The current standard of practice for the installation of agricultural mains is in accordance with ASTM F449, Standard Practice for Subsurface Installation of Corrugated Polyethylene Pipe for Agricultural Drainage or Water Table Control. ASTM F449 has several limitations. Currently, the allowable maximum height of fill is limited unless an engineering design is performed. In addition, the material requirements of F449 limits agricultural mains to corrugated high density polyethylene (HDPE) pipe meeting the requirements of ASTM F667 or F2648. The original overall objective of the research project is to perform an engineering analysis, including field verification, with supporting documentation to evaluate corrugated HDPE pipe of 12 to 60 in diameter in agricultural main installations using various shaped trench bottoms. This research will serve as a basis for engineering designs that can be referenced by manufacturers, specifiers, and owners. The project encompasses four phases including a literature review, finite element analysis of 30" and 48" pipe, and monitoring of an instrumented 36" field installation.

In PPXX, a technology was presented for the first time that could bi-axially orient polyolefin pipes. With this technology, it is possible to prepare pipes that have a performance far beyond the standard ones. One approach to achieving this performance is via a continuous in-line process. To optimize the in-line...

In March 1999, a project report on the performance of buried Thermoplastics pipes was published by TEPPFA /1/. In the report, deflection and strain data on buried pipes were analyzed and compared with calculation results from several well-known static calculation models in use in Europe. Pipes were installed to...

The required wall thickness for a fully fused HDPE water main subject to an earthquake induced lateral spread is addressed in this paper. The water main is assumed to be buried via cut and cover (i.e., open cut with typical burial depths in the 2 to 15 feet range) procedures and any laterals have small diameters. For...

The Notched Constant Ligament Stress test (NCLS test, ASTM F2136)[1] is a test method that measures the slow crack growth in High Density Polyethylene. The NCLS test requires a notch on all test specimens to act as a stress concentration at that point so crack propagation can be easily predicted and studied. In...
