538.01 Description.
This Section shall cover the work of rehabilitating roadway pipe using a cured -in-place liner, polyethylene (PE) liner pipe, or a liner shown on the plans, at the locations shown on the plans or directed by the Engineer.
538.02 Materials.
a.Cured -in-Place Liner. Cured -in-Place Liner material shall be a lining system selected from List II -32 of the Department’s MSDSAR . All cured -in-place lining products shall comply with ASTM F -1216, "Rehabilitation of Existing Pipelines and Conduits by the Inversion and Curing of a R esin-Impregnated Tube", ASTM F -1743, "Rehabilitation of Existing Pipelines and conduits by Pulled -in-Place Installation of Cured -in-Place Thermosetting Resin Pipe (CIPP)", or ASTM F -2019 “Rehabilitation of Existing Pipelines and Conduits by the Pulled in P lace Installation of Glass Reinforced Plastic (GRP) Cured -in-Place Thermosetting Resin Pipe (CIPP), including appendices. The liner shall be a flexible tube fabricated to a size that, when installed, shall fit the internal circumference of the existing ro adway pipe. Allowance shall be made for circumferential stretching during insertion so that the final cured product is snug against the wall of the host pipe. The material shall be able to stretch to fit irregular pipe sections and negotiate bends. Any com pounds, process water or condensate used during the installation or curing operation shall be contained, removed from the site and disposed of in a manner approved by the Engineer.
b.PE or HDPE Liner Pipe. Polyethylene or high density polyethylene liner pipe shall be selected from List II -32 of the Department’s MSDSAR .
c.Liner Shown on the Plans. Any liner shown on the plans may be used as an alternate to cured -in-place liner or PE liner pipe. The material requirements for alternate liners will be show n on the plans.
d.Minimum Length of Liner. The minimum length of liner material shall span the distance from the inlet to the outlet of the pipe, unless required otherwise by the Engineer or shown otherwise on the plans.
538.03 Construction Requirements .
a.Submittals. The Contractor shall submit eight copies of the product data and installation procedures of the cured -in-place liner, or PE liner pipe for review and distribution.
