The application of non-invasive geophysical methods for road transport sector can be divided into two categories. Geophysical methods are used during: design works – for clarification of geotechnical investigations and for the road surface and substructure monitoring. Depending on the terrain and geological conditions different geophysical methods are applied. Geophysical continuous surveys allow to determine local variations of ground parameters which is essential during designing and constructing roads in post-mining area where voids and local ground subsidences due to mining works occure.
