[en] In the time of increasing maintenance costs, the continuous inspection and the earliest possible damage
detection become more and more important. In order to minimize future maintenance costs, the exact evaluation of
the condition of the structure and the exact assessment of potential damages are of essential importance.
Therefore the University of Luxembourg carries out projects to investigate an efficient application of different
assessment methods taking into account praxis relevant test conditions. As a part of this project especially the
changing temperatures which influence the stiffness of the materials are analysed. As a consequence, for the condition
assessment of structures, the asphalt layer cannot only be taken into consideration as a mass applied as load on the
structure. Due to bond effects of the asphalt layer to the load carrying element its changing stiffness induced by
changing temperatures influences the stiffness of the whole structure.
Within this paper this effect will be illustrated. First the load carrying behaviour and the stiffness of pre-stressed
concrete slabs realized with and without an additional asphalt layer will be investigated in a climate chamber and the
results will be compared for different temperatures.
