Correlation of Concrete Tie Track Performance in Revenue Service and at the Facility for Accelerated Servic Testing. Volume 1. A Detailed Summary

摘要

This report is the first of three volumes which describe a comparative study of concrete tie track in U.S. revenue service and at the Facility for Accelerated Service Testing (FAST). The work was undertaken to develop an understanding of the degree to which FAST represents the 'real world' of revenue service. The loading environment, structural characteristics and long-term performance of concrete tie track at FAST were compared with corresponding data from four concrete tie track segments in revenue service.
