摘　　要：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 standards of the Superpave pavement materials in Gan- su region, to adapt Superpave pavement to the actual situation in the Gansu region better, the high and low design temperatures of Superpave pavement in the Gansu region was investigated based on the data of temperature in Gansu province from 1971 to 2000, the asphalt PG grade in Gansu region was gotten by using the LTPP climate impact models, at the same time the asphalt PG rating in Gansu province was adjusted based on the actual situation of China and Gansu re- gion, and the recommendation of the asphalt PG classification in Gansu region was put forward. The Tianshui transit expressway and Xichangfeng expressway actual project were taken as exam- ples to investigate the aggregate in eastern Gansu, experimental study and index analysis on the properties and processing characteristics of the aggregate material were conducted, and finally the Superpave pavement aggregate recommendation in eastern Gansu was proposed. 6 tabs, 7 figs, 13 refs.
