Questions About Vibratory Compactor

A vibratory compactor is a type of heavy machinery and equipment used for road construction and maintenance, it is mainly used to compact the land, gravel, asphalt and other materials to make the road flat and strong. Common questions about vibratory compactor are as follows:

 

 

 

 

 

1. What Is The Definition Of Vibratory Compactor ?

 

Vibratory compactor is a method of using mechanical self-weight, vibration, repeated loading of the compacted material, to overcome the cohesion between the material and internal friction, to exclude the internal gas and moisture, forcing the material particles to produce displacement, wedge each other, increase the degree of compaction, so as to achieve a certain degree of compactness and smoothness of the operation of the machinery.

 

 

2. What Are The Factors Affecting The Compaction Effect ?

 

Factors affecting the compaction effect are:

a. the compressed material and its gradation; b. moisture content; c. compaction energy and construction methods.

 

 

3. Vibratory Compactor For Road Rolling, According To What Order Of Rolling ?

 

Vibratory compactor compaction operation should be the center line of the roadbed and pavement as the goal, from the left and right side of the line began to press to the center line of the trip (roller in the longitudinal length of a run for a trip), until the main wheel of the roller to the center line until the last in the road to add pressure on the main wheels are not yet according to the requirements of the pressure to the place, that is, "the first two sides, and then after the middle".

 

 

4. What Is The Compaction Principle Of Static Roller ?

 

Static roller is a static compaction principle, the use of the roller itself travelling roller on the material being pressed to carry out repeated crushing machinery. Relying on the static pressure generated by the self-weight and load of the roller to act directly on the paving layer, the solid particles of the soil and other pressed materials are pressed against each other to form a whole structure with a certain degree of strength and stability. That is to rely on the static pressure generated by the gravity of the machinery itself to complete the compaction work.

 

 

5. What Is The Principle Of Vibratory Compaction ?

 

The principle of vibratory compaction is to use the self-weight of the machinery and the excitation force produced by the shaker, forcing the compacted material to make vertical forced vibration, sharply reducing the internal friction between the soil particles, so that the particles are close to each other and the compactness is increased, so as to achieve the purpose of compaction.

 

 

6. What Is The Compaction Principle Of Vibratory Roller ?

 

The rolling wheel rolls back and forth along the surface to be compacted, and at the same time, the excitation force generated by the rotation of the eccentric mass M (vibration at a certain frequency and amplitude) makes the layer to be compacted be subjected to the static pressure of the rolling wheel and the combined effect of the vibration force at the same time, and exerts a short continuous pulsating impact to the material.

 

 

7. In The Construction Of Highways, Roadbed Soil And Pavement Paving Layer Should Be Compacted Layer By Layer, What Is The Purpose Of Compaction?

 

The purpose of roadbed soil compaction is to reduce the gap in the soil, increase the compactness of the soil, improve the compressive strength and stability of the roadbed, so that it reaches the specified load-bearing capacity; road pavement compaction is to improve the compactness of the pressed material, so that it reaches the specified degree of compaction, in order to resist the power of the vehicles and other objects travelling on it, as well as the erosion of rain and snow.
