Jiangxi Shangrao Automobile Proving Ground

Curved surface construction with high difficulty

Jiangxi Shangrao Automobile Proving Ground Project Investment 2.2 Billion，It covers an area of about 6165 mu.，Construction has 7.2km high-speed loop，Dynamic square with a diameter of 300 meters，It covers 460 mu of intelligent network test area and nearly 100 mu of special roads.。After completion，Will have the world's first 5GIn the intelligent network test area of the network, the cross section of the curve section of the high-speed loop, which is the most difficult to construct, is designed as a cubic parabola.，Maximum inclination of curved surface 44.43 degrees,It is one of the top three large inclination angles in China.。High speed is 3D curved surface，Information system and effective technological measures must be adopted to control the paving accuracy in real time in the process of paving with large inclination change.，Overcomes the problem that the pavement material is easy to slide due to dead weight。 

The difficulty of surface compaction is the key point of surface quality control，It is difficult to balance the weight of ordinary double steel wheels.，Complete uniform compaction，And this project uses4 BMW units BW154AD-5 AP EquippedAMAsphalt Management Expert's Double Steel WheelsTo complete the asphalt compaction of the surfaces。

Best solution for road construction

Asphalt compaction is highly specialized and varies from one actual job site to another，BMG offers three different compaction systems for this purpose：Double shock、Concussion、Asphalt management expert。

Jiangxi Shangrao Automobile Proving Ground Project，Used the most powerful BMW-Asphalt management expert，The driver only needs to select the fully automatic construction mode.，The rest of the work is done by asphalt management experts.。 

In Surface Compaction，Only the fully automatic working mode is required.，Provide the degree of compaction in real time、Asphalt temperature and working speed information，Guide the construction personnel quickly、High quality finish and uniform compaction，At the same time, when the work is close to the standard value,，The system will gradually and automatically reduce the amplitude.，Avoid overcompaction。

In addition to the fully automatic operating mode，Asphalt management experts also offerManual working mode and professional full-automatic mode，Manual operating mode selectableAmplitude output direction of 6th gear，Select gear 1 when working on the bridge deck and near the building，That is, horizontal vibration，Applicable working condition range：Construction on the bridge deck、Close to buildings、Thin surface layer、At the seam；Professional fully automatic mode for experienced users，Depending on the thickness of the mat，Self-setting of mixture characteristicsEVIBStandard value。When the preset standard value is reached during operation，The system automatically reduces the amplitude，Achieve the best quality with the least number of passes！

RealizationOne machine for multiple purposes，To digitize、Intelligent、Intelligent construction solutions，Meet various high-speed loops of the test site、Multi-scene application of dynamic square and special curved surface construction。 

The ultimate experience of curve galloping

Maximum Inclination 44.43 degrees，Experience flying around the corner-Jiangxi Shangrao Automobile Proving Ground High-speed Ring Road Sets up Stage for Extreme Test。Process informatization，Accurate paving，Experience the ultimate speed of life！After the completion of the high-speed loop, the maximum test speed is 240 kilometers./Hour，Provides reliability and stability testing of the vehicle at continuous top speed。At this speed,，You will experience the vertigo of eccentricity.。
