随着公路路面使用时间的增加以及重载交通增长造成的路面早期破坏的增多，现有高等级公路已逐步进入大修阶段。为了更好地应用泡沫沥青冷再生技术，本文以西宝改扩建为例首先介绍了泡沫沥青冷再生的配合比设计，并阐述了沥青路面冷再生的施工工艺，最后介绍了该技术在路面中的性能及其评价方法。%With the increase of the service time of highway pavement and the growth of early pavement damage caused by overloading traffic, the existing highway has gradually entered the stage of major repair. In order to better apply the cold regeneration technology of foam asphalt, this paper takes Xibao reorganization and expansion for example to introduce the reconstruction technology of cold regeneration of bituminous pavement and introduce the performance and evaluation methods of this technology in the pavement.
