We are pleased to share our latest findings in a research study conducted in partnership with the Department of Civil and Environmental Engineering at the University of Alberta. The experiment program was conducted and documented by students Linping Wu and Wei Victor Liu from the University of Alberta and Riley Cram and Diana Nicholson of Cypher Environment. The overall objective of the proposed research was to develop a new design approach for mine haul road pavements with stabilized layers.
The research first set out to develop and validate 2D and 3D Finite Element Models (FEM) that were later used to investigate the effects of stabilization on the strain and deflection of a mine haul road and rural municipal road. The study found that not only does stabilization reduce the strain and deflection of roads, it also found that the stabilization of lower layers was more effective in reducing the strain and deflection as compared to the surface layers. These findings led to a new design approach that took into account the theories of elasticity and critical strain limit (CSL) to improve stabilization of the road (CBR). Improved stabilization directly correlates to enhanced performance through improvement in vehicle speed, reduction in wear and tear on vehicles, reduced downtime caused by accidents and injuries from unsafe road conditions.
