Definitions

  • the present invention relates to a process for spreading bitumen and in particular binder; it also relates to the device for implementing the method as well as the machine, of the finisher type for example, capable of including such a device.
  • the creation or repair of pavements by depositing a layer of bituminous mixes using a finisher, requires the prior spreading of a bonding layer.
  • This bonding layer is spread over the surface to be treated by spreading bituminous binder or bitumen emulsion. This spreading is often carried out before the paver passes, using a conventional spreading vehicle; the paver is therefore required to move over the layer of freshly spread binder, like the vehicles responsible for supplying it with bituminous mixes.
  • This spreading device comprises one or more spray nozzles.
  • Each nozzle is mounted on a ramp arranged at the rear of the paver, between the tracks and the asphalt distribution screw. It moves transversely and is animated by a movement which is controlled by the speed and / or the movement of the paver and which is synchronized with its advance.
  • EP-A-292 337 proposes the adaptation of two small ramps behind the tracks of the paver and conventional ramps at the front but carried by a machine which constitutes a kind of extension at the front of the paver.
  • the paver which has its own propulsion means, moves on the surface to be treated, at a speed which is less than 25m / min, generally of the order of 12 to 13m / min.
  • the spreading of the bituminous binder is an operation which is carried out at a speed significantly higher than that of the paver, taking into account the nature of the binder, generally around 30m / min.
  • the binder is a product whose viscosity requires the use of nozzles provided with an appropriate flow orifice. These orifices have an optimized section so as to avoid the risks of blockage.
  • the flow rate of the nozzles is relatively high and, therefore, taking into account the dosages imposed, that is to say given the amount of binder deposited per m2, its spreading takes place at a relatively high speed clearly greater than that encountered for the removal of the asphalt.
  • EP-A-458 667 proposes a dynamic spreading by a back and forth movement of the jet which extends over a relatively large distance.
  • GB-A-1 041 511 also describes a dynamic spreading of the same type.
  • any variation in the movement of the paver will affect the regularity of the spreading and / or the geometry of the emulsion plate deposited by the nozzle.
  • the invention proposes to carry out a spreading which does not depend on the speed of advance of the machine but only on the parameters of the nozzles.
  • These nozzles are preferably conventional nozzles; they have their own operating parameters.
  • the duration of the spreading sequence must be less than the time taken by the machine to cover the spreading step; this duration of the spreading sequence is determined by the number of nozzles arranged on the boom, which number is chosen so as to save a stop time for the nozzles.
  • the invention proposes means which make it possible to carry out a precise spreading of the binder from a machine whose speed of advance on the surface to be treated is relatively low, which speed corresponds in particular to that which one meets on the asphalt laying machines.
  • the invention thus makes it possible to spread bituminous binder, by means of a ramp fitted with conventional nozzles, or nozzles, that is to say nozzles whose flow rate is such that the risks of clogging are nonexistent; this ramp can be installed directly on the paver.
  • the invention mainly proposes means which make it possible to overcome the constraints of the spreading of a bituminous binder and to carry out this spreading whatever the speed or the variations in speed of advance of the machine which deposits the mix; thus the invention makes it possible to guarantee optimal spreading of the binder, from the complete stopping of this machine, up to its maximum speed.
  • the dosage of the binder that is to say the quantity of binder deposited per m2 of surface to be treated, promotes the quality of the bonding of the mix but also the quality of the surface condition of said mix.
  • the invention also makes it possible to promote breakage with the deposition of the mix, that is to say to achieve a natural dissociation of the water-bitumen mixture, by allowing a certain time to elapse between the two operations, namely the spreading operation on the one hand and the asphalt removal operation on the other hand. This feature tends to improve the quality of the bonding of the asphalt layer on the surface to be treated.
  • the invention makes it possible to work on the site in much better conditions, due to the cleanliness of the site, which in particular improves the safety of the personnel and, subsequently, that of the users.
