Paver (vehicle)

[2] In 1933 the independent float screed was invented and when combined with the tamper bar provided for uniform material density and thickness.

[1] The asphalt is added from a dump truck or a material transfer unit into the paver's hopper.

The screed takes the stockpile of material and spreads it over the width of the road and provides initial compaction.

It is towed at the end of a long arm which reduces the base topology effect on the final surface.

[5] In order to provide a smooth surface the paver should proceed at a constant speed and have a consistent stockpile of material in front of the screed.
