Title of Contract, Award, or Gift: Spray Applied Pipe Liner Structural Design Methodology in Gravity Storm Water Conduits

Name of Granting or Contracting Agency/Entity: Ohio Department of Transportation (ODOT)

Program Title: N/A
CFDA Linked: Highway Planning and Construction


The primary objective of this research is to develop a design methodology for both cementitious and resin based spray applied pipe liner materials for structural rehabilitation of gravity storm water conveyance culverts. This design methodology will be applicable for round, elliptical, pipe arch, arch, and box shapes. All parameters of the host culvert that may impact the design thickness such as vertical or horizontal deflections, unsymmetrical racking, section loss, cracks, material geometry (corrugations), or protrusions such as bolts and flanges will be considered. Additionally, practical limitations on the use of this design methodology will be covered. Secondary objectives of this research include: Recommend a laboratory test method to verify the proposed structural design for culverts that have been rehabilitated using the spray applied pipe liner technology using various thicknesses. Recommend an accelerated laboratory methodology to determine the spray applied liner material durability. Recommend laboratory material testing standards for both cementitious and resin based materials.
