钢桥面铺装技术现状与发展

The Status and Development of Steel Bridge Deck Paving Technology

钢桥面铺装是目前国内外道路工程领域以及路面材料领域研究的热点和难点,相比于普通的道路铺装,钢桥面铺装要复杂的多。桥面铺装层必需要具有足够的强度、刚度、抗冲击、耐磨等力学性能,同时也要求铺装材料具有强度高、柔韧性好及耐久性优良等特性。国内桥面沥青铺装技术主要有浇筑式沥青混凝土、环氧沥青混凝土以及ERS铺装技术。

Steel bridge deck pavement is a hot spot and a difficult point in the field of road engineering and pavement materials home and abroad.Compared with ordinary road pavement,steel bridge deck pavement is much more complicated.The bridge deck pavement layer must have sufficient mechanical properties such as strength,rigidity,impact resistance and wear resistance.It also requires paving materials with high strength,good flexibility and excellent durability.Bridge deck asphalt pavement technology mainly includes gussasphalt concrete,epoxy asphalt concrete and ERS paving technology.
