ABSTRACT:
A machine is provided for constructing, in particular, redeveloping, the constructional layers of roads, preferably by re-using the old material removed from the road; wherein a receiving silo for the old material, which is mounted on a chassis of a motor-driven running gear, is feedable, preferably in regulatable quantities, to a horizontal stream crusher; said crusher being in connection, via a dosaging conveying device, with a mixer, also mounted on said chassis, whereto additional material components from at least one additional tank or silo, supported on said chassis, may be fed and wherefrom the prepared material ready for distribution is fed, by way of a conveyor worm, to a screed drawn along behind said chassis. Such a machine permits, in addition to the cold recycling of asphalt, also the construction of cold-mix foundation layers as well as a stabilization and a direct distribution of practically any supporting-layer materials.
