What is the purpose of operational vibrators on the screed?

The purpose of operational vibrators on the screed is to feed the mixture uniformly under the screed. When asphalt or concrete is laid down, achieving a smooth and consistent surface is crucial for durability and performance. The vibrators help to ensure that the material moves smoothly and evenly as it spreads, preventing segregation and ensuring a uniform layer. This uniform feeding is essential for maintaining the correct thickness and achieving better overall compaction as the screed moves along the surface.

While enhancing material temperature, improving the speed of the paver, and compacting the mix are important aspects of paving operations, these factors are not the primary role of the vibrators on the screed. Vibrators specifically address the distribution of the material, aiding in the formation of an even layer as it is laid down.
