isolated communities as well as the exploration and development of natural resources for economic growth in_x000D_
Canada. Accurately determining the safe bearing capacity for these ice covers is critical, and is closely_x000D_
dependent on the ice thickness as a design parameter. Technological advances such as Ground Penetrating_x000D_
Radar (GPR) now allow us to take thousands of ice thickness measurements in a fraction of the time that_x000D_
previous methods of drilling through the ice and manually measuring took. Despite GPR now providing a_x000D_
comprehensive understanding of the ice cover thickness profile, standard of practice dictates that the absolute_x000D_
minimum ice thickness measured must be the value used in design. Using the minimum ice thickness_x000D_
measured for calculating the safe bearing capacity of an ice cover does not consider the respective location,_x000D_
size, or frequency of the thin ice areas. This results in an overly conservative ice cover design, which has_x000D_
detrimental effects on communities and industries in the North. NOR-EX Ice Engineering Inc. requires an_x000D_
understanding of how variations in ice thickness impact the overall performance/bearing capacity of an ice_x000D_
road. The results of this research project will allow NOR-EX Ice Engineering Inc. to develop a methodology_x000D_
for using an effective ice thickness from GPR data rather than an overly conservative minimum ice thickness., program purpose french : Ice roads, ice runways, and ice platforms provide vital access to remote areas of Canada for the resupply of_x000D_
