The other day，Located in Dabancheng District, Urumqi City, XinjiangGThe maintenance project of 3003 East Ring Expressway is in full swing.，At the asphalt construction site of Bid Section 10，Dynapac, which is simultaneously distributing and spreading emulsified asphaltSD2500CS PROTACSpreader and paver，It has become the focus of the whole construction site with its new and efficient operation ability of one machine with multiple functions.。

DynapacSD2500CS PROTACThe distribution paver was officially launched in the Chinese market at the end of 2023.，Already in South China、East China、Southwest China and other regions have participated in a number of key projects.，And has obtained the general customers high praise.，Construction in Urumqi this time，It is also the first time that this new high-tech aircraft has appeared in a key construction project in Northwest China.。

This project isGThe starting point of Line 30 is near Xiaocaohu Interchange.K3481+000，The terminal point is at Toutun River Toll Station.K3630+000，The total length of a single piece is 74.323km，The construction sections are as followK3484-K3490（Up and down）、K3572-K3587+470（Down）、K3587+470-K3600+793（Up-down local road section）、K3604-K3630（Up-down local road section），Subgrade width 33.5/42m，Design speed 100/120km/h；GLine 7 starts atK2809+000，End atK2814+000，The total length of a single piece is 10.384km，It is located at Ganquanbao Interchange，Subgrade width 42m,The design speed is 120km/h；GThe starting point of Line 3003 is Yan'an Road Interchange.K142+000，The terminal point is located at Lanxin Elevated Road.K153+000，Down section，The total length of a single piece is 10km，Subgrade width 33.5m,Design speed 100km/h。Diseases of the original pavement caused by the maintenance project、Cracks and so on have been thoroughly treated.。After milling the old pavement，Adopt 2cmOf thicknessSMA-8 High toughness asphalt mixture for ultra-thin overlay super wearing course construction。

DynapacSD2500CS PROTACSpreader and paver，Can integrate the two functions of emulsified asphalt spraying and paving，The seamless connection between the spraying and paving process further improves the performance of the road.，In particular to the construction operation of modern ultra-thin overlay asphalt paving.，Achieve ultimate flatness while improving construction efficiency。

SD2500CS PROTACEquipped with an emulsified bitumen reservoir with a capacity of up to 2100 litres，Emulsified asphalt filling port and liquid level display screen are provided on both sides of the equipment.，Very convenient for filling emulsion。The intelligent heating system of the liquid storage tank can gently heat the emulsion in stages and sections.，Convenient for heat preservation and reheating。3 spray bars spread over up to 25 atomizing spray nozzles，Ensure even distribution of emulsion。Wherein the spraying width can be changed along with the expansion and contraction of the hydraulic screed by the two infinite expansion and contraction sliding spraying rods on both sides.，Achieve the best spraying effect。

Matched with innovative asphalt emulsion spraying technology，Is Dynapac's most stable.SDFlagship paver and superior screed technology。SDStable conveying system of series paver、Advanced intelligent control system combined with 4-axis support guided screed，At the same time of intelligent control，Avoid bending or twisting the screed，Maintain excellent flatness of paving surfaces，And avoid segregation。

As an important part of the highway maintenance project of Xinjiang Communications Investment Co., Ltd. in 2024，GUp to now, the maintenance of Section 10 of 3003 East Ring Expressway has been basically completed.。Within the construction period of more than one month，DynapacSD2500CS PROTACSpraying paver once again helps customers greatly improve construction efficiency with high-tech means.，Brings excellent construction quality。

Dynapac，Always committed to providing high-tech road construction solutions to customers around the world，Lead technological change，Create an industry benchmark，Join hands with you，Build the future together！
