CONSTRUCTING A GEOGRID-REINFORCED RAIL EMBANKMENT

This article is a case study of a geosynthetic-reinforced soil embankment that was installed to replace a 63-year-old steel girder rail bridge. The project site, located near St. Leonard, New Brunswick, Canada, is part of the Canadian National Railways system. The bridge was part of the main line, carrying traffic from the Maritimes to the rest of Canada. Annual maintenance for the bridge was high due to persistent lateral movements, so the railroad's solution was to replace it with a 12.2-m-high earthen embankment. This case study reviews the design and construction details of the project, including special considerations for the site's heavy cyclical loading requirements, saturated foundation soils, steep side slopes, and the adjacent waterways' influence. Rapid construction techniques required to limit interruption of rail service and strict environmental protection regulations that had to be met are discussed also.
