Definitions

  • the present invention relates to a device for spreading an emulsion for attaching bituminous mixes on the surface of a road, as well as to a paver construction machine of the finisher type comprising such a device.
  • this device does not in any way prevent the tracks of the paver from rolling in the bonding layer, and this precisely in the parts of said bonding layer which are subsequently the most stressed.
  • the spreading booms with multiple orifices used on conventional binder spreaders prove, in practice, totally unsuitable for this new device: the spreading on the ground of the usual quantities of binder - quantities which are relatively low (300 g per m2 to 1.2 kg per m2) - is achieved by moving the spreading ramp at the speed of the paver, that is to say at a much slower speed (3m / min at 6 m / min) than that of conventional spreaders (30 m / min to 100 m / min); this assembly must generate a low binder flow rate, therefore the orifices of the conventional spreading nozzles are no longer suitable and must have a very small diameter, they tend to become clogged due to the viscosity of the binders used.
  • Document GB-A-1,041,511 teaches a spraying device intended to spread tar or bitumen.
  • This device comprises a spreading ramp provided with projection nozzles, as well as two protective skirts mounted on either side and along the spreading ramp.
  • This device is fitted with a conventional spray system designed so as to be able to accelerate the tar or bitumen, very viscous substances even at more than 100 ° C, through the nozzle orifice to form a liquid film which, possibly, under the effect of the friction of the air, becomes droplets of a size a few millimeters.
  • the spreading of the substance is done by gravity or by the inertia of the droplets which all have an initial speed at the outlet of the nozzle.
  • the present invention therefore aims to overcome these various drawbacks and to provide a spreading ramp device overcoming jets with orifice of very small diameter incompatible with the viscosity of the binders commonly used. It notably proposes a spreading device in which the nozzles are replaced by a chamber containing inside its nebulized emulsion, said chamber being provided facing the road with a large opening, allowing the deposition of said nebulized emulsion on said road.
  • the device proposed by the invention also has the advantage of being compact enough to be able to be placed at the rear of the finisher, behind the tracks thereof, between said tracks and the means of spreading of asphalt mixes on the road.
  • the present invention therefore relates to a device for spreading an emulsion for attaching bituminous mixes on the surface of a road, comprising, on a mobile machine at least one ramp spreading along which the spreading is at least partially carried out, said ramp being associated with an emulsion supply circuit, and comprising at least one chamber comprising at least one opening on its part intended to be opposite the on the road, said chamber being associated with supply and nebulization means making it possible to supply said chamber internally with nebulized emulsion, characterized in that said chamber (19) is also associated with repulsion means, which are located on the interior coating of said chamber, intended to promote the deposition of the nebulized emulsion towards the road through said opening.
  • the repulsion means intended to promote the deposition of the emulsion on the road comprise, in an advantageous embodiment, a coating of the walls, which delimit said chamber, with a material having a low adhesion adhesion to the emulsion or substantially zero.
  • a material constituting said coating can be, for example, of the polytetrafluoroethylene type.
  • said chamber when the bonding emulsion is ionic or electrically charged, said chamber is electrically isolated from the mass of the mobile machine, the walls of said chamber being electrically charged with a polarity identical to that of the 'emulsion.
  • the walls of said chamber may be at least partially made of metallic material, in particular of a stainless metallic material.
  • the walls of the chamber can be positively charged, the emulsion being a cationic emulsion.
  • the chamber is preferably of adjustable length.
  • the chamber may in particular comprise a main part associated with means allowing a lateral extension of said main part.
  • the chamber may comprise a main part extending substantially over a width of the mobile machine and associated at each of its ends with lateral extension means.
  • a room is delimited, in whole or in part, by the walls of a box provided with an opening on its part facing the road.
  • the main part of the chamber is delimited by a central box which extends substantially over a width of the mobile machine and which is associated at each of its ends with a side box connected in leaktight manner by fitting to said central box.
  • the relative nesting length of the central box and a side box being adjustable.
  • the length of the chamber can, for example, be adjusted via hydraulic cylinders.
  • the supply and nebulization means comprise a pneumatic atomizer associated with an emulsion inlet and a pressurized gas inlet.
  • the pressurized gas can be compressed air.
  • the opening of the chamber is surrounded at least partially by flexible skirts extending, in the operating position of the ramp, from said opening to substantially the surface of the road.
  • the room can also be surrounded at least partially by one (or more) curtain (s) of forced air.
  • the chamber can be associated with a gas or hot air supply nozzle.
  • the ramp is preferably associated with means mounted on the mobile machine and allowing the placing in the operating position or the raising of said ramp by compared to the road.
  • Said means for placing in the operating position or for lifting can be hydraulic cylinders.
  • Another object of the invention is a paver construction machine of the finisher type comprising, on a chassis mounted on displacement means, means for spreading bituminous mixes and means for supplying said spreading means, characterized in that it comprises a device for spreading a bonding emulsion of said coated materials on the surface of a road of the type previously described.
  • the device for spreading a bonding emulsion is advantageously arranged at the rear of the chassis with respect to the direction of movement of the machine during the spreading of the mixes.
  • the device for spreading a bonding emulsion can be arranged between the means for moving said machine and the means for spreading bituminous mixes.
  • the device for spreading a bonding emulsion may, for example, be arranged under the part of the supply means which are located at the rear of the chassis, relative to the center of movement of the machine being spreading of asphalt.
