为了研究甘肃地区Superpave路面材料的应用标准,使Superpave路面更好地与甘肃地区的实际情况结合并进行应用,通过对该地区1971～2000年的气温资料整理统计,利用LTPP气候影响模型计算甘肃地区Superpave路面高温和低温设计温度,得到甘肃地区沥青PG等级;同时结合中国及甘肃地区实际情况,对该地区沥青PG等级进行调整,提出该地区沥青PG分级推荐标准;结合天水过境高速公路及西长凤(西峰—长庆—凤翔)高速公路实体工程,对甘肃陇东地区集料进行调查,通过对集料料源特性及加工特性进行试验研究、指标分析,最终提出了甘肃陇东地区Superpave路面集料推荐标准。
In order to study the application standard of Superpave pavement materials in Gansu Province, the Superpave pavement is better combined with the actual situation in Gansu. Based on the statistics of the temperature data in the area from 1971 to 2000 and the LTPP climate impact model, Superpave Pavement temperature and low temperature design temperature, get Gansu asphalt PG grade; combined with the actual situation in China and Gansu Province, adjust the asphalt PG grade in the region, put forward the asphalt asphalt PG classification recommended standards; combined with the Tianshui Expressway and the West long Fung (Xifeng - Changqing - Fengxiang) Expressway physical engineering, the Gansu Gansu aggregate survey conducted through the aggregate material source characteristics and processing characteristics of the pilot study and analysis of indicators, and ultimately proposed in Gansu Long Superpave pavement Aggregates recommended standards.
