Abstract
Official abstract text for this publication.
A method for laying down a pavement in which a compaction unit such as a tamper pre-compacts the paving material with a selectable stroke and at a selectable frequency while the pavement having a selectable pavement thickness is in the process of being laid down at a selectable paving speed, the stroke of the compaction unit is automatically adjustable in response to paving parameters, such as the paving speed and/or the pavement thickness, along a characteristic curve or in a characteristic map. The compaction unit includes an adjusting mechanism which is operable during the paving operation for adjusting the stroke of the compaction unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for laying down on a substrate a pavement having a selectable pavement thickness consisting of paving material on the substrate with a screed of a road paver which comprises pre-compacting the paving material with a substantially vertical movement of a tamper bar of a compaction unit attached to the screed, using a selectable stroke and a selectable frequency for the pre-compacting while the pavement is being laid down by the screed using pa…
