The SDDOT completed a research project SD96-11 Evaluation of High Density Polyethylene (HDPE) Pipe in 1998. This project did not evaluate embankment sites. Some contractors do not have the necessary equipment to install pipe in a trench site. Contractors often install pipe in an embankment installation; therefore, research is needed to evaluate the installation of HDPE pipe in both an embankment installation and a trench installation. This evaluation is designed in part to ensure that the needs of both the contractor and the SDDOT are satisfied. Recommendations from SD96-11 indicated a need to install and evaluate HDPE pipe in various soil types. The SDDOT needs to have an efficient way to evaluate the performance of HDPE pipe.
