| 摘 要： | 为了了解中国气候条件对沥青路面水损害的影响情况，对沥青路面水损害研究成果进行了回顾与分析，认为影响沥青路面水损害的主要气候因素为：降水、高温以及冻融循环过程。降水与高温过程组合以及降水与冻融循环过程组合是影响沥青路面水损害的两个主要气候过程。针对这两个主要气候过程，构建了降水气温指数和降水冰冻指数，用于评价上述气候过程对沥青路面水损害的影响。分析结果表明：利用降水气温指数和降水冰冻指数划分中国公路沥青路面水损害气候影响分区是合理可行的；根据各个气候指数的工程意义和等概率原则，确定了分区界限，拟定了包含14个区的分区方案。

| Abstract: | The specific climate zoning for moisture damage of asphalt pavements in China provides a reference for test choice and moisture damage mitigation practice. Through analysis, the precipitation, high temperature and freeze-thaw are recognized as related climatic factors. And high temperature with rainfall and freeze-thaw with precipitation are the major climatic processes affecting moisture damage. Rain-temperature index and precipitation-freezing index are constructed to respectively indicate the influence of the two climatic processes. It is properly to divide China climatic zoning for moisture damage of asphalt pavements by these indices. According to boundaries of regions, which are formed with engineering meanings of those indices or equal probability principle, China climatic zoning for moisture damage of asphalt pavements is carried out, which includes 14 regions. 3 tabs, 6 figs, 12 refs. |
