Abstract (en)
[origin: EP0493664A1] A method for laying-down courses of road building material by a mobile finisher provided with a compaction-aggregate, preferably a tamper, and a finisher of this type are described, the frequency of the compactor drive being adjusted as a function of a predetermined laying-down speed and predetermined parameters of the course to be laid down. To avoid irregularities in the course to be laid down, in particular during start-up, it is proposed that the actual laying-down speed be measured by a sensor and the frequency of the compactor drive be altered automatically in accordance with a preset desired-value curve if the actual laying-down speed differs from the predetermined speed. <IMAGE>
