Service life prediction. The design life of conventional drainage pipe is normally 50 years but it can span up to 100 years, which is the design life we assume (Leshchinsky and Chajes, 2003; Pluimer, 2006; Wang et al., 2012a,b).For this reason, Nguyen (2017) performed experiments validated against literature to predict the service life of recycle blended alternative pipe materials as [price]Resources Uni Bell PVC Pipe Association[hdpe]HISTORY VALIDATES AWWARFS 1994 FINDINGS ON PVC PIPE PERFORMANCEA LOOK BACK TWENTY FIVE YEARS LATER.
