《Dimensional classroom | Stroke of Rammer of Screed of Vogler Paver and Precautions》

1.The screed is the main working device of the paver.，Its compaction system is also very important for the paving effect.，The following statements about the Vogler paver screed compactor Mistake One of the items is：

A、Compactness is an index to measure the compaction effect.，That is, the proportion of the volume of the solid substance part of the material to the total volume.，The effect of compaction is generally measured by the initial and final degree of compaction。

B、The Vogler paver screed compacting device includes a rammer.、Vibrating device and pressure beam。

C、Generally speaking，Rammer+The maximum initial density of the vibrator is 75%，Rammer+The maximum initial density of one pressure beam is 80%，Rammer+The maximum initial compactness of 2 pressure beams is 85%，Rammer+Vibrator+The maximum initial compactness of two pressure beams is 95%

D、The weight of screed is the factor affecting the initial compactness of the paving layer.、Vibration function and pressure beam，The vibration function has the greatest influence on the initial compactness.。

2.In the Paver Screed Compaction Unit，The main function of the rammer is to improve the material density of the new pavement layer.，The distance that the ram head moves up and down is called the ram stroke.，One of the following statements about the ram stroke is incorrect：

A、The rammer stroke of a Vogler paver is typically adjustable to：2 mm、4 mm、7 mm、8 mm。

B、Vogler paver 2 mm Rammer stroke is applicable to paving of ultra-thin asphalt material，The thickness of paving material shall not exceed 2 cm、4 mm The stroke of the rammer can meet the paving of most asphalt materials.、7 mm And 8 mm Rammer stroke is used for paving of asphalt materials and cement concrete materials with large thickness.。

C、The stroke adjustment of rammer of Vogler paver is divided into mechanical adjustment and hydraulic adjustment.。