  • the feeding means comprise a feeding belt allowing the materials to be conveyed from a zone towards the front part of the machine to a zone towards its rear part
  • said feeding belt can be raised substantially and / or inclined in its rear part just above the spreading means of a bonding emulsion.
  • the machine when the machine comprises a pilot cabin, it also comprises an emulsion tank mounted on the pilot cabin.
  • An interchangeable tank can be mounted on hydraulic cylinders with adjustable height.
  • such a machine may include an emulsion dosing group which includes a metering pump supplying the means of nebulization; it can include a set of controls allowing the enslavement of the flow and the stopping of the supply by linking to the movement and the speed of the machine, this spreading device can be able to be quickly dissociated from the chassis of the machine .
  • the machine can also include a thermally insulated emulsion tank.
  • 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 in its together.
  • 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 s' each extending between a attachment point on the spacer 10 and an attachment point 12 on the side of the tractor frame 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 above the cabin 3 and extends substantially over the entire length thereof. It is mounted on four hydraulic lifting cylinders 14 extending perpendicular to the floor of the cabin 3 in the vicinity of each of the four ends thereof. These jacks 14 allow the height of the tank 13 to be adjusted at will on the finisher 1, said tank 13 admitting, for example, a high position of use and a low storage position facilitating the transport of the finisher 1.
  • This tank 13 is container-cartridge can be replaced during operation, if necessary, the walls of this tank 13 having orifices with valve intended to cooperate with the male ends of pipes 15 and 16, which are supply and return pipes connecting the reservoir 13 to a dosing group 17 of the binder emulsion providing flow and pressure.
  • the reservoir 13 is furthermore a thermally insulated reservoir which can be electrically heated.
  • the device 7 for spreading binder comprises a spreading ramp 18 which essentially consists of a chamber 19 containing inside its emulsion in nebulized form.
  • This chamber 19 is delimited by the walls of a main caisson 20 which is a U-shaped cross section caisson extending along substantially the entire width of the paver 1 and the open part of which faces the roadway C.
  • the chamber 19 is also also delimited laterally by the walls of two secondary boxes 21 and 22 which extend the main box 20 on each of its sides.
  • the two secondary boxes 21 and 22 therefore make it possible, if necessary, to extend said main box 20. They are each associated with a hydraulic cylinder 23 whose cylinder extends respectively over substantially half the width of the main box 20 and whose the movable rod 24 is connected to the secondary boxes 21 or 22 with which said jack is associated by means of a spacer 25 which is secured to them at their end furthest from the main box 20.
  • the box 20 is held on the finisher frame 1 by means of two jacks 26, the rods of which are articulated on the box 20 towards the two ends of the latter and which are mounted on each side of the finisher 1. These two jacks 26 serve as support and lifting cylinders for the spreading ramp 18 relative to the carriageway C.
  • the box 20 is intended to allow the spreading of the emulsion or binder, depending on the width of the finisher 1, the two boxes secondary 21 or 22 to create right and left extensions relative to said main box 20 and to carry out an emulsion spreading on the widths of the finisher 1. In all cases, the spreading is carried out perpendicular to the axis of movement of the machine.
  • Each of the lateral extreme walls of the secondary boxes 21 and 22 is provided with a pneumatic emulsion atomizer 27 to which is connected, on the one hand, an inlet 28 of compressed air and an inlet 29 serving for the supply of binder .
  • These two atomizers 27 create, in the whole of the chamber 19, when they are supplied, an atmosphere supersaturated with nebulized emulsion.
  • the main box 20 is also associated, towards its middle part, with a pipe 30 connected to a hot air circuit and intended for the stripping of the whole of the chamber 19, during the commissioning after stopping of the device d spreading.
  • the box 20 is surrounded externally at its opening by, on each of its sides in its length, a skirt 31 extending in the working position of the spreading ramp 18, from said opening to the floor C.
  • the walls of the boxes 21 and 22 are in turn surrounded internally at the opening of the chamber 19 by skirts 32 also extending from said opening to the floor C, in the working position of the spreading ramp 18.
  • the skirts 31 and 32 are completed by a low pressure air curtain 33 ensuring the elimination of any leaks and surrounding the opening of the chamber 19, the assembly making it possible to delimit in a sealed manner on the pavement C the deposit surface of the nebulized emulsion.
  • the entire device is further supplemented by a high and low pressure air distributor as well as a set of controls.
  • Chamber 19 is associated with means intended to promote the deposition of the nebulized emulsion through its opening on the pavement C. These repulsion means allow a homogeneous distribution of the emulsion nebulized on the pavement C, avoiding, for example, that the emulsion does not amalgamate by plates on the walls of the chamber 19, which plates detaching under the effect of their weight could be at the origin of irregularities on the deposited surface.
  • the aforementioned means can for example be constituted by means making it possible to positively charge the walls of the chamber 19, that is to say the walls of the box 20 and secondary boxes 21 and 22, the emulsion used being a cationic emulsion, boxes 20, 21 and 22 being metal boxes, for example made of stainless steel. Under the effect of electrical repulsion, the particles of the nebulized emulsion, repelled relative to the walls of the chamber, will be precipitated towards the ground, whose potential is grounded.
  • the walls of the box are coated internally with a material of the polytetrafluoroethylene type, whose adhesion to the nebulized emulsion is low or zero and which serves as a means of repulsion.
  • the supersaturation obtained in the box causes the emulsion to run off on the walls of the boxes 20, 21 and 22, then the skirts 31 and 32 ensure the smoothing and distribution of the emulsion on the pavement C.
