APT device evaluation for road research in Switzerland: test campaign on a Swiss Highway with the MLS10
2008 (English)In: Proceedings of 3rd Int. Conf. on Accelerated Pavement Testing, 2008Conference paper (Refereed)
APT facilities and testing devices have a long tradition in road research in Switzerland. Since the beginning of the seventies the Swiss Codes for road design have been strongly affected by the results of 7 test campaigns carried out on more than 35 pavement structures tested with the “Rundlauf” circular test track. The APT device MLS10, developed by the University of Stellenbosch in collaboration with Empa and the Institute for Geotechnical Engineering of the ETH Zürich has now being evaluated for replacing the “Rundlauf” circular test track. Some of the main advantages of the MLS10 are that it allows for a real road structure to be tested in situ, and in a much shorter time scale than with the “Rundlauf”.The machine capabilities have been long and accurately tested on a real Swiss Highway section. The mechanical properties of the road structure have been monitored and analyzed with a newly developed static deflection measurement device “ETH DELTA”. The test track surface conditions, the layer thickness, composition, and in situ conditions as well as the temperatures in different depths have also been collected. The results show that the MLS10 is able to reproduce the real loading conditions on an existing road structure, and it allows for the residual service life of a real road construction to be estimated.
