This case history describes the construction of a steep embankment, reinforced with geogrids, on Highway 410 near Brampton, Ontario, Canada. The embankment was 7m high with 45 degree slopes. The decision to build it there was based on economic considerations and property constraints. Reinforcing geogrids were included, to improve the internal and surface stability of the slopes. They were designed to provide additional resisting forces to an otherwise unstable geometry. The following tensile elements were incorporated: (1) a Tensar SR2 geogrid in the fill, to provide overall external stability; (2) a Tensar SS1 geogrid, to provide internal strength in the granular frost protection zone; (3) a Netlon CE111 geonet on the embankment surface, to protect against surface erosion. After the embankment's completion, deformities within the fill material were monitored by multipoint magnetic extensometers, and stresses in the reinforcing geogrids were measured by strain gauges.
