c.Polyvinyl Chloride. TEST TEST METHOD REQUIREMENT Polyvinyl Chloride Waterstops Corps of Engineers CRD -C572 Compliance of paragraph 6 707 JOINT MATERIAL
707.03.04 Joint Sealer for Weakened Plane Joints in Portland Cement Concrete Pavements. Use joint
sealants listed in the QPL. Place all sealants according to the manufacturer’s recommendations. Furnish 2 copies of the manufacturer’s recommendations not less than 14 days in advance of beginning joint sealing operations.
707.03.05 Preformed Elastomeric Joint Seals. Preformed elastomeric joint seals shall conform to ASTM
D3542. The seals shall consist of a multiple- web design, function only by compression between the faces of the joint, allow for movement of the bridge, and seal the joint against admission of moisture. The minimum nominal depth of the seal shall be at least 95% of the uncompressed width. The movement rating of each seal, as determined by ASTM D3542, shall be not less than the movement rating as shown on the plans. SECTION 708 CONCRETE AND PLASTIC PIPE SCOPE
