haul road modelisation
Dear Maxime,
The choice of modelling a material depends on the behaviour and properties of the material. MOT Type 1 is geotechnically not a single material as it can consist of limestone, granite and even crushed concrete. Hence, you would have to have an idea how this material behaves under loading to see if modelling it using Mohr-Coulomb would be sufficient or that you would better move into modelling it with Hardening Soil.
With kind regards,
Dennis Waterman
