908.14 Smooth Bituminous Lined Corrugated Steel Sewer Pipe. The pipe and the coupling bands shall be galvanized steel or aluminum coated steel in accordance with AASHTO M 36. The pipe shall be fabricated with circumferential corrugations and riveted lap joint construction or with helical corrugations with continuous lock or welded seam extending from end to end of each length of pipe. Band couplers, fittings and connections, and sheet metal shall be in accordance with 908.02. After fabrication, the pipe shall be fully bituminous coated in accordance with 908.07. The inside of the pipe shall be coated with bituminous material, in accordance with the same requirements for the initial coating, so that a smooth surface is formed which completely fills the corrugations. The minimum thickness above the crests of the corrugations shall be 3 mm (1/8 in.). Straight pipe shall have the interior coating applied by means of a centrifugal method or other approved method. The bituminous coating of the interior lining of the finished pipe shall be of uniform thickness and shall be free of cracks, sags, or runs. The pipe shall be so fabricated and field jointed such that the inside periphery of the pipe shall be smooth and even across each joint. Space between adjoining sections shall be filled with the same material used for the coating. The bituminous liner material furnished under this specification shall be covered by a type B certification in accordance with 916 for each 300 m (1000 linear ft) of pipe coated. The type B certification will be required once per week if less than 300 m (1,000 linear ft) of pipe is coated in the week. One sample of bituminous material will be obtained per week from the working tank for verifications testing. SECTION 916, AFTER LINE 59, INSERT AS FOLLOWS:
