| Abstract: | With the increasing of traffic volume and heavy-duty traffic, there are serious early diseases in deck pavement with epoxy asphalt. In this paper, the diseases types and distribution characteristics of epoxy asphalt deck pavement are analyzed comprehensively by multi-function detection vehicle and artificial investigation. The causes of diseases are also analyzed from aspects of loading, temperature, maintenance technology and deflection of steel box girder roof. |
