泡沫沥青冷再生混合料设计与性能研究

就泡沫沥青冷再生技术进行专项试验,分析回收沥青路面材料（RAP）的级配特性,,采用间接抗拉强度（ITS）作为控制指标进行混合料配合比设计,并对冷再生混合料力学和路用性能包括无侧限抗压强度、抗压回弹模量、高温稳定性、水稳定性和疲劳特性等进行研究,为泡沫沥青冷再生技术在工程实践中的应用提供数据参考和理论依据。

Design of cold-recycled asphalt mixture and study of its performance

The gradation characteristics of recycled asphalt pavement（RAP） materials were examined by conducting the special tests with cold-recycled technology of foamed asphalt.The mix design was carried out by using the indirect tensile strength（ITS） as a control index.Also,the mechanical performance and road use of cold-recycled mixture were examined,including the unconfined compressive strength,the resilient modulus,the stability at high temperature,the water stability and the fatigue,etc,thus providing data for reference and theoretical basis for application of cold-recycled technology of foamed asphalt to pavement project.
