The Test Report can be found here: Service Life Assessment of Internal Replacement Pipe: External Load Testing of I-MainTM 

This document reports on a testing program performed on 12-in.- (300-mm) diameter specimens repaired with ALTRA10TM internal replacement pipe (IRP). Five specimens were tested, including those with steel (4) and CI (1) host pipes.

The intent of this study is to impose external loading conditions to test specimens that are representative of the significant deformations possible during earthquake-induced ground motions such as landsliding, fault rupture, and liquefaction-induced lateral spreading, characterizing the pipeline system capacity.

Report by H.L. Parnell, L. Guerrero, B.A. Lucero, and B.P. Wham.

The first in a series of testing programs at CU Boulder CIEST investigating performance of critical lifeline systems under extreme loading conditions.
