Mangya City is under the jurisdiction of Haixi Mongolian-Tibetan Autonomous Prefecture of Qinghai Province.，It is located in the northwest border of Qinghai Province.，Western margin of Qaidam Basin。The average altitude here is 3000 meters.，Precipitation is scarce throughout the year、Dry and cold、Lack of oxygen、Solar radiation is strong、The temperature difference between day and night is large、 Gale 、Severe extreme weather such as sandstorms occurs frequently.，It belongs to the typical continental desert climate.。

As of May 31，Huang-Mang Expressway（Huanggualiang to Mangya）Medium grain asphalt concrete for pavement works of highway project(AC-20C)The paving of the test section of the lower layer was successfully completed.，This indicates that the Huang-Mang Expressway project has formally entered the stage of pavement construction.。Under extremely harsh construction conditions，DynapacSD2550CSPaver with superior performance and stability，It has become a shining star on the construction site of plateau desert.。

The construction party of the Huang-Mang Expressway Pavement Project——Qinghai Traffic Control Group，He is a loyal user of Dynapac brand for many years.。On the selection of paving equipment，Qinghai Traffic Control Group, especially for Dynapac's top-end models,——SDSeries of flagship pavers are trusted。In recent years, the Traffic Control Group has successively purchasedSD2530CSOne paver，SD2550CSFour pavers。

The source of trust comes from the professional vision and rich experience of the construction party.，Traffic Control Group is well aware of the harsh working conditions in most areas of Qinghai Province.，The test of the equipment is not only the frequent raging winds.、Pervasive sand and dust，It also affects the power of the equipment all the time.、Hydraulic、Low temperature and high altitude of electrical and other systems：According to research statistics，For every 1000 meters of elevation rise，Equipment efficiency will be reduced by 15 percent%Left and right。In this case，Power shortage is common in similar equipment、Black smoke、Drop speed, etc“Altitude sickness”。

Under extreme natural conditions，DynapacSDThe paver has brought its excellent performance into full play in the plateau construction projects over the years.，Whether it's a high altitude above 4000 meters.、Tundra，Or the uninhabited Gobi Desert?，DynapacSDThe paver always brings stable attendance with its abundant power.。