  • the bonding layer is produced by spreading the binder on the surface to be treated at a speed which with respect to the ground is greater than or equal to the speed of advance of said asphalt mixing machine.
  • the invention makes it possible to deposit, step by step, binder, within a precise perimeter, so as to form plates which juxtapose substantially edge to edge to form a layer of binder, continuous and substantially regular in thickness, on the surface to be treated. whatever the machine speed variations.
  • the invention proposes to break down each spreading step or sequence, by performing at least one spreading time, the duration of which is fixed, which is carried out on a forward and / or return movement of the boom and at least one downtime, without spreading, the duration of which is linked to the forward speed of the machine in reverse.
  • This emulsion spreading sequence is triggered automatically each time the finisher has progressed by a distance which corresponds to the spreading pitch achieved by the nozzles.
  • the ramp marks at least one stopping time, the duration of which is related to the speed of advance of the machine; this downtime is preserved by a choice of the number of nozzles arranged on the boom.
  • the spreading device is supported by a mobile machine on the ground and it comprises at least one spreading ramp provided with at least one nozzle forming a binder jet; this device comprises means making it possible to move the jet of binder relative to said machine, at a speed greater than or equal to the speed of advance of this machine, at least during the phase of spreading the binder on the ground.
  • This spreading device comprises at least one slide integral with the machine, making it possible to move the ramp sequentially on said slide, or means making it possible to oscillate the nozzles to sweep the surface to be treated with the jets of binder.
  • this spreading device comprises means for determining the path traveled by the machine on the ground, means for triggering a spreading sequence which comprises: - the sweeping back and forth movements, and - the or downtime.
  • the spreading device comprises, for maneuvering the boom, two opposite cylinders, of the single-acting type, supplied through a distributor of the crossed type, which cylinders each have an orifice allowing, at the end stroke, a free escape of the operating fluid during the stop time of the ramp.
  • the invention also relates to the machine and in particular the paver allowing the production or repair of pavements, of the type comprising, at the front, a hopper for receiving asphalt, and, at the rear, a table for distributing these coated on the ground, and a binder spreading device which makes it possible to spread the latter on the surface to be treated intermittently, at a speed greater than or equal to the maximum speed of advance of the paver, associated with means which used to trigger a spreading sequence during which said ramp observes a downtime.
  • the paver allowing the production or repair of pavements, of the type comprising, at the front, a hopper for receiving asphalt, and, at the rear, a table for distributing these coated on the ground, and a binder spreading device which makes it possible to spread the latter on the surface to be treated intermittently, at a speed greater than or equal to the maximum speed of advance of the paver, associated with means which used to trigger a spreading sequence during which said ramp observes a downtime.
  • Figure 1 schematically, a machine of the finisher type allowing the application on the floor of a layer of bituminous coated material type.
  • This paver has a track-like undercarriage 1 or wheels, which in particular supports a hopper 2 at the front, and it includes, at the rear of the tracks, a table 3 used for the distribution of the material on the surface. treat.
  • a bonding layer is spread out beforehand by means of a ramp 4 arranged transversely on the machine.
  • the spreading ramp 4 is located behind the tracks 1 to avoid the latter to roll over the freshly deposited bonding layer.
  • the ramp 4 b can be placed at the front of the finisher. This arrangement improves accessibility to the boom for maintenance operations and has the advantage of allowing a certain time to elapse between the two operations, namely the spreading operation on the one hand, and the operation on the other hand.
  • FIGS. 2a and 2b have illustrated some possibilities for positioning the ramp 4 on the finisher.
  • a ramp 4 a which extends to the rear caterpillars 1 over the entire width of the finisher. It is also possible to use, depending on the space available on the finisher, several portions of ramps as shown in FIG. 2a.
  • a section 41 at the front of the finisher which covers the space between the tracks 1.
  • This ramp 41 can be arranged in front of the tracks 1, under the hopper 2 for example.
