Assessment of the structural pavement condition plays a crucial role in an economic pavement maintenance planning. An existing database for the monitoring and evaluation of pavement condition provides a good basis, but it is limited to the evaluation of surface properties. Bearing capacity measurements are therefore an important component when it comes to the assessment of structural pavement condition; however, they are rather used punctually in the context of established measurement methods due to measuring velocity and the possibly related obstruction of traffic flows.
