Paver

A Paver is also known by various other names such as asphalt finisher, paver finisher. The job of this road building machine used to lay asphalt on roadways and bridges and various other commercial and residential parking lots for similar work. Paver helps in providing a smooth, consistent surface behind the screed. It is used before roller compactor come into play.
