An update in the technology of buried plastic pipe. 17 peer-reviewed papers in sections on Field Testing, Design and Installation, Rehabilitation, Laboratory testing, and Trenchless Construction.

Topics include: • effects of acid environment on PVC pipe • analysis of rehabilitation techniques • three-dimensional visoelastic finite-element model to predict circumferential stress and strain in HDPE pipes • design methodology for buried HDPE manholes that accounts for both the rind-directed and axially-directed effects of applied earth pressure • new test for studying behavior for buried plastic pipes in hoop compression.
