Installation of steel, plastic and concrete pipe under highways is a complex challenge for transportation agencies. Knowledgeable field staff and appropriate specifications are critical to ensuring properly functioning, long life culverts that also provide for a smooth ride to the traveling public. This presentation will include an overview of pipe types and selection criteria and it will also cover field installation best practices.

Presentation will include:

  • Concepts of the three primary types of pipes/culverts and storm sewer conduits: steel, plastic and concrete
  • Conduit material and manufacturing basics
  • Conduit capacities – flow basics
  • Proper installation techniques – pipe/soil envelope
  • Acceptable construction storing and handling methods
  • Excavation and bedding material
  • Compaction concepts
  • Installation best practices
  • Conduit joints and end treatments
  • Post installation acceptance
