水泥稳定风化山砂在城市道路基层中的研究与应用

Study and Application of Cement Stabilized Efflorescent Sand in Roadbase of Urbanroad

本文主要就敦化市所产风化山砂及其混合料的力学特性、抗冻性及路用性质进行了研究．并在上述研究的基础上，结合风化山砂在敦化市城市道路施工中的实际应用情况，提出了符合敦化市特点的风化山砂混合料配合比及典型路面结构．

The mechanical properties, antifreezing nature and utilizable property in roads of efflorescent sand and its mixture produced by Dunhua City was studied in the paper. And on the basis of this study, the mixture ratio of efflorescent sand and typical pavement structures conforming to the trait of Dunhua City was put forward, combining with the practical conditions in roadbase construction of Dunhua City,s roads.
