本文通过在通化地区公路养护过程中对路面结构使用的调查分析,找出对季冻区路面采取预养护的优势,并针对路面预养护方法和应该注意的事项做出分析。通化地区地处北温带大陆性季风气候区,四季气候变化分明。冬季长达5个月,严寒而干燥,夏季炎热而短促。历年最高气温36.1℃,最低气温-38.7℃,历年最长冰冻期183天,最大冻土深度1.5米,最大积雪厚度52厘米,最大降水量1130.6毫升。由于温差大,对公路使用质量和使用状况造成了非常大的影响,产生多种病害。

Through the investigation and analysis of pavement structure use in Tonghua highway maintenance, this article found out the advantages of taking preventive maintenance in seasonal frost region, and analyzed the method of road preventive maintenance and the matters that should be paid attention to.