  • the rolling area of the tracks 1 is covered either by a short section 42, or by a wider section 43, which extends beyond the size of the tracks.
  • the part located outside the tracks 1 can also be covered by a section 44 which completes the action of the section 42.
  • These different sections 41 to 44 carry out the spreading of a layer corresponding to the width of the distribution table 3. These different sections are positioned so as to avoid rolling of the tracks 1 on the bonding layer.
  • FIG. 2b shows a ramp 45, of the telescopic type by means of two lateral portions 46, which is located at the front of the finisher, under the hopper 2.
  • this ramp at the front will be used.
  • the risks of slipping and fouling of the tracks require the use of nozzles 47 arranged at the rear of the tracks of the finisher. These nozzles 47 will replace the corresponding nozzles of the ramp 45 located at the front.
  • the ramps 4 a and 4 b are equipped with conventional nozzles comprising sprinklers whose sections allow flow rates of the order of 3 to 9 liters per minute, which avoids the risk of clogging.
  • FIG. 3 shows a simple diagram functional, a spreading device arranged transversely to the direction of advance of the carrier machine which makes it possible to produce longitudinal strips 6 of binder, arranged edge to edge to form the bonding layer.
  • Each strip 6 has a width which corresponds to the distance between two nozzles 7 of the ramp 4 and it consists of a plurality of plates 8 juxtaposed and arranged edge to edge on the surface to be covered.
  • These plates 8 have a shape which depends on the speed of advance. Their shape is most often almost rectangular; it looks like a parallelogram when the ratio between the speed of spreading of the binder and that of the removal of the asphalt decreases. When the speed of the machine varies between two scans, there may be a slight overlap of the plates 8.
  • the length of the plates corresponds to the width of the strips 6 and their width corresponds to the width of the jet 9 of the nozzles 7.
  • the ramp 4 is guided by appropriate means on a slide 10 which is integral with the frame 11 of the finishing machine.
  • This slide 10 is arranged transversely to the direction of advance of the machine. It can consist of several sections which are then arranged, as for the ramps shown in FIGS. 2a and 2b, either at the front of the machine, or laterally with respect to the tracks 1, or at the rear of the tracks 1.
  • the ramp 4 is movable on this slide 10 by means of a jack 12 secured to the frame 11 and which is actuated by a distributor 13 by means of a hydraulic or pneumatic supply for example.
  • the stroke C of the jack 12 corresponds to the spacing between two nozzles 7 of the ramp 4. It also corresponds to the width of a strip 6 of binder.
  • This jack 12 is controlled, through the distributor 13, by means of a sensor-like member 14, which triggers a spreading sequence as a function of information given for example by a wheel 15, in contact with the ground.
  • This wheel 15 is a coded wheel, by appropriate means, of the nipple or hole type which cooperates with the member. detector 14 so as to trigger a spreading sequence when the finishing machine has advanced by a distance which corresponds to the pitch P of the spreading.
  • This pitch P of the spreading corresponds to the width of the jet 9 or bundle of binder projected by the nozzles 7, on the ground.
  • Each strip 6 of binder consists of a juxtaposition of plates 8 whose dimensions correspond to the stroke C of the jack 12 and to the pitch P of the spreading, that is to say to the imprint of the beam of the nozzle 7, on the ground.
  • the nozzles 7 spread the binder within a very precise perimeter by means of a sweep of the surface to be treated.
  • the binder layer is obtained by a transverse scanning movement; it can be obtained by a longitudinal scanning movement. This scanning is itself obtained either by a global movement of the nozzle carrying ramp 7, or by an oscillation movement of the nozzles around transverse or longitudinal axes.
  • the nozzles 7 are oriented accordingly to position the jet 9 in a direction perpendicular to the direction of movement or oscillation of the nozzle.
