Why does the same paver produce different smoothness results?

When different construction teams work on the same road section, why does the smoothness vary?
The cause must lie with the paver! So here’s the question:
Which method delivers better smoothness—using a single paver with extendable screed plates or two pavers working simultaneously?

  1. First, a single paver ensures maximum road smoothness. In other words, it guarantees consistency in the cross-slope across the entire road section. A single machine has an absolute advantage in this regard.
  2. Second, it eliminates the hot joint between two machines. No matter how well the joint is treated, it remains prone to water seepage and longitudinal cracking over time.
  3. Finally, using one machine reduces certain costs.

The drawback of a single paver is slightly lower efficiency and more complex site transitions. Unless pressed by tight deadlines, prioritize using a single paver for the entire project.
