This specification covers joint and crack sealants of the hot applied, jet fuel resistant type intended for use in sealing joints and cracks in Portland cement concrete in areas that are subject to fuel spillage. Three types of joint sealants are presented: type I - joint sealant which is resilient and capable of maintaining an effective seal in hot to moderate climates, type II - joint sealant capable of maintaining an effective seal in hot to moderate climates, and type III - joint sealant capable of maintaining an effective seal in most climates experiencing moderate to cold temperatures. The specimen conditioning, cone penetration, aged cone penetration retention, and softening point shall be tested to meet the requirements prescribed. Non-immersed bond, water immersed bond, fuel immersed bond, resilience, and oven aged resilience shall be tested to meet the requirements prescribed. The tensile adhesion, artificial weathering, and flexibility of the sealant shall be tested to meet the requirements prescribed.
