  • the present invention provides an improvement to the devices with dynamic spreading ramps described in the aforementioned application FR-90.06306. We have indeed sought to further reduce the size of these devices on the pavers.
  • the invention proposes a new spreading structure, which makes it possible to carry out continuous spreading with only two ramps over an adjustable road width, said structure being able to be stored in the width of the paver after operation, so that 'there is no problem of size during transport.
  • the present invention therefore relates to a device for spreading on the surface of a road an emulsion for attaching bituminous mixes, a bituminous fluid substance or a similar fluid substance, comprising on a mobile machine spreading booms associated with ejection nozzles as well as supply circuits of said nozzles, said booms being able to move relative to said mobile machine transverse to the direction of movement thereof, being associated with motor means intended to drive them in displacement during spreading in a back-and-forth movement, said nozzles thus performing continuous complementary dynamic spreading on the road surface, the back-and-forth strokes of certain said ramps being adjustable as a function of the width over which it is desired to spread, characterized in that it comprises two spreading ramps whose strokes are adjustable according to the width over which it is sought to spread, to allow said two booms to perform spreading together over said entire width.
  • said two ramps have ranges of reciprocating strokes substantially independent of the width of the road over which it is sought to spread, said device comprising means making it possible to adjust the starting points of the races of said ramps on said mobile machine.
  • this device comprises means making it possible to control the opening and closing of the ejection nozzles so that the spreading carried out by said two ramps does not overlap.
  • this device can comprise, for each ramp, means controlling, according to the direction of movement in which the ramp is moving, the opening or closing of the nozzles of said ramp as they pass at a particular point.
  • said tipping point fixed with respect to the mobile machine, said tipping point being substantially the same for each of the two booms, said booms spreading respectively, one on one side, the other on the other side, of said tipping point.
  • the motor means actuating a ramp are jacks whose position relative to the width of the mobile vehicle is adjustable.
  • this device comprises means of the rack type, which make it possible to adjust the starting point of the travel of a spreading ramp relative to the width of the mobile vehicle.
  • said rack type means make it possible to move the ramps and their actuating jacks.
  • a boom can comprise four nozzles spaced apart from each other by approximately 625 mm.
  • the travel of a ramp is approximately 625 mm.
  • the subject of the invention is also a pavement construction machine, comprising, on a chassis mounted on displacement means, means for spreading bituminous mixes and means for feeding said spreading means, said machine also comprising a device for spreading a bonding emulsion on the surface of a road.
  • a machine of the finisher type according to the invention is mounted on tracks 2 and essentially comprises a pilot cabin 3, a hopper 4 for receiving bituminous mixes, said hopper 4 being disposed at the front of the paver, conventional means 5 for spreading bituminous mixes which are constituted in particular by a distribution screw and which are arranged at the rear of finisher 1, a table 6 for smoothing deposited asphalt layers, as well as a device 7 for spreading a binder emulsion, associated with an emulsion supply circuit, referenced by 8 as a whole.
  • the hot bituminous mixes are transferred in a conventional manner from the hopper 4 to the means 5 for spreading the mixes via a transfer mat (not shown) placed on the finisher 1 between the cabin 3 and the part of said finisher 1 which carries the tracks 2.
  • This carpet is slightly raised in its rear part above the spreading means 7.
  • the smoothing table 6 is mounted at the rear of the finisher 1, beyond the asphalt spreading means 5, on two bent arms 9 extending on each side of the machine from substantially the middle part of the tracks to beyond the spreading means 5.
  • These two arms 9 are articulated at their end opposite to the smoothing table 6 on spacers 10 mounted at the level of the tracks 2, the inclination of said arms 9 relative to the plane of the ground determining the height of the smoothing table 6 and being adjusted by means of jacks 11 each extending between a po int of attachment on the spacer 10 and an attachment point 12 on the side of the chassis of the tractor in the extension of the floor of the cabin 3, at the rear of the latter.
  • the supply circuit 8 essentially comprises an emulsion reservoir 13 with a capacity greater than 2500 liters.
  • This reservoir 13 is disposed in the sides of the hopper 4, as has been proposed in the applicant's patent application filed under No. FR-91.06758, filed on June 4, 1991, for "Pavement construction machine of finisher type ".
  • the spreading device 7 mainly comprises two ramps 14 and 15 mounted in a casing 16 at the rear of the finisher 1. These two ramps 14 and 15 extend in parallel over two widths offset from the finisher 1, the ramp 15 being more distant than the ramp 14 from the rear of the finisher chassis. Each of these two ramps 14 and 15 is also associated with means 19, 20 intended to actuate it according to a lateral reciprocating movement relative to the direction of movement of the vehicle.
  • These means 19, 20 are for example made up of hydraulic cylinders, the rods 19a, 20a of which are connected at their free end to one end of the corresponding spreading boom 14, 15.
  • These jacks 19 and 20 are arranged respectively on one side and the other of the casing 16. The stroke of the rods 19a, 20a of the jacks is for example 625 mm.
  • the two ramps 14 and 15 are ramps which are produced in a conventional manner for those skilled in the art and are each provided with four nozzles referenced respectively, from the end of their ramp on which the rod of the jack corresponding to the free end of the same ramp, by 17a to 17d and 18a to 18d.
