Thermal regeneration construction method for asphalt mixture pavement
The invention relates to a thermal regeneration construction method for an asphalt mixture pavement. The method comprises the following steps: cleaning a pavement, and heating the pavement to soften an old asphalt mixture layer of the pavement; raking the softened old asphalt mixture layer, and spraying a regenerant and hot asphalt; collecting the old asphalt mixture into a strip shape and performing stacking to obtain a regenerated old asphalt mixture; heating the recycled old asphalt mixture again, and increasing the temperature of the recycled old asphalt mixture; adding a new asphalt mixture into the recycled old asphalt mixture, and performing heating and uniform stirring to obtain a recycled asphalt mixture; conveying the recycled asphalt mixture to a paver for paving construction; performing a recycled asphalt mixture rolling process and pavement joint treatment; and opening the traffic after the pavement is inspected to be qualified. According to the asphalt mixture hot in-place recycling process, the old asphalt mixture of the pavement can be repeatedly used, and resource waste and environmental pollution are reduced.
本发明涉及一种沥青混合料路面热再生施工方法。其包括以下步骤：清扫干净路面，对路面进行加热，使路面旧沥青混合料层软化；对软化后的旧沥青混合料层进行耙松，喷洒再生剂及热沥青；并将旧沥青混合料收集成带状堆放，得到再生旧沥青混合料；对再生旧沥青混合料进行再次加热，提高再生旧沥青混合料的温度；向再生旧沥青混合料添加新沥青混合料，经加热搅拌均匀后，得到再生沥青混合料；将再生沥青混合料输送至摊铺机进行摊铺施工；再生沥青混合料碾压工序及路面接缝处理；路面经检查合格后，开放交通。本发明的沥青混合料就地热再生工艺，能够对路面旧沥青混合料重复使用，减少资源浪费和环境污染。
