What is the benefit of obtaining compaction density with the paver screed?

Obtaining compaction density with the paver screed primarily helps to reduce differential compaction in low spots and rutted areas. This benefit is crucial for achieving a uniform surface, which contributes to the overall quality and longevity of the pavement. When the screed is properly set and adjusted, it can effectively compact the asphalt at consistent levels across the entire width of the paving operation. This minimizes issues that often arise from improper compaction, such as the formation of weak spots that could lead to premature failure of the pavement.

The ability to maintain proper compaction density ensures that there are no hidden areas of inadequate material density, which could compromise structural integrity. By managing these variations in compaction, the risk of future maintenance problems, such as cracking or rutting, is significantly reduced, leading to a smoother and more durable road surface.
