Haul Road Structural Design covers the selection of materials, defining a mechanistic structural model and design loads
Structural Design
Haul road structural design concerns the ability of the road to carry the imposed loads without the need for excessive maintenance or rehabilitation. Haul roads deteriorate with time due to the interactive effect of traffic load and specific sub-grade (in-situ) material strengths and structural thicknesses.
The California Bearing Ratio (CBR) structural design method has been widely applied to the design of mine haul roads in which untreated materials are used. However, when multi-layered roads are considered in conjunction with a base layer of selected blasted waste rock, a mechanistic approach is more often appropriate.
