Abstract:

Due to lightweight and flexibility, orthotropic steel deck bridges became popular in the last decades but several problems were reported in relation to asphalt surfacing materials, such as, rutting, cracking, and loss of bond between the surfacing system and the steel deck. In the Netherlands, a surfacing structure for orthotropic steel bridge decks mostly consists of five structural layers: top porous asphalt layer, guss asphalt layer, steel deck and two membrane layers. The five-point bending fatigue test (5PBT) is the standard device in France for asphalt concrete used on steel orthotropic deck bridges to determine the best asphalt mixture having a strong resistance to cracking. For the needs of this paper the 5PBT was employed in order to evaluate the performance of the whole multilayer structure on steel decks and also to evaluate the mechanical properties of both top and bottom membrane and the influence they have on the structure. For the completion of the experimental investigation two types of specimens have been tested using the 5PBT set up. Displacement sensors have been used in order to detect the initiation of cracks where they are most likely to appear. Strain gauges have been used in order to monitor significant changes in strain on the guss asphalt layer during the fatigue tests. Shear displacements between the asphalt layers are monitored and presented. These show that the stiffness and the bonding characteristics of the intermediate membrane sheet, as well as the wearing course behaviour, seem to have great influence on the mechanical response of multilayer bridge surfacing systems.
