In the last issue of《Dimensional classroom》In the column，Xiaowei brought to his fans about Wittgen. HT 22 Practical skills related to quick-change tool holder，Current period《Dimensional classroom》Will introduce to you.Functions and Introduction of Screed Compaction Device of Vogler Paver。

As the main working device of the paver，When a paver is used to lay a quality pavement，The screed is especially important for paving equipment：It lays the mixture on the road surface.，And then shape and compacted.。Vogler as an expert in the field of asphalt paving，Paved high-quality surface course，It's not just flatness，Has the prominent performance in the pre-compaction degree aspect，This is inseparable from the role of the screed compaction device.。

In this issue, Mr. Liu focuses on the term of compactness, which is the exclusive term of material compaction.，That is to say, the proportion of the volume of the solid part of the material to the total volume is used to introduce the relevant knowledge of the screed compaction device that the powder is interested in.。In the actual construction process，Usually, the compactness is divided into initial compactness.（Compactness of paving layer after paving）、Final Compactness（Compactness of paving layer after compaction）。The Vogler screed compaction unit consists primarily of a rammer,、Vibration device and two-stage pressure beam。

It is worth noting that，Screeds with different compaction components can achieve different initial compaction levels.？What are the factors that affect the initial density？Click on the video below to learn together!！In the next video, Xiaowei will introduce the application and adjustment precautions of the rammer stroke.，Stay tuned。

《Dimensional classroom》It is a video column produced by Wittgen China Technology and Training Center to introduce equipment operation and precautions.，Launch on a regular basis，I hope you will continue to pay attention.。In addition，If Uyghur fans have questions they want to know，You can also leave us a message.。
