Abstract: A method of compacting asphalt material having a mix of coarse and fine grains includes providing a paver which has, as compaction assemblies, two strip-shaped tampers which are arranged one directly behind the other in the direction of travel, each tamper being provided with a metering slope and each tamper being provided with a tamping surface thereon, each tamper being vertically reciprocated between an upper and lower terminal position, so as to cause the front tamper lower position to correspond substantially to the rear tamper upper position, whereby coarser grains in the asphalt mix are embedded and undergo minimal longitudinal displacement, as the paver moves.

Abstract: The invention relates to a road finisher having traveling gear and a series of units which are used for the consolidation of warm packing material, the finisher having a plurality of control circuits for controlling various functions performed by the machine. Each control circuit includes a replaceable control processor therein, each control processor being adapted to replace any and all other control processors and to perform any and all control functions of any and all other control processors, whereby, when a control processor fails in service, another control processor, which is controlling a less important function, can be substituted therefor to permit continued operation.
