Abstract:This project summarizes an evaluation of pipe material resistance to abrasion over a 5-year period (2001-2006) at a site known to be abrasive.
The key focus of the project was to gather more information to compare against existing guidance to designers on evaluation of pipe material resistance to abrasion. To date, studies performed by others in laboratory settings have been limited and have not sufficiently reproduced real-world conditions for the entire range of pipe, and pipe lining products available today. See Appendix D.
The objective of this research project was to evaluate various pipe and pipe liner products for their relative resistance to abrasion at a real-world abrasive test site. Results obtained from measurement and field observation will provide a major portion of the basis to update current design guidance and abrasion related input for Caltrans alternative pipe material service life predictions.
