【国外标准】 Standard Specification for Joint and Crack Sealants, Hot Applied, for Concrete and Asphalt Pavements

This specification covers four types of 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. However, this specification does not address the properties required of sealants for use in areas of Portland cement concrete or asphaltic pavement that are subject to jet fuel or other fuel spillage such as vehicle and/or aircraft refuel and maintenance areas. The sealants shall be sampled and tested appropriately to examine their conformance with specified values of the following requirements: cone penetration; softening point; non-immersed and water-immersed bond properties; oven aged resilience; and asphalt compability.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 This specification 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.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
