Multi-disciplinary geophysical investigation to identify road failure mechanism

Abstract

Summary Case study investigation failure mechanism of a road in Derbyshire (UK). The road is located on a ridge, with steep slopes on either side as well as known historical mineworkings in close vicinity. A multi-disciplinary geophysical survey was executed to identify the potential failure mechanism after cracks in the road surface were observed. The combined interpretation of all techniques provided a detailed image of the subsurface allowing identification of the most likely failure mechanism, which will be used in design of a remediation strategy.
