Transition zones between bridges and embankments are the most maintenance-prone locations in the Netherlands road network due to the very compressible soft soils present in the largest part of this country, resulting in severe differential settlements and cost impact. This study shows how to exploit both conventional and DInSAR monitoring datasets in order to forecast future settlements and assist the Road Manager in the decision making process of new maintenance operations.

In the Netherlands, subsidence of peat and clay soils due to (artificial) lowering of the groundwater table and loading of soft soils causes extensive damage. The topic is a major concern to homeowners and public authorities but an integrated risk assessment is currently lacking. In this paper, we propose a modular methodology for the systematic countrywide assessment of two subsidence-related damage mechanisms to buildings. Its application will support private and public decision-making.
