Failure mode and effect analysis of concrete ties in North America

Research output: Contribution to conferencePaper

Abstract

A failure mode and effect analysis ( FMEA) was applied to improve the design of concrete ties in ballasted track for North American heavy haul applications. A literature review was conducted on concrete tie failure modes, failure effects, and failure causes. A survey of railroads and transit authorities in North America provided a ranking of the most critical concrete tie failure modes. The most important problem for heavy haul service was found to be rail seat deterioration ( RSD). The contributing factors, related failure modes, and deterioration mechanisms of RSD are discussed.
