**2.2 Geogrid reinforced embankment with steep side slopes**

For a highway project in Brampton, Ontario, property acquisition costs and other problems necessitated the design of 7 m high embankment with 1H:1 V steep side slopes. Cost–benefit studies showed that steep side slopes reinforced with synthetic tensile elements were considerably cheaper than the other alternatives. Design and construction of 7 m high embankment with slopes using geogrids (**Figure 4**) as an alternative to rock fill embankment with side slopes of 1.25H:1 V requiring additional land has been covered by Devata [6]. Reinforced earth slope was found to be most economical (**Table 1**). The total cost of 1H:1 V reinforced slope is the least among all the alternatives making it the most economical option.
