Abstract

Reliable and durable asphalt surfacing systems still are desired for long-spanned orthotropic steel bridges according to national and international reports on distresses in deck pavement. Based on ten-year research works, this paper presents a brief review and discussion of the practices and experiences of deck pavement on long-spanned steel bridges in China, including issues of typical surfacing materials and their properties, main distresses in asphalt surfacing, and the basic characteristics of asphalt surfacing on orthotropic steel bridge decks. It is concluded that the behaviours of deck pavement on orthotropic steel bridge decks under truck loads are complex as a result of geometric and material-dependent nonlinearity, coupling the global dynamic effects of the whole bridge system. More efficient computational techniques are still desirable for coupling global effects with local responses, counting the interfacial effects and interactions, and evaluating the effect of the predominant distress of fatigue cracking and de-bonding on the service life of this type of structure.
