泡沫沥青冷再生技术在旧路改造中的应用

Application of Foam Asphalt Cold-regeneration Technique in Rebuilding of Old Road

该文重点探讨了泡沫沥青产生机理以及泡沫沥青混合料特性,分析了利用泡沫沥青混合料作为基层的路面结构的受力特性,说明泡沫沥青冷再生技术应用于旧路改造,对优化路面结构受力,降低路面结构对重载交通的敏感性,延长路面结构使用寿命具有十分重要的意义,可在我国旧路改造工程中推广应用。

The article focus probing into the produced mechanism of foam asphalt and the characteristic of foam asphalt mixture, analyzes the bearing characteristic of pavement structure by using the foam asphalt mixture as the base, and explains the application of foam asphalt cold-regeneration technique in rebuilding of old road has the very important significance to optimize the pavement structure bearing, to reduce the sensitivity of pavement structure on the heavy-loaded traffic and to lengthen the service life of pavement structure and able to be spread and applied in the old road rebuilding engineering of China.
