  • pavement repair materials such as bituminous mixes or gravel
  • Such vehicles of a type already known are advantageously arranged to constitute a single road train whose constituent elements are adapted, in a non-interchangeable manner, depending on whether it is a question of depositing on the pavement a bituminous mix or gravel amalgamated by a binder.
  • the material deposited on the roadway is compacted by the passage of a third vehicle, consisting of a compactor roller.
  • the aforementioned road vehicles constituting a single train, make it possible to resolve many of these drawbacks by bringing together on the same vehicle, both a tank of attachment product and its distribution ramp, and a device for receiving the material, as bituminous mixtures or gravel, routed by a transfer device to a distribution member on the road, which is arranged after the distribution ramp for bonding product.
  • Such an arrangement makes it possible to avoid drying of the bonding layer in ambient air before application of the repair material, occurring when this application occurs after a more or less long time, and in general, makes it possible to limit damage to the bonding layer.
  • this arrangement makes it possible to combine two vehicles into one. But, nevertheless, it does not eliminate the need to have an independently compacting roller having to pass behind said vehicle in a haze not allowing the drying of the deposited material, to obtain better compaction thereof.
  • the object of the present invention is to remedy this drawback and for this purpose relates to a road vehicle.
  • the road vehicle is characterized in that the chassis comprises a part situated at the rear of the material distribution member, mounted on rollers or balls, independently of the rolling elements connected to the motorization assembly and mounted on a front part of the chassis, and on which is arranged at least one of the members that are the power unit, the reservoir, and the control and transmission means, so that their own weight is exerting on this rear part of the chassis makes it capable of constituting a compactor of the materials spread on the roadway.
  • an autonomous motor vehicle comprising the three aforementioned functions which operate successively with perfect regularity. This has the effect of improving the quality of the coating.
  • a vehicle is powered during work thanks to an adequate arrangement of the material receiving device, thus avoiding any downtime due to loading.
  • the present invention also relates to the following characteristics, considered in isolation or in all their technically possible combinations:
  • the rear and front parts are separate to form two chassis, connected together by articulated connection means.
  • the vehicle comprises a front chassis and a rear chassis.
  • the rear chassis loaded by weight to form a compactor is thus towed by the front chassis.
  • the rear chassis supports the motorization assembly and the latter is connected to the rolling elements of the front chassis by means of a universal joint transmissions.
  • the weight on the rear chassis can also be obtained by the presence on the latter of the tank or of the control or transmission means, or all at the same time.
  • the engine assembly is connected to the rolling elements of the front chassis by means of a hydraulic transmission.
  • the motorization assembly essentially consists of a heat engine and ensures, by means of the hydraulic control and transmission means, also supported by the rear chassis, the running of the vehicle according to a preset working speed.
  • the material receiving device is arranged on the front chassis of the vehicle.
  • the material distribution member on the roadway is disposed at the rear part of the front chassis, immediately in front of a first roller or ball of the rear chassis forming a compactor.
  • the transfer device connects the device for receiving the material to the device for distributing said material.
  • the attachment product distribution ramp is arranged immediately before the material distribution member on the roadway.
  • the distribution member is a helical screw on which the bituminous mixes are brought via the transfer device.
  • the rear chassis comprises three rollers or balls, the first two of which are laterally telescopic to adapt to the width of the roadway, and the third is arranged transversely to the vehicle and fixedly in translation .
  • the distribution member is constituted by at least one hopper equipped with gravel spreaders and loaded at its upper part, by its larger opening. , in gravel brought in via the transfer device, its narrower lower part being located near the roadway.
  • the road vehicle is shown in Figure 1 during its implementation on a roadway 1, on which is deposited a layer of bituminous mixes 2 successively to a bonding layer 3 consisting of a bituminous emulsion.
  • the road vehicle moving along arrow F is refueled by means of a truck 4 dumping the contents of a tilting skip 5, constituted in this case by coated materials, in a hopper 6 constituting a device for receiving coated materials. on the vehicle.
