冰雪路面砂盐混合料养护技术与标准研究

A Study on Techniques and Standards of the Maintenance forIce- Snow Road with Mixed Material of Sand and Salt

撒砂和撒盐是我国目前对冰雪路面进行抗滑养护的主要措施，但这两种方法均不理想。通过实测试验，对砂盐混合料的作用机理和使用效果进行分析，可知砂盐混合料是较砂和盐更为有效、合理的一种养护材料。在此基础上对混合料中的砂、盐质量提出了要求，并给出了混合料的合理撒布剂量。

Sand and salt scatterings are the present two main measures taken in the maintenance ofthe ice -- snow roads in our country, but the problem lies in that both of them are not the ideal methods;Through experiments and analysis of the functional mechanism and the effects of this mixed material ofsand and salt, it is concluded that this mixture is more effective and reasonable than sand or salt. Onthe basis of this, requirements are given to the quality of sand and salt in this mixture and the reasonable scattering amount is also stated here.
