Large-curvature bridge asphalt framing construction method
The invention discloses an asphalt framing construction method for a large-curvature bridge, belongs to the field of bridge construction, and aims to reduce transverse deviation of a steel bridge due to heating, in field construction, paving construction is performed in a framing manner by taking each 1.5 m as a paving width, interval construction is performed, and the steel bridge is prevented from being damaged due to large-area contact with poured asphalt. The steel bridge is heated intensively to cause overlarge lateral deviation. The cast asphalt pavement after construction is required to be compact and flat on the whole, free of water seepage, good in bonding with a steel plate and free of a bumping phenomenon; the scattered broken stones are tightly embedded and squeezed, and no threshing phenomenon exists.
本发明公开了一种大曲率桥梁沥青分幅施工方法，属于桥梁施工领域，为减少钢桥受热发生横向偏移，现场施工采用每1.5m作为一个摊铺宽度，分幅进行摊铺施工，并进行间隔施工，避免钢桥因大面积接触浇筑式沥青，钢桥受热集中造成横向偏移过大。施工完成后的浇筑式沥青路面要求整体密实平整、不渗水，与钢板粘结良好无起包现象；撒布的碎石嵌挤紧密，无脱粒现象。