  • the receiving hopper 6 is arranged on a front chassis 7 of the vehicle carried and driven by tracks 14. From the hopper 6, a transfer device 8, constituted by a conveyor with chains and steel bars, raises the material to a spill hopper 9.
  • the spill hopper 9 is located near the rear of the chassis 7, above a receiving hopper 10 from a finisher 11.
  • the finisher 11 is constituted, in a known manner, by the receiving hopper 10 arranged so as to pour the material onto a helical screw 12 and transverse constituting, in the present embodiment, a member for distributing the material on the roadway 1
  • An application table 13 for the coated materials is placed immediately behind the distribution member or screw 12, and has the role of smoothing the layer 2 of the coated materials according to a predetermined thickness.
  • the application table 13 is suspended from the rear part of the front frame 7 at a height adjustable by hydraulic cylinders (not shown).
  • the front chassis 7 carries a device 15 for essentially distributing attachment product 3 consisting of a ramp 16 disposed immediately before the distribution member 12, in the direction of travel of the vehicle.
  • the vehicle is also equipped with a longitudinal flat device (not shown) acting on the basis of information supplied by feelers for example.
  • the vehicle comprises a second chassis 17, connected to the rear of the front chassis 7 by means of a hinge 18 disposed at the end of an arm 19.
  • the rear chassis 17 is mounted, in the present exemplary embodiment, on three rollers or balls 20 independently of the rolling elements of the front chassis 7 constituted by the tracks 14. In other words, the rear chassis 17 constitutes a trailer to the front chassis 7.
  • the rear chassis 17 carries the motorization assembly 21, which is essentially constituted by a heat engine known per se, and which ensures by means of hydraulic control and transmission means 22, 22A also supported by the rear chassis, the running of the vehicle by driving the tracks 14 at a preset working speed, from a driving position 24.
  • the motorization assembly 21 which is essentially constituted by a heat engine known per se, and which ensures by means of hydraulic control and transmission means 22, 22A also supported by the rear chassis, the running of the vehicle by driving the tracks 14 at a preset working speed, from a driving position 24.
  • the engine assembly 21 is connected to the rolling elements or drive tracks 14 of the front chassis 7 by means of a cardan or hydrostatic transmission 23, in a manner known per se and which will not be described here.
  • the chassis 17 also carries a reservoir 25 of attachment product 3 or bituminous emulsion comprising reheating means (not shown).
  • the reservoir 25 feeds, via the conduits 26, the spreading ramp 16 mentioned above.
  • Several ramps 16 can be arranged on the vehicle and act simultaneously at varying angles and lengths depending on the pavement to be treated.
  • the first roller 20a of the thus produced compactor is located, in the direction of travel of the vehicle, immediately after the finisher 11. Also note that all the constituent elements of the vehicle has a ground speed absolutely identical, constant and regular, and constitute a single road train behind which the passage of any other type of vehicle is not necessary.
  • the helical screw 12 constituting the asphalt distribution member 2 is laterally telescopic so that it can be adapted to the width of the roadway. Its length is thus variable between a width L equal to the width of the vehicle and a maximum width L1 of extension.
  • the length L is variable for example between 2m50 and 4m50.
  • the application table 13 of the paver 11 is laterally telescopic for reasons identical to those mentioned above, but preferably the length of extension L2 chosen will be slightly greater than the length L1 of spreading so as not to leave any trace behind its passage.
  • each roller 20 a and 20 b is designed to be able to be moved laterally, on either side of the chassis 17 towards opposite positions A and B on either side of the vehicle axis, the third roller 20 c and the dead weight 40 remaining fixed in translation transverse to the axis of the vehicle and closing the step thereof.
  • the embodiment shown in Figure 3 is particularly suitable for repairing roads by spreading gravel 30, successively spreading a layer of binder 31.
