids content, homogeneity, consistency and drying rate.
SCOPE
1.1 This specification covers a lubricant suitable for facilitating the insertion and positioning of preformed elastomeric compression seals in prepared voids (usually contraction joints) in concrete pavement.
1.2 The requirements of the lubricant are based on the performance of the lubricant as measured by its solids content, homogeneity, consistency and drying rate.
1.3 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of U.S. customary units may be approximate.
1.4 The following precautionary caveat pertains only to the test method portion, Section 7 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
