Definitions

  • the invention relates to a device for spreading liquid binder and gravel at the back of a road construction machine.
  • a spreading train consisting of a bitumen spreader and of a gravel maker.
  • the spreader should spread the binder, which is either a emulsion or hot bitumen, on the pavement with very high precision and perfect regularity in the transverse direction of the surface road and spreading train.
  • a multiple-jet ramp that is to say a ramp comprising nozzles distributed in the longitudinal direction of the arranged boom in the transverse directions of the road surface, with one step of constant spacing, for example a pitch of about 100 mm.
  • the ramp is supplied with liquid binder and the nozzles are produced so as to produce a conical jet having an elongated section in the transverse direction and similar to a triangular flat jet which meets the road surface, along an impact surface whose length, in the transverse direction, depends on the angle at the top of the flat spray and the height of the ramp above of the road surface.
  • a ramp height, above of the road surface depending on the angle at the top of the flat jets and the no nozzles on the boom, such as the impact surface of each of the jets has a length of about three steps in the transverse direction.
  • three jets are superimposed, which gives three road surface coverings.
  • the gravel is generally deposited on the liquid binder covering the road surface, by a gravel spreader comprising a plurality of successive hatches of constant width, distributed along the direction transverse of the road surface and ordered for their opening or closing, so as to adjust the spreading width of gravel on the road surface covered with liquid binder.
  • a gravel spreader comprising a plurality of successive hatches of constant width, distributed along the direction transverse of the road surface and ordered for their opening or closing, so as to adjust the spreading width of gravel on the road surface covered with liquid binder.
  • the gravel spreader multi-trap is fixed on the bottom of the tipper of a dump truck in which we load the gravel. A good transverse distribution is thus obtained.
  • Such work may relate to isolated more or less circular zones or bands of a smaller width to the width of the road surface.
  • a method manual consisting of applying the bitumen with a hand lance and spread the gravel using a gravel container. This rudimentary technique is used less and less, and we prefer to use materials allowing point work to be performed on time, automatically.
  • the materials used are machines which bring together on the same road vehicle a small spreader and a small gravel bucket associated to a gravel maker.
  • a more annoying drawback of this technique is that it leads to poor quality surface coatings because it no longer meets the principle implemented in the spreading trains which consists in depositing bitumen on the road surface with three overlaps.
  • To make repair work on small areas place the ramp bitumen spreading at a height above the road surface which is less than the height usually used on spreading trains.
  • each of the jets forms an impact surface whose dimension in the transverse direction is only two steps and the overlap jets produces only two overlaps, by superposition of two jets on each step of the impact surface.
  • the object of the invention is therefore to propose a device for spreading liquid binder and gravel at the rear of a road vehicle comprising at least a binder spreading ramp fixed to a rear part of the road vehicle, in a transverse direction, and having a first set of nozzles spreading agent spread along the length of the boom in the direction transverse with a constant spacing pitch, directed towards a surface road on which the road vehicle moves and adjustable means supply of the ramp by tying, so as to supply all or part of the nozzles of the first set to form at the outlet of each of the nozzles a flat jet having an angle at the top such that depending on the height of the ramp above the road surface, each jet has an impact surface on the road surface about three steps wide in the direction transverse and that the jets of the first set of nozzles overlap so that, for each of the successive steps of the impact surfaces of the jets, in the transverse direction, three jets overlap, and one gravel spreader attached to the rear of the road vehicle, in a transverse arrangement in opposite the binder spreading ramp, for spreading

  • the central part 14a of the treated area is of a quality average and inferior to the quality of a wide width coating, due to it only has two bitumen coverings.
  • the lateral parts 14c and 14d which only have an overlap bitumen cannot ensure sufficient adhesion of gravel which are easily torn off and the overflow zones 14'a and 14'b, at outside the gravel area, there are bitumen drips which are detrimental to the quality of the pavement and are not used to ensure adhesion of gravel.
  • the ramp 6 of the device according to the invention comprises a first set of nozzles 7a arranged with a constant spacing step P which can be for example 100 mm and therefore equal to the spacing pitch of the nozzles of the ramp 6 according to the prior art described above and a second set of nozzles 7b arranged each, in the transverse direction, between two nozzles 7a of the first set of nozzles.

  • the ramp is placed at a height H which is the usual ramp height in the case the production of wide road surfaces for maintenance roads. This height is generally 50% higher than the height of ramp h used in the case of point-to-time work with machines automatic.
  • the two nozzles 7b of the second assembly located towards the outside and of on either side of the set of four nozzles supplied 7a of the first all are supplied with bitumen at a flow rate substantially equal to the flow rate supply nozzles 7a and are made so that the jets 15 formed by these triangular flat shaped nozzles and having an apex angle ⁇ intersect the road surface 10 along an impact zone with a width two steps in the transverse directions, taking into account the height H of the ramp 6.

  • the invention has been described in the case where a repair is carried out on a strip with a width equal to two widths of spreading gravel or still six steps apart from the nozzles of the first set of the boom. It is possible to carry out repairs on tapes which have general, a width equal to an integer multiple equal to two or more the spreading width of a gravel trap.

  • the device is in particular well suited to the classic case of repair on strips of width 600 mm. In this case, in addition to the quality advantages of the repair strip, economic advantages are obtained substantial by avoiding wasting the bituminous binder and the gravel. For works 600 mm wide, we were able to show that we were saving up to 16% binder and 16% gravel.
