冷再生混合料路面基层水稳性及冰冻稳定性研究

沥青路面结构在使用初期透水性较大，雨季表面水有可能透过沥青面层进入路面基层中。在冰冻地区，由于冬季水分重分布的结果，路面基层可能处于潮湿或过潮湿状态，进入路面结构层的水分能使路面基层或底基层的强度大大降低．导致沥青路面过早破坏。通过对冷再生混合料作为路面基层进行水稳定性和冰冻稳定性研究，分析其路用性能，进而提出一个合理的冷再生路面基层结构，对于工程实践及理论研究皆有一定的参考价值。

Cold Regeneration Road Base Mixing Materials Water Stability and Frozen Stability

During rainy season, water is likely to infiltrate road-base and sub-base through the asphalt surface, the upper road and the road sub-base may be too wet or damp because of the redistribution of water in winter. The water in base can make the intensity of base and grass-roots base decrease, resulting in the early damage of asphalt pavement. The water stability and frozen stability are studied to analyze its road performance with cold regeneration mixing material as roadbase. It has a certain of reference value to construction operation and theory research.
