Whether it is a new road or an old road upgrading and reconstruction.，The operation effect of compaction link is an important factor affecting the quality of surface course.，Especially in recent years, the thickness of new high-speed pavement has been increased.、New municipal roads and expressways、New materials such as modified special asphalt materials are more and more widely used in various grades of highways.，Under the new situation of construction such as shorter compaction time window，Higher requirements have been put forward for the performance of the main compacting large double steel wheel.。

Hummer responded to the situation，Integrate many R & D achievements on the basis of classic compaction models，Enlarged in the Chinese market.：A whole new generation HD Series heavy duty double steel wheels，Powerful performance shows the true qualities of bravery，Compaction speed takes the lead！

There's video, there's truth.，See Xiaowei reveal the new generation for you HD The reason why the series of double steel wheels are so powerful。

There are examples to see the strength.

· Construction site：Construction site in Qingyuan, Guangdong

· Compacted material：Asphalt concrete AC16

· Compacted thickness：8 cm

· Compaction process：60 Hz High frequency mode 3 times

· Compaction speed：5.5 km/h

Highlights：Compared with traditional roller，New generation of Hummer double steel wheel HD 138i/HD 148i Frequency from 25-60 Hz Adjustable, Can be suitable for compaction of various material。Pecially to an optimized 60 Hz When the system is vibrated at high frequency，Smaller impact clearances can be achieved during compaction operations， Therefore, it has the ability of high-speed compaction.。

In this project，The new model of Hummer with double steel wheels has achieved 5..5 km/h Compaction speed of，Efficient operation。Operation pictures from the above site during the day and at night，It can be clearly observed that the smoothness of the pavement is good.，There are no small waves.（In the past, the compaction speed of the common road roller was too fast.，Uneven compaction caused by too large impact gap）。

It turns out，While ensuring flatness，The new model of Hummer High Frequency Heavy Duty Double Steel Wheel can increase the compaction speed of the middle layer and the upper layer to 5.5-6 km/h。This performance is constructed in autumn and winter.，Ambient temperature is low，Under the condition that the material temperature drops faster per unit time，Its advantages in compaction quality will be more prominent.，At the same time, the high compaction efficiency can also save a lot of labor for customers.、Fuel and other expenses。

Wei has something to say

Wirtgen's new product promotion activities and test drive demonstration activities are in full swing in China.，Is the new model good?，Personal experience will be more real.，You are welcome to contact the local agent of Wittgen China in the region to understand and personally experience the new machine.。
