摘要
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.
Based on climatic data in Mt. Liupan area and using PG grade classification of SHRP of the US, average maximum temperature 20 mm beneath the surface conversed by the formula of SHRP was taken as the designed hot temperature, and the calibrated surface temperature according to the fact of Mt. Liupan area was defined as the minimum temperature. Then, the climatic region of asphalt pavement, the PG grade classification of asphalt performance and best choice for asphalt road construction were put forward for technical contribution.
