2014 - Austria - Improving PMS Predictions with Laboratory Tests

The integration of material-science based performance models obtained from laboratory performance testing and modelling into life-cycle-assessment of road pavements is a future oriented approach for the improvement of  performance prediction. This shall significantly improve the selection processes for maintenance strategies within pavement management as well as during the design of new pavements. Maintenance options can be selected based on material behaviour and improved prognosis of long-term performance of the pavement structure. Within the ERA-NET ROAD II project InteMat4PMS – ‘Integration of Material-science based performance models into life-cycle-analysis processed in the frame of Pavement Management Systems’ – this
approach was developed and tested in practice on two test sections in Germany. The output of this project is presented in this paper.
