Ice Road Assessment, Modeling and Management
The Tibbitt to Contwoyto Ice Road, situated north of Yellowknife in Canada’s Northwest Territories is the world’s longest heavy haul ice road. This ice road carries more than 8,000 truck loads annually of various axle configurations during a haul season restricted to mid-January through mid-April. Similar to its unfrozen counterpart, the load bearing capacity and performance of this road is influenced by the frozen surface structure and composition and the water depth and structure beneath the ice sheet. Although the frozen roadway disappears each spring, the effective management of this infrastructure asset is critical to the exploration and mining operations along its route. This paper presents background information on ice sheet dynamics and the recent development of innovative non-destructive ice sheet measurement and distress assessment technologies. It is believed that these technologies will allow comprehensive ice sheet characterization and performance modeling not previously possible. It is anticipated that these innovations will significantly extend ice road engineering and management capabilities.
