Manholes, Using Rubber Gaskets
AASHTO Designation: M 315-07
ASTM Designation: C 443-05a
1.l This specification covers flexible watertight joints for concrete pipe and precast manhole sections, using rubber gaskets for sealing the joints, where infiltration or exfiltration is a factor in the design.
The specification covers the design of joints and the requirements for rubber gaskets to be used therewith, for pipe conforming in all other respects to Speci•
fication C 14, Specification C 76, or Specification C 507 and precast manhole section conforming in all other respects to Specification C 478, provided that if
there is conflict in permissible variations in dimensions the requirements of this specification for joints shall govern.
1.2 A complete metric companion to Specification C 443 has been developed-C 443M; therefore, no metric equivalents are presented in this specification.
