Abstract:

The durability of geotextiles installed in railway rehabilitation applications is investigated by examining the track conditions and the change in properties of exhumed geotextiles at different time intervals. Properties examined include soil fouling content, change in permeability ratio, and change in geotextile strength. These properties are related, as appropriate, to characteristics such as filtration opening size. The results are discussed in terms of the geotextile's primary functions of filtration, drainage, separation, abrasion resistance, and elongation. Data collected before 1982 were used to develop a track rehabilitation geotextile specification for use without a capping sand. Data collected after 1982 were used to support and confirm the validity of the specification. This specification was adopted and has been in use in the Canadian National Railways Maritime Region since 1981. It has also been used for rehabilitation of other railway company tracks. Correctly installed geotextiles meeting the specification have given satisfactory performance and have been cost-effective.
