Measurement Program for Evaluation of Concrete Ties and Fastenings in Transit Track.

摘要

This report outlines a measurement program to obtain data on the performance of standard tie designs and associated fastening systems under field service conditions. In addition,the program identifies limited data to be obtained from a wood tie track for comparison. Recommendations are presented for a measurement program for monitoring,over an extended duration,the performance of different cross tie track systems under typical transit conditions. The following topics are discussed herein:type of data to be collected;type of instrumentation to be installed;type of equipment required for data acquisition;test schedule;and criteria for evaluating test data. The recommendations presented in this report are applicable to wood and concrete cross-tie track systems.
