In this study, the field construction with the prefabricated lightweight plastic foundation using recycled plastic forsewage pipeline and triple wall PE sewer pipe was carried out to verify the construction workability of prefabricated plasticfoundation and deformation resistance potential of triple wall PE sewer pipe. The construction procedure in field wasfollowed the KS standard. The measured vertical deformations of PE pipe are average 2.35mm which means around 1%of deformation for 300mm diameter of PE pipe. Judging from the type of foundation, the use of plastic foundation (CaseB & Case C) showed lower deformation due to differential settlement than that of sand bedding foundation. Especially,the plastic foundation made a relatively uniform deformation of PE pipe. However, the sand foundation represented thenon-uniform deformation of PE pipe.
