ABSTRACT

ABSTRACT: Orthotropic steel deck bridges become popular the last decades due to lightweight 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.
