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.
