Specifications include, but are not limited to: A. Tube Liner: Tube liner will consist of at least two separate tubes made of corrosion resistant (E-CR or equivalent) glass fibers according to ASTM D578 and ASTM F2019. Provide flexible liner tubing that exhibits the following characteristics.; • Constructed to withstand pulling and installation forces.; • Fabricated to a size that when installed, conforms to the internal circumference and length the of host pipe.; • Includes an impermeable inner and outer foil layer to contain resin migration and contamination.; B. Resin: Resins will meet the requirements of ASTM F2019, Section 5 for UVlight cured.; C. Slide Foil: A continuous heavy gauge plastic sheet for the purpose of covering the lower portion of the host pipe, protecting the liner during the pull in process.; Minimum Design Service Life Greater than 50 years; Pipe Condition Gravity Pipe - Fully Deteriorated*; Soil Load 120 lbs./Cu.Ft.; Live Load AASHTO LRFD Article 3.6.1.2.6; Pipe Ovality1 Minimum 2% for RCP host pipe; Minimum 3% for CMP host pipe; Minimum Factor of Safety 2.0; Inside Pipe Diameter Refer to plan sheets; Pavement type Refer to plan sheets**; Height of fill from invert to top of road Refer to plan sheets Height of Water above Top of Pipe Top of pipe unless site conditions indicate higher; Field verify pipe inside diameter(s) throughout the pipe, length(s), alignment, material and condition of the host pipe prior to ordering liner material and construction. Handle and store all liner material to ensure that the material is not torn, cut, exposed to direct sunlight or otherwise damaged.; The host pipe will be thoroughly cleaned using a high-pressure water jet or hydromechanical methods. The cleaning method will produce a clean, sound surface that demonstrates no evidence of loose material, debris or contaminates. The host pipe will be cleaned just prior to insertion of the CIPP liner. The Contractor will implement appropriate sediment control measures prior to cleaning in order to prevent discharges from the project boundaries to comply with the Storm Water Permit.; Material removed from the pipe culverts will become the property of the Contractor for disposal.; Host pipe inspection will be completed with a CCTV camera. A DVD recording (or other Engineer approved method) of the inspection will be provided to the Engineer. The inspection will determine the suitability of the liner for the host pipe including such items as the horizontal and vertical alignments, location of gaps in the joints and pipe damage. The Engineer will be notified if any pipe sections are impassible, or the pipe cannot be lined.; Any intrusions into the pipe will be cut or ground off flush with the host pipe interior wall before installing the liner. Cut off existing pipe tie bolts flush with the nut or as per the manufacturer’s recommendation, if manufacturer’s recommendations are more stringent.; Control groundwater infiltration that will interfere with installation of the CIPP liner. Dewatering may be necessary. Host pipe will be in a dry condition as prescribed by the CIPP liner manufacturer.
