Currently, the design method of haul road pavements cannot address the rolling resistance under the effects of stabilizers in pavement design. To address this, the overall objective of this research is to develop a new design approach using finite element modeling for mine haul road pavements with stabilized layers. In particular, the prediction of rolling […]

Throughout much of northern and rural Canada roads are constructed of unpaved gravel aggregate. They are expensive to maintain, environmentally problematic and degrade quickly. We are developing a solution to this problem by using locally derived materials rich in reactive clays. With the addition of catalysts and polymeric agents, we cause the fine clay materials […]

Unpaved gravel roads throughout rural and northern Manitoba and across Canada are made from poorly bound aggregate materials. Consequently they quickly deteriorate to loose, rough and dangerous road conditions. They generate choking and noxious dust clouds when dry, and quickly lose strength and degrade to mucky and rutted conditions when wet. The goal of this […]
