预应力混凝土桥梁桥面沥青混凝土摊铺技术

Paving Technology of Prestressed Concrete Bridge Bitumen Concrete

沥青混凝土路面具有行车舒适、噪音低、维修方便、施工工期短等优点,目前在高速公路及市政道路上被广泛应用,但其在桥梁桥面上的摊铺施工做法与普通路基应有所不同,如采用普通做法则可能对桥梁结构造成一定影响,甚至造成桥梁垮塌等严重后果,本文结合工程实例对预应力桥梁桥面沥青混凝土摊铺技术及其施工要点进行介绍。

Bitumen concrete pavement is widely applied in freeway and municipal road. But its paving construction in bridge deck and in ordinary embankment is defferent. If it uses common method,it will cause certain effect in bridge structure,even cause bridge collapse. Combined with practical work,this paper introduces paving tenhnology prstressed concrete bridge bitumen concrete and its construction points.
