239(n) Pipe to Structure Connections and Waterstops: Manufactured pipe connection systems for connecting pipe to drainage structures shall be submitted to the Materials Division certifying the system meets the requirements for Soil-Tight, Silt-Tight, or Leak-Resistant in order to be on the approved list. When resilient connectors for silt tight connections are specified for concrete pipe to concrete structures, the connectors shall meet the requirements of ASTM C1478. When resilient connectors for leak resistant connections are specified for flexible pipe to concrete structures, the connectors shall meet the requirements of ASTM F2510. When waterstops are specified, they shall meet the requirements of ASTM F2510, Section 4.1 Mate - rials and Manufacture and Section 4.2 Mechanical Devices. The waterstop shall have a 1 inch min - imum keylok anchor embedded into the concrete or mortar connection on pipe sizes below 18 inch diameter and 1.5 inch for pipe 18 inches and greater in diameter. There shall be a minimum 2 inches of concrete or mortar connection around the rubber gasket to permit proper consolidation around the gasket. All waterstops shall be secured to the pipe with a take-up clamp before applying mortar. SECTION 233—GAL V ANIZING
233.01 Description
These specifications cover the use and repair of zinc coatings (galvanizing) on a variety of materials.
233.02 Detail Requirements
Galvanizing of fabricated items shall be performed after fabrication. Galvanized items shall be stored off the ground in a manner that will allow free drainage of water from galvanized surfaces.
a.Galvanizing of iron and steel hardware shall conform to ASTM A153 for the hot-dip process or ASTM B695, Class 50, for the mechanical process.
b.Galvanizing of rolled, pressed, and forged steel shapes, plates, bars, and strips shall conform to ASTM A123.
233.03 Repair of Galvanized Surfaces
Galvanizing surfaces that have been damaged or have uncoated areas shall be repaired in accordance with ASTM A780 except that repair materials shall not contain lead or cadmium. SECTION 234—GLASS BEADS FOR REFLECTORIZING TRAFFIC MARKINGS
234.01 Description
