G15 Coastal Expressway passes through Lianyungang、Yancheng, Nantong and other prefecture-level cities，North to Fenguan Expressway，West to Yanxu、Yanjing and Jianghai Expressway，It connects Tongqi in the south、Sutong Yangtze River Highway Bridge，Directly connect with Sunan and Shanghai。The whole line adopts the standard construction of two-way six-lane expressway.，Subgrade width: 35m，The design speed is 120km/h。The maintenance design section of this asphalt pavement overhaul isG15 Lianyungang Direction of Xuean Hub to Bufeng Hub Section of Coastal Expressway，The project mainly covers the remaining sections from Xuean Hub to Bufeng Hub.，Working pavement width 15m，The total length is half width 70.361km。

The pavement of this project is paved by double machines.：1 setPR2405 Paver and 1 setRP1253TPaverSingle spread，Total width of pavement 15m，The paving speed is 2.5m/min，1 can be paved in one day.3kmLeft and right。Super wide PaverPR2405 plays an important role in it.：

· Industry's largest size frame，Industry-leading load resistance 30%，O that the presented paving flatness is more excellent.；

· Rich end retractable configuration（ 0.75m、1.5m、2mAvailable in three sizes），It can easily cope with various complex working conditions.；

· Brand newAnti-segregation material distribution device，More uniform paving effect。

And then，ByXD133SSteel wheel rollerCompaction and finishing：

· Walk-based data model，Match the best start and stop control strategy，Realize the control curve、Pressure curve、Optimal adaptation of speed curves，And greatly improves the compaction quality in the starting and stopping stages.；

· Industry originality“Three hearts in one”Technology，Vibration exciter with non-impact structures，Low noise、Long life，And that vibration stability is good，More uniform compaction；

· Optimize the spray system，AdoptThree-stage filtration，Mixed spraying by oil and water，Spray volume is reduced by 50%，Prevent temperature drop of asphalt mixture，Continuous working hours more than doubled。

Relying onDigital intelligent construction clusterHigh security、High quality、Advantages of high efficiency，This project has realized the cluster combination.Dynamic programming，So that that construction operation combination is more flexible and changeable，And ensure uninterrupted construction day and night.，Stable and continuous construction operation can be achieved in the centralized maintenance project。On the basis of improving efficiency，It also came trueEnergy saving and emission reduction、Green and environmental protectionVision for construction。

G15 Coastal Expressway Centralized Maintenance Project with Long Road Section、There are many projects、New technology and so on.，With the successful landing of the centralized maintenance project,，And it provesXCMG Digital Intelligent Construction ClusterThe extraordinary strength of，Realized“Green+Wisdom”The same frequency resonance，Make every effort to ensure the maintenance quality of expressway with product strength，Contribute to ensure that the project is completed on time, quality and quantity。
