为了给六盘山地区筑路施工选择合适的沥青品种和标号,在搜集、分析六盘山地区气象资料的基础上,借鉴美国SH RP沥青PG分级方法,采用SH RP公式将气温转换为位于路表以下20m m深处的平均最高温度作为高温设计温度;低温设计温度则采用路表温度,并根据六盘山地区的具体情况进行修正,然后提出了六盘山地区沥青路面气候分区、沥青路用性能PG分级及合理选择的沥青品种和标号,旨在为六盘山地区修筑沥青路面提供一定的技术支持.
In order to select suitable asphalt varieties and labels for road construction in Liupan Mountain, based on the collection and analysis of meteorological data in Liupan Mountains, the SH RP formula is adopted to learn the classification of SH RP asphalt in the United States, and the temperature is converted to below the road surface 20m m depth of the maximum average temperature as the design temperature of high temperature; low temperature design temperature is the use of road surface temperature, and according to the specific circumstances of Liupanshan area to be amended, and then proposed the Liupan Mountain asphalt pavement climate division, asphalt road performance PG grading And a reasonable choice of asphalt varieties and labels, designed to build asphalt pavement in Liupanshan provide some technical support.
