(Specification)Standard Specification for Joint and Crack Sealants, Hot Applied, for Concrete and Asphalt Pavements
Standard Specification for Joint and Crack Sealants, Hot Applied, for Concrete and Asphalt Pavements
SCOPE
1.1 This specification covers joint and crack sealants of the hot applied type intended for use in sealing joints and cracks in Portland Cement Concrete and Asphaltic Concrete Pavements.
1.2 The values stated in SI units are the standard.
1.3 This standard does not purport to cover the properties required of sealants for use in areas of Portland Cement concrete or asphaltic pavement subject to jet fuel or other fuel spillage such as vehicle and/or aircraft refuel and maintenance areas.
1.4 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 requirements prior to use.
