摘　　要：研究沥青路面就地热再生在高原地区的适用性,有利于该技术在高原地区高速公路养护中的推广应用。通过对高原地区高速公路沥青路面就地热再生在实体工程中再生前后的回收沥青三大指标检测情况,确定了就地热再生在高原地区的适用条件。然后,通过对不同摊铺温度下压实情况分析,得出了高原地区压实温度控制范围。最后,经过对就地热再生路段运营3年后的跟踪检测,表明就地热再生技术在一定条件下,可以在高原地区高速公路养护工程中进行推广应用。The applicability of hot in-place Recycling of asphalt pavement regeneration in plateau areas was studied,which was conducive to the promotion and application of this technology in highway maintenance in plateau areas.Through the detection of the three major indicators of asphalt recovered before and after the hot in-place recycling regeneration of asphalt pavement of expressways in the plateau area,the applicable conditions of hot in-place thermal recycling in the plateau area were determined.Then,by analyzing the compaction situation at dfferent paving temperatures,the compaction temperature control range in the plateau area was obtained.Finally,after tracking and testing the operation of the hot in-place regeneration section after three years of operation,it showed that the hot in-place regeneration technology can be popularized and applied in highway maintenance projects in plateau areas under certain conditions.
