| 摘 要： | 在水泥混凝土路面上撒大量NaCl晶体，可以起到融化积雪的作用，但是长时间之后，路面会出现砂浆松散、露出骨料的现象。通过分析路面盐冻破坏的机理，提出解决盐冻破坏的主要措施，可为以后的施工及养护提供参考。

| Abstract: | Sprinkling a lot of NaCl crystals can melt snow, but after a long time, some phenomena like mortar loosening and aggregates emergence appear in the pavement. By analyzing the mechanism of salt frost damage, the main measures of preventing salt frost damage are put forward, which can provide references for future construction and maintenance. |
