通过对黄河冲（淤）积粉土地区道路基层材料水温稳定性试验，分析常用结合料稳定粉土抗水、抗冻性能差的原因研究证明，二灰土外掺工业纯碱（ Ｒｃ）或工业水玻璃（ Ｒｓ，湿法生产），能显著提高该地区道路基层材料的抗水、抗冻性能
By analyzing the water temperature stability of the road base material in the silt-accumulated silt soil area of the Yellow River, the reasons for the poor resistance to water and frost resistance of the commonly used binder stabilized silt were analyzed. The research proved that the lime-soil mixed industrial soda ash (Rc) or industrial Water glass (Rs, wet production) can significantly improve the water and frost resistance of road base materials in the area.
