| 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。

| Abstract: | Through theory and experimental study,cold recycling of the old roads is extended to the base courses.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. |
