摘要
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 asphalt pavement of road in Laos, the tempera- ture and rainfall data in 10 years were collected and the change laws of them were analyzed. The asphalt pavement climate regions in Laos were divided according to the norms in China. The moisture temperature coefficient was introduced and its probability distribution was analyzed. The standard of the moisture temperature coefficient was recommended and the asphalt pavement climate regions based on the moisture temperature coefficient were determined. The results show that the main influence factors for asphalt pavement performance are high-temperature and rain- fall in Laos, and the asphalt pavement climate regions are within zone 1-1-2.2-1-2.3-1-2.3-2-1 and 3-2-2. The moisture temperature coefficient for division is determined to be 68 according to the principle of equal probability, and a climatic division map of the asphalt pavement in Laos is drawn. 3 tabs, 10 figs, 12 refs.
