Abstract

Orthotropic steel deck bridges become popular the last decades due to light-weight and flexibility but then again 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 (5PB) beam test is the standard device in France for characterization of fatigue response of asphalt concrete used on steel orthotropic deck bridges. In this investigation, the 5PB test was employed in order to evaluate the fatigue life of the asphalt multilayer structure on steel deck and also to evaluate the mechanical properties of both top and bottom membrane and the influence they have on the structure. Four membrane products were utilized as the top and bottom membrane layers in the 5PB beams. Furthermore, in the last part of this paper, the dissipated energy has been utilized to explain the incremental damage during the testing.
