Li, J. (author), Liu, X. (author), Scarpas, A. (author), Tzimiris, G. (author)Light weight orthotropic steel bridge decks have been widely utilized for bridges in seismic zones, movable bridges and long span bridges. In the last three decades, severe problems were reported in relation to asphaltic surfacing materials on orthotropic steel deck bridges. Earlier investigations have shown that the bonding strength of membrane...conference paper 2013

(author)Countermeasures to the ageing of bituminous asphalt binders is a highly important topic, both for service-life extension of asphalt ‘in the field’ and for recycling old pavements (RAP) into new structures with similar functional requirements as the original structure. Usually this is achieved by applying additives that restore the adhesive and...conference paper 2014
