高速公路沥青路面改造工程旧路面利用方案研究

Study on Utilization of Old Pavement in Asphalt Pavement Reconstruction Engineering for Highway

在高速公路沥青路面改造过程中,老路面是否保留继续利用及如何保留成为关键。以某一高速公路沥青路面为例,通过旧沥青路面性能状况的检测、分析和评价,提出了老路面改造利用方案,并取得良好效果。

The key points during pavement reconstruction for highway are whether to retain the old pavement for reuse and how to retain. Taking a asphalt pavement of a highway as an example, this paper, through test, analysis and evaluation of the performance of the old asphalt pavement, proposed a scheme for reconstruction and reuse of old pavement, and the scheme obtained a good effect.
