Innovative Geotechnical Repair Techniques: Comparative Life Cycle Assessment

This report estimates the carbon impacts of four methods used in stabilizing a twenty-five degree highway slope. The four techniques are: Granular Rock Fill Replacement (used as a control); Willow Pole planting; Fibre Reinforced Soil (FRS); and Electrokinetic Geosynthetics (EKG). These were compared using a life cycle assessment. Five life cycle steps were examined, from the acquisition of materials to the construction of the stabilized slope. The greatest environmental impact was from the Granular Rock Fill Replacement control. The Willow Poles technique had the least impact. Techniques requiring large quantities of materials and movements of materials across distances, accounted for more than half of the total carbon impact.
