甘肃省内,位于祈连山脚下的公路段,处于河西走廊的中部,自古即是交通要道,是古“丝绸之路”的重要路线,也是连接大西北的重要通道。随着近几年公路建设的加强,公路养护逐渐成为重要内容。截至2005年底,甘肃公路局的养护里程增加到了1030 km,而路面的好路率,也由2001年的70%增加到2005年的超过77%。原有的人工养护方式已经不能胜任发展的要求。
In Gansu Province, the section of the road at the foot of Qilian Mountains is located in the middle of the Hexi Corridor. Since ancient times, it has been a major thoroughfare for transportation. It is also an important route for the ancient Silk Road and an important gateway to the northwest. With the strengthening of highway construction in recent years, highway maintenance has gradually become an important part. By the end of 2005, Gansu Bureau of Highway Administration had increased the maintenance mileage to 1,030 km, while the good road surface rate increased from 70% in 2001 to over 77% in 2005. The original method of manual maintenance can no longer meet the requirements of development.
