青海高寒地区沥青路面混合料配合比设计

Asphalt pavement mixture ratio design in the alpine region of Qinghai Province

本文结合青海高寒地区的特殊自然条件及G214共和—过路岭试验段,通过对所用原材料和矿料级配对比的试验分析,研究适合于青海高寒地区沥青路面混合料配合比的设计,对今后高寒地区公路沥青路面设计和施工提出了一些建议。

Combining with the special natural conditions of the alpine region in Qinghai and a mountain ridge testing section of Road G214 in Gonghe,an asphalt pavement mixture suitable for the alpine region in Qinghai was designed,and the raw materials and the mineral aggregate ratio were also analyzed.The result has certain reference value for the design and the construction of asphalt pavement in the alpine region in the future.
