摘　　要：针对西安高新区亚迪路路面网裂、车辙及沉陷等病害,根据道路检测报告,结合政府有关部门提出的缓堵保畅、治污减霾的工作要求,提出对亚迪路采用地聚合物注浆加固技术结合沥青面层现场热再生技术的养护方案,并对该方案的实施进行跟踪分析。分析表明:地聚合物加固技术结合沥青面层现场热再生技术的养护方案不仅可以实现"非开挖"式半刚性基层的补强加固,恢复沥青路面性能,且具有减少建筑垃圾、减小交通影响、降低造价的优势,并提出施工过程中应注意的事项及尚待完善的问题。Aiming at the diseases of pavement net-shaped cracking, rutting and sinking of Yadi Road in Xian Hi-Tech Industrial Development Zone, based on the road inspection report and according to the working requirements of congestion relaxing, smoothness keeping, pollution control and haze reduction issued by the relative government departments, the article puts forward the maintenance scheme of polymer grouting reinforcement technology combined with asphalt surface in-situ thermal regeneration technology used for Yadi Road, and introduces the trace analysis on the implementation of this scheme. The analysis shows that the maintenance scheme of polymer grouting reinforcement technology combined with asphalt surface in-situ thermal regeneration technology can not only realize the reinforcement of trenchless semi-rigid base, recover the asphalt pavement performance, but also decrease the building rubbish, reduce the traffic impact and reduce the construction cost. The matters for attention in the construction process and the issues to be perfected are proposed.
