Interaction between the road construction and the subsoil (A07)

• Subject Area: Geotechnics, Hydraulic Engineering
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 453596084

TP A07 is focused on the investigation of a state- and direction-dependent stiffness of the subsoil and accumulation processes of irreversible deformations resulting from the traffic load and the climatic changes. A suitable constitutive model with corresponding state variables of the subsoil will be defined and linked with the structural model of the road (TP A01, B04). In case of progressive deformation or softening of the subsoil, warning states can be activated and countermeasures can be initiated.
