Gongyu Road starts from Qiabuqia Town, Hainan Autonomous Prefacture, Qinghai Province, and connects with the section of Beijing-Tibet Expressway (Gonghe Road to Chaka Road) and ends at Jiegu Town (Xinzhaidong), Yushu County. The entire road is longer than 630km with an investment of more than ten billion yuan. It crosses the permafrost regions throughout. The permafrost section is 227.7km, accounting for 35.8% of the entire route. The altitude of the entire route is above 4200m.

This first high-altitude and high-cold expressway crossing over the permafrost regions in Tibet Plateau creates a miracle in the Tibet Plateau road history. The XCMG complete road equipment that continuously works at site covers all needs for road construction, such as the paving and compaction of base stable soil, the paving and compaction of surface asphalt and roadbed leveling. A series of star products has distinguished their excellent performance on the vast and great land of Qinghai Province, such as rubber-wheel roller XP301, XP303, tandem roller XD131, single roller XS223J, grader GR180 and paver RP952. They are fearless of danger, difficulty and cold and contribute XCMG’s efforts to the successful construction of farmers and hersmen along the road and accelerating the poverty-relieving and better-off for the local people.
