Abstract (en)

[origin: EP0364742A2] The invention relates to a construction machine for applying a new covering to bicycle tracks, footpaths or the like. A construction machine of this type consists of a chassis (42) having a drive motor (5) and a bunker (5), arranged on the chassis, for the covering material, which is drawn off against the travelling direction via a conveyor belt (6) and is discharged in front of a tamping beam (7). Construction machines of this type are also used to repair existing old coverings, for example for closing the covering again after carrying out work on the sewers. To this end, however, manual preliminary work has to be carried out, such as, for example, cleaning of the edges and the like, which is very time-consuming and involves a lot of labour. According to the invention, provision is made for arranging a milling and mixing device (8) between the conveyor belt (6) and the tamping beam (7), which milling and mixing device (8) mills off the old covering to a predetermined width, mixes the milled-off old material with new covering material and discharges it in front of the tamping beam (7) which places the mixture as new covering. Manual preliminary work can therefore be dispensed with. <IMAGE>
