Late summer and early autumn，The heat gradually abated.，But road construction is still hot across the country.。In order to catch up with the delay of the epidemic at the beginning of the year,，Each road construction site is grasping this golden period to push forward the progress.。And in these high-grade pavement construction sites,，The guarantee of efficient compaction is indispensable.——Dynapac Large Double Steel WheelsCCThe figure of 6200。

DynapacCCSeries double-drum road roller，It is the best product series that Dynapac's original high-frequency vibration compaction technology has been put into practical application.。From the first generation of double steel wheel roller to the fifth and sixth generation of double steel wheel roller.，High efficiency due to high frequency resonance compaction of Dynapac roller、Quickly、Energy Saving、High quality has become the consensus in the asphalt pavement construction industry.，It's the airport.、The most widely used machine type in the compaction of high-grade pavement such as expressway.。

At present，In Hunan、Sichuan、Construction sites of several expressways in Zhejiang Province，DynapacCCThe 6200 large double-drum roller is on full fire.，Comprehensively boost the rapid progress of the project。

Jiang-Shan Expressway（Jiang Bei Zhi Gan Shan）：Hunan Province expressway network“Seven vertical and nine horizontal”Expansion line of Changyong section of the fourth middle horizontal line，Originated in Liuyang City，Stop at Ganshan, Changsha County。The high-speed main line is 21 kilometers long.，Two-way 4-lane，Design speed 100 km/Hour。At a busy construction site，5 setsCCThe 6200 double-drum roller is rumbling along.，Road surface with first-class smoothness、The quality of the bridge deck is achieved accordingly.。

Suide Expressway（Deyang City to Suining City, Sichuan Province）：Connecting Zhongjiang County of Deyang City and Daying County of Suining City，It is one of the important lines in the provincial highway network planning.，It is also one of the key transportation construction projects in Deyang City.。Total length of line: 28.67 km，Two-way four-lane，The design speed is 100 kilometers per hour。8 unitsCCThe 6200 double-drum road roller is running at full capacity to grasp the progress.，Strive to complete the project as soon as possible。

A number of expressway construction projects in Zhejiang Province are accelerated at the same time.，Dynapac Rollers in Full Bloom，More than 30 setsCC6200 double steel wheels serve the Shanghai-Kunming Expressway from Changshan to Lanxi、Section from Lanxi to Zhuji、Changtai Expressway、Shaozhu expressway and many other expressway construction sites，To accelerate the improvement of the modern highway network in Zhejiang Province。

DynapacCCThe excellent compaction performance of the series of double steel wheels benefits from the resonance compaction technology theory founded by Dynapac in the 1960s.，This theory has also led the road construction industry from static rolling to the modernization stage of dynamic compaction technology.。

The advantages of Dynapac's high frequency vibratory compaction theory are，The high vibration frequency of the tandem roller reorders the material particles at resonance，Small particles are rapidly incorporated between large particle，Squeeze out air and moisture，O as to achieve better compactness in the most efficient manner；High frequency vibration、Rapid Rolling，Minimize adverse effects due to material temperature decay when compacting thin layers of asphalt；High frequency vibration is far away from the natural frequency of bridge structure and surrounding buildings.，Ensure construction safety；Does not break aggregate，No damage to asphalt layer structure，Maximize road friction performance while delivering first-class flatness。

In the meantime，DynapacCCCharacteristics of Low Energy Consumption of Series Tandem Roller，Guarantee of low cost operation of equipment：High-speed and efficient operation，Directly brings low fuel consumption；EDCThe electronic drive control enables the vibration pump to be started at a staggered peak when starting.，Avoid the working condition of engine oil consumption；Auto Idle Control——Handle in neutral position for more than 10 seconds，The engine automatically enters the idle state.。

High-Tech Dynapac Twin-Wheel Roller，It is the guarantee of the construction quality of various high-grade pavements.，Helping to Accelerate the Modernization of China's Road Administration，Join hands with you，Building the Future Together！
