对旧路进行加宽改造是提高既有道路等级和改善路网结构的有效措施,不仅能够解决当前投入的困难,又能快速满足日益增长的交通需求。而对旧路进行加宽改造,方案设计是决定成败的关键因素。在铺筑试验路并进行现场观测的同时,探索旧路加宽的理论分析方法,可为今后的旧路加宽改造工程提供十分有益的借鉴。
Widening and rebuilding the old roads is an effective measure to improve the existing road levels and improve the road network structure. It can not only solve the current difficulties in investment but also meet the rapidly growing traffic demand. The widening and transformation of the old road, the program design is the key factor in determining success or failure. While paving the test road and observing the scene, exploring the theoretical analysis method of the old road widening can provide a very useful reference for the widening and reconstruction of the old road in the future.
