Method and device for producing a surface coating on a surface such as a road

A device for producing a surface coating, formed of aggregates and bitumen, on a surface, comprising:

• a chassis having a forward end and a rearward end;
• a plurality of rolling means spaced longitudinally along said chassis for supporting said chassis such that it can roll along a particular direction of advance;
• means for moving said chassis along said direction of advance;
• a receiving hopper mounted on said chassis near said forward end thereof for receiving chips;
• a storage hopper mounted on said chassis at a central part thereof for storing the chips;
• elevator means for conveying the chips upwardly from said receiving hopper and into said storage hopper;
• conveyer means for conveying the chips rearwardly from said storage hopper;
• at least one reservoir mounted on said chassis for containing liquid bituminous binding material;
• spraying means, mounted rearwardly of the rearwardmost of said rolling means, for spraying the liquid bituminous binding material from said at least one reservoir onto the surface as said chassis is being moved forwardly in said direction of advance;
• discharge means, disposed rearwardly of said spraying means, for discharging the chips from said conveyer means onto the surface after it has been coated with the liquid bituminous binding material by said spraying means, as said chassis is being moved forwardly in said direction of advance;
• and
• a finishing table, suspended in an articulated manner from said chassis at a location rearward of said spraying means, for compacting the chips discharged onto the surface against the binding material sprayed onto the surface as said chassis is being moved forwardly in said direction of advance.
