摘　　要：文章构建了一个完整的冷再生沥青路面结构设计方法,提出了冷再生沥青路面结构设计应当遵循的原则;建议了冷再生沥青路面上表面层的最小厚度,冷再生沥青路面材料的分类,冷再生沥青路面的表面层、再生层和基层的结构组合;阐明了冷再生沥青路面再生层的厚度可以采用改建路面设计的方法计算确定,给出了常用冷再生沥青路面材料厚度设计图。A comprehensive method for the structural design of cold reclaimed asphalt pavement （RAP） is developed in this paper. In the development of the method, principles for the design are established. Based on the principles, the minimum thickness of the surface course over the cold-recycled base, the classification of cold RAP materials, and a three-layered structural system are described. It is indicated that the thickness of the cold RAP layer can be determined with procedures similar to those of designing overlays. Finally, design charts are provided for the convenience of thickness determination of common RAP materials.
