Machine for redeveloping the constructional layers of roads

A machine for constructing a road layer through reuse of old material removed from a road, comprising:

• a motor whose heat is transferred by means selected from the group consisting of a cooling-water circulation system and an exhaust flow system;
• a chassis for said motor, said chassis being of box-like construction and divided into a plurality of tanks for fuel, additives and hydraulic oil;
• a silo for receiving said old material, said silo being mounted on said chassis;
• a horizontal stream crusher having a major longitudinal axis through a length thereof, said axis being directed parallel to said road layer, said crusher feedable with said old material in regulatable quantities from said silo, said crusher having associated therewith a means for feeding said old material in regulatable quantities from said silo;
• a mixer mounted on said chassis having an opening for receiving said old material at an upper end thereof distant from said road layer and said mixer being subjected to heat exchange by said heat transfer means;
• a dosaging conveying device comprising a scraper band positioned between said crusher and said mixer, said scraper band being angled upward above said crusher with an end of said scraper band terminating over said opening of said mixer;
• a screed drawn along behind said chassis;
• and
• a conveyor worm between said mixer and said screed capable of feeding prepared material ready for distribution therebetween.
