9 June 2000 Long-term monitoring of highway deformations
Author Affiliations +
We report on the development of a measuring system for dynamic long-term monitoring of highway pavement; i.e. the relative vertical displacements within the pavement layers. Beside the knowledge of weight and frequency of vehicles it is more and more of interest to know the vertical deformations within the pavement layers due to the traffic loads. Our displacement measurement is based on the magnetostrictive principle. Several positions along one measuring axis corresponding to the different layers of the pavement are monitored. The development of the measuring system, the calibration, the embeddment in a test pavement and first test results will be presented.
