摘要: 为使沥青路面结构更好适应本区域气候特点,达到延长道路使用寿命和保持路用性能的目的,对辽宁沥青路面的主要损坏形式、损坏原因和影响辽 宁省干线公路路用性能的主要气候因素详细分析。分别采用累年极端最高气温、累年极端最低气温和累年极端年降水量作为分区指标,基于聚类分析法通 过3个分区指标值将辽宁沥青路面气候划分为5个区域,分别为:水稳区(Ⅰ区)、低温抗裂区(Ⅱ区)、高温稳定和低温抗裂区(Ⅲ区)、高温稳定性区(Ⅳ区) 、高温稳定和水稳区(Ⅴ区)。并结合区域行政界限在ArcGIS平台绘制辽宁省沥青路面气候分区图,得到各区域指标数值分布情况。

Abstract: In order to make the structure of the asphalt pavements more adapt to the climate of a certain region to achieve the purpose of extending the service life of the road and keeping the road performance, the main damage forms of asphalt pavement, the causes of damage and the main climatic factors affecting the performance of main road in Liaoning province were elaborated in detail. The climate of the asphalt pavements in Liaoning province was divided into five areas according to the clustering methodology by three zoning indexes such as the annual extreme maximum temperature, the annual extreme minimum temperature and the extreme precipitation. The above five areas included the water stability area (I), the low temperature anti-cracking area (II), the high temperature stability and low temperature anti-cracking area (III), the high temperature stability area (IV) as well as the high temperature stability and water stability area (V). Combined with the regional administrative boundaries, the climate zoning map of the asphalt pavements in Liaoning province was drawn on ArcGIS platform, and the numerical distribution of each regional index was obtained.
