摘　　要：为了满足地区交通量增长的需要,对既有高速公路进行拓宽改建成为最便捷的途径,不仅可以充分利用原有路基,还能够缩短建设周期,同时占用建设用地较少。泡沫轻质土路基处理技术是近些年我国出现的一种新型技术,实践证明其在高速公路扩建工程中的应用取得了非常不错的成效,能够改善工程施工质量,对交通运输工程的可持续发展具有十分重要的意义。IIn order to meet the needs of regional traffic growth, the widening and reconstruction of the existing expressway is the most convenient way, which can not only make full use of the existing roadbed, but also shorten the construction period and occupy less construction land. As a new type of technology appearing in China in recent years, the application of foam light soil roadbed treatment technology has achieved very good results and can improve the construction quality of the project in expansion project of expressway. It is of great significance to the sustainable development of transportation engineering.
