What is the result of having vibrators on the screed during operation?

Having vibrators on the screed during operation significantly contributes to the improved uniformity and density of the asphalt mat being laid down. The vibrators help in settling the asphalt mix more evenly and effectively, which promotes better compaction. This enhanced compaction ensures that the asphalt mat is not only uniform in thickness but also has increased density, which is critical for the longevity and performance of the roadway. Proper density contributes to factors such as structural strength, durability, and resistance to moisture infiltration, which ultimately leads to a better quality surface.

While increased vibration can be associated with other potential outcomes, the key point is the vibrators' specific role in enhancing the uniformity and density of the mat during the laying process. This aligns with best practices in roadway construction, where achieving an optimal density is paramount for high-quality outcomes.
