乌鲁木齐至霍城路精河段管的389公里+500～391公里+500间公路,系穿行流砂地段,该路段虽用苇排防砂墙避免了流砂埋路,但路线基础在沙地上,行车仍属困难。为使行车便利,采用就地拳石铺筑了一层路面。由于沙基的松软路面石块不规则,行车跳动大,机件及油燃料损耗都厉害,驾驶人员及旅客很觉不舒适。同时,因路面过窄,往往因错车陷入沙内。又因沙滩缺水,作级配路面改善也不能保持经常坚实。1956年经职工研究,本着就地取材的原则,采用了离该段14公里处含盐粘土与离该地5公里处的天然砾石级配材料拌合,铺筑了7.5 389 km from Urumqi to Huocheng Road of Jinghe Section and 500 to 391 km +500 road run through sand-filled sections. Although the sections of the section are covered with reed-sand control walls to prevent the flow sand from being buried, the route is still on the sand. It is difficult. To make driving convenient, the use of local stone paving a layer of pavement. Due to irregular sand-based soft pavement stones, driving big bounce, mechanical and fuel loss are fantastic, drivers and travelers feel uncomfortable. At the same time, due to the road is too narrow, often due to the wrong car into the sand. Due to lack of water in the beach, grading and pavement improvement can not be maintained often. In 1956, based on the principle of local materials, 1956 years of research, based on the principle of using local materials, the natural gravel gradation material 14 kilometers away from the section was mixed with salt clay 5 kilometers away from the place to pave 7.5
