摘　　要：通过理论及试验研究,将旧路冷再生深度扩展到基层,通过添加泡沫沥青、水泥等添加剂,形成半柔性材料,该材料具有较好的强度、高温稳定性、水稳性和低温抗裂性。通过对试验路跟踪调查,可知半柔性路面结构可有效抵抗车辙和反射裂缝的产生。Through theory and experimental study, cold recycling of the old roads is extended to the basecourses. Semi- flexible material is formed by adding additive agent like foamed asphalt and cement, and so on, which has excellent strength, high temperature stability, water stability and low temperature crack resistance. Through the follow - up survey on the test roads, the semi - flexible pavement structures could resist rutting and reflective cracks effectively.