  • a longitudinal sweep that is to say a sweep in the same direction as the advancement of the machine, the variations in the advancement speed of said machine will not cause overlapping phenomena of two successive plates 8, as may possibly be observed in the case of a transverse scan.

  • the diagram shows the transverse stroke C of a nozzle 7 and its longitudinal displacement D.
  • the nozzle travels a forward path A which corresponds to the stroke C of the jack 12, then it performs a return R of the same elongation which reposition it at its starting point.
  • the outward and return journey of the nozzle takes place in a time which is less than the time necessary for the machine to cover the pitch P of the spreading.
  • the ramp 4 remains in the rest position while the machine continues to advance, waiting for the start of another spreading sequence.
  • This rest period S makes it possible to absorb any variations in speed of the finishing machine. If the time required for a nozzle to go back and forth becomes greater than the time taken by the machine to cover the spreading step, it suffices to multiply the number of nozzles to reduce the time spent in a sequence by as much, during spreading, and maintain a sufficient rest period S between two spreading sequences.
  • This spreading is generally carried out in a single layer during the outward journey A of the nozzle.
  • FIG. 5 shows, by means of a functional diagram, a spreading device which takes up the essential characteristics of the device represented in FIG. 3.
  • the surface which is to receive the coating layer, is covered with binder and in particular with plates 8 as described in relation to FIG. 3.
  • the spreading device comprises two jacks 21 and 22 arranged back to back, to maneuver the boom 4.
  • These jacks 21 and 22 are of the single effect type : the jack 21 pulls the ramp to move it from left to right, as shown in Figure 5; the jack 22 pulls on the ramp 4 to move it from right to left.
  • These two cylinders have the same stroke C which corresponds to the distance between two nozzles 7.
  • These jacks 21 and 22 each comprise a supply 211-221 which is located at the level of the passage face of the rod of each of them. At the other end of the body of these jacks, there are respectively the exhaust orifices 212 and 222, located upstream of the piston when the latter reaches the end of the stroke. There is thus obtained end-of-travel damping and a pressure drop in the hydraulic supply circuit without prejudice to operation. This feature provides a free escape of the operating fluid during the ramp down times at each end of travel.
  • the jacks 21 and 22 are integral with the frame 11 of the machine. They are positioned in opposition, as shown in FIG. 5.
  • the volume of their chamber can be different to allow a variation in the speed of movement of the ramp 4 on the outward and return as the feed rate is constant .
  • This possibility of varying the speed of the ramp on the outward and return journey makes it possible to carry out different dosages depending on whether the nozzles are used on the outward or return journey.
  • the use of the outward and return for spreading allows a dosage of 750g / m2.
  • This variation of the dosage can thus be carried out simply by a choice of the spreading period by means of a simple selector, without changing anything at the installation.
  • the two jacks 21 and 22 are actuated under the effect of a distributor 23 of the crossed type comprising an electromagnet which allows the displacement of the drawer in one direction, and a return spring of the drawer.
  • This distributor 23 receives an order to operate one of the jacks; deleting this order automatically operates the other cylinder.
  • the distributor 23 is subject to the orders of a counter programmable electronics 24 which receives the pulses from a generator 25 driven by any suitable means, the movement of which is proportional to the speed of advance of the machine.
  • this generator 25 is mounted at the end of a drive shaft for the tracks 1 of the machine; it determines its advance on the surface to be treated, and the distance traveled.
  • the cylinders 21 and 22 are supplied by a pump 26 drawing from a reservoir 27.

  • These nozzles 7 carry out rounds A and return R interspersed with exposure time SA , SR .
  • the electronic counter 24 sends pulses intended for the distributor 23, to activate one of the jacks 21 or 22; the duration of these pulses corresponds to half the time necessary to travel a distance P which corresponds to the width on the ground of the jets 9, according to the example of FIGS. 5 and 3a.
  • the supply pressure is practically zero, due to the free escape of the hydraulic fluid through the orifice 212.
