为了研究老挝公路沥青路面气候分区,收集了老挝多个省份10年的温度和降雨量资料,分析了温度与降雨量的变化规律;参考中国规范,划分老挝公路沥青路面的气候分区;引入湿热系数,并分析其概率分布状况,推荐分区标准及基于湿热系数的老挝公路沥青路面气候分区。研究结果表明:影响老挝沥青路面使用性能的主要因素为高温和降雨量,沥青路面气候分区属于1-1-2区、2-1-2区、3-1-2区、3-2-1区、3-2-2区;按照等概率原则确定的老挝分界湿热系数为68,并绘制了基于湿热系数老挝的沥青路面气候分区图。
In order to study the climate division of Lao PDR asphalt pavement, we collected the data of temperature and rainfall over 10 years in several provinces of Laos, analyzed the variation law of temperature and rainfall, classified the climate division of Laos highway asphalt pavement with reference to Chinese norms, , And analyzed its probability distribution, recommended zoning standards and humidification coefficient of Laos road asphalt pavement climate division. The results show that the main factors influencing the service performance of asphalt pavement in Laos are high temperature and rainfall. Asphalt Pavement Climatic Zone belongs to 1-1-2, 2-1-2, 3-1-2, 3-2-1 District 3-2-2 area. According to the principle of equal probability, the coefficient of dampness of the Lao PDR is 68, and the map of the climate of the asphalt pavement based on the coefficient of moist heat of Laos is drawn.
