Recently，Zhonghua Street, the main north-south road in Shijiazhuang City, Hebei Province, has been upgraded.，Located on Zhonghua North Street“Micro overlay”On the asphalt construction site，Dynapac Hi-tech Paving and Compaction Equipment，Promote the smooth progress of the project。

The construction project of North China Street adopts modern road maintenance technology.“Micro overlay”Technology，Also known as micro-surfacing overlay technology，The structure is composed of a surface wear-resistant layer and a bonding waterproof layer.，Thickness is only 1cm。Facing the high requirements of construction technology，Hongshengda Road and Bridge Company, the construction unit, chose two sets of Dynapac.F2550CSPaver+CCCombined operation of 6200 double-drum roller，And these two sets of Dynapac gold combination also live up to the trust.，Repay the trust of customers with high-quality paving and compaction effect。

In recent years，As China's road industry gradually turned to maintenance-oriented.、Phase supplemented by new construction，1.5cm-2.5cmThin-layer overlay construction technology has become a common preventive maintenance construction technology.，And“Micro overlay”It goes further on this basis.，Thickness is only 1cmEven 0.7cm。Extremely thin layer of asphalt，The requirements for the flatness of paving equipment are particularly stringent.，DynapacF2550CSPaver provides high-quality paving surface and stable operation output，Is catering to the needs of the project。

F2550CSPaver，It is designed and launched by Dynapac for the Chinese market in recent years.FTop model in the series of high-tech paving equipment。It inherits the excellent performance of Dynapac patented four-axis support floating screed.，Increase the design of the whole machine adapted to the characteristics of the Chinese local market，DynapacF2550CSIn the three years of listing, it has won the praise of the vast number of users.，After upgrading the fourth national standard，With its better power, energy saving and environmental protection, it has become the backbone of Dynapac paver pedigree.。

AndF2550CSPaver combined construction，It is the flagship product of Dynapac.——CC6200 Large Double Steel Road Vibratory Roller。For“Micro overlay”Extremely thin asphalt laminated solid construction，CCThe absolute advantage and significance of 6200 lies in：

1. High Frequency and Low Amplitude Vibration Compaction Technology——Does not break aggregate、Maximize the friction performance of the road surface，Maximize compaction efficiency；2. Unique soft start-stop function——It can ensure smoothness and uniformity without stacking when rolling extremely thin surface layer.；3. Overall layout with excellent articulated design，And the left and right sides of the front and rear wheels are provided with the reasonable arrangement of the driving motors.——In the turning process of rolling the ultra-thin asphalt layer,，It can effectively avoid the phenomenon of cracking the road surface.；4. Intelligent sprinkler system——By precise watering control，Has a positive effect on reducing the temperature of the ultra-thin asphalt layer。

Dynapac Compaction Paving Equipment with Excellent Performance，It is a high-tech solution in modern road construction technology.。Dynapac，Spare no effort to create value for customers，Join hands with you，Build the future together！
