(Specification)Standard Specification for Joints for Concrete Pipe, Manholes, and Precast Box Sections Using Preformed Flexible Joint Sealants (Metric)
Standard Specification for Joints for Concrete Pipe, Manholes, and Precast Box Sections Using Preformed Flexible Joint Sealants (Metric)
ABSTRACT
This specification covers joints for precast concrete pipe and box and other sections using preformed flexible joint sealants for use in storm sewers and culverts which are not intended to operate under internal pressure, or are not subject to infiltration or exfiltration limits. Joint material used in horizontal applications is intended to prevent the flow of solids through the joint. The acceptability of the pipe joint and sealant shall be determined by the results of the physical tests prescribed. Bitumen sealants shall be produced from asphalts, hydrocarbon resins and plasticizing compounds reinforced with inert mineral filler and shall contain no solvents. Butyl rubber sealants shall be produced from blends of butyl rubber and refined hydrocarbon resins and plasticizing compounds reinforced with inert mineral filler and shall contain no solvents. The joint design shall consist of a bell or groove on one end of the section and a spigot or tongue on the adjacent end of the joining section. The different test methods for the determination of the composition and physical properties of bitumen or butyl sealants are presented in details. The sections shall be tested hydrostatically in vertical alignment and a sufficient number of sections shall be assembled in straight alignment.
SCOPE
1.1 This specification covers joints for precast concrete pipe and box and other sections using preformed flexible joint sealants for use in storm sewers and culverts which are not intended to operate under internal pressure, or are not subject to infiltration or exfiltration limits. Joint material used in horizontal applications is intended to prevent the flow of solids through the joint.
1.2 Precast concrete manhole sections and other vertical structures that are subject to internal or external pressure, infiltration, or exfiltration limits are not prohibited from being specified. Joints in vertical structures covered by this specification are intended mainly to prevent the flow of solids or fluids through the joint.
1.3 This specification is to be used with pipe and structures conforming in all respects to Specifications C14M, C76M, C478M, C506M, C507M, C655M, C985M, C1433M, C1504M, and C1577, provided that if there is a conflict in permissible variations in dimensions, the requirements of this specification shall govern.
1.4 This specification is the metric companion of Specification C990.Note 1—This specification covers the material and performance of the joint and sealant only. Infiltration and exfiltration quantities for installed sections are dependent on factors other than the joints which must be covered by other specifications and suitable testing of the installed pipeline.
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 and health practices and determine the applicability of regulatory limitations prior to use.
