- Abstract:
- Comparative studies were conducted on four different protocols in this work, including the fourth edition of Sewer Rehabilitation Manual (SRM-4) in Britain, Pipeline Assessment and Certification Program (PACP) in America, Sewer Physical Condition Classification Manual (SPCCM) in Canada and Technical Specification for Inspection and Evaluation of Urban Sewer (CJJ 181-2012) in China, which aim to find out their differences in defects definitions, the characteristics of defect code compilation and the assessment processes. Major reasons for the different assessment results from each protocol have been revealed. The results show that the main reasons for the differences on the defect definitions are different application areas, different pipeline repair technologies, new progress in pipeline defect research and different definitions of structural defects and functional defects. The main reason for the difference of assessment results is the difference of defect scores and assessment parameters.
