Machine laying asphalt concrete, fed by a dump truck.

A paver (paver finisher, asphalt finisher, paving machine) is an engineering vehicle used to lay asphalt on roadways. It is normally fed by a dump truck. A separate machine, a roller, is then used to press the hot asphalt mix, resulting a smooth, even surface. The sub-base being prepared by use of a grader to trim crushed stone to profile after rolling.

[edit] Concrete paving

large freeways are often paved with concrete and this is done using a slipform paver. Trucks dump loads of readymix concrete in heaps along in front of this machine and then the slipform paver spreads the concrete out and levels it off using a screed.

Asphalt pavers can be on wheels or tracks. Here is a small Blaw Knox wheel type paver on a residential street job.
