摘要：	The purpose of this project was to improve the effectiveness of the drainage system at the referenced project location and to evaluate the Premier Pipe relining process as an alternative pipe rehabilitation method. The 'pipe-in-pipe' rehabilitation process requires little or no excavation, is designed to improve flow in deteriorated pipes, and can save time and cost of total reconstruction. The method used inner tubing of polyester felt, outer coating of polyurethane, and thermosetting resins. The process involved placement of an inverted pliable resin saturated tube positioned against the walls of the existing, deteriorated pipe, and heat treated to form a strong new 'pipe in a pipe.' The process was implemented on approximately 400 linear feet, 30 inch diameter, corrugated steel storm sewer pipe on station 16 + 24 Left of Ramp R to station 25 + 00 on Ramp Q in Lancaster along State Route 30. The pipe was filled with debris for almost the entire length. After the relining process, satisfactory performance was recorded during a four-year study. The manufacturer failed to provide proper documentation for product approval so that it could be listed in Publication 35, Bulletin 15.
