Abstract

In a system for laying down an asphalt layer made of asphalt material, and having a road paver having a screed with compacting tools, a compacting device and a mixer, an electronic material density module is provided in or for the road paver. The electronic material density module obtains data during the laying process regarding at least the actual degree of compaction of the asphalt layer produced in the area of at least one compacting tool and evaluates and/or documents these data at least for operational optimisation and/or operational monitoring of the road paver and/or compacting device and/or mixer. The data obtained is communicated to the compacting device that produces the final degree of compaction of the asphalt layer based on the data and on the actual degree of compaction determined at the screed.
