Definitions

  • the present invention concerns a automatic asphalt paver machine for roads and other paved areas.
  • This solution consists in applying an anchorage tack coating on the road surface (bitumen emulsion and water) before lying the asphalt carpet to perform a best sticking.
  • Finishing machines are well known to depose on the road surface new asphalt layers, these self-movable machines or movable system crawler, involve in adjustable order in rearward height asphalt distribution cochlea means, followed by rolling compacting means having a minimum width to which rearward are associated movable sideways roller compacting means having the further function to widen and compact the asphalt on a larger extension on the road if compared of the width of the paver machine.
  • cochlea means are symmetrically transversely laterally extendible to distribute and to stretch the asphalt according as per a greater width to the minimum width of the machine to satisfy the exigencies of a side speread by means of said enlargeable compacting means.
  • Scope of the present invention is to allow the machine to explicate a more wide operation activity that can include the method above-mentioned or different, having the possibility to utilize said means for other scopes as said to spray or jet a fluid on a road paving before of said carpet distribution enlarging and compacting means In order to make possible to operate the spray-jet means at different advancing speed with constant superficial treatment and with different asphalt carpet width distribution.
  • said spray-jet means are enlargeable by means of at least two spray sets transversely disposed and operatively downwards oriented mounted on displacement cross means, to move from a reunited substantially central position to a position substantially more or less externally enlarged in opposition in order to cover different road width surface in conformity at least to the prearranged width in said asphalt carpet enlargeable distribution means.
  • the Figures disclose that the invention regards a self-propelled or towed paver finishing-machine involving rearward adjustable means in enlargeable height (B), for the distribution in uniform way of at least one stratum of asphalt or similar bituminous concrete and its compacting, involving upwards of said asphalt layer enlargeable distribution and compacting means (B), spray means or jet means to spray fluids substances on the road surface (A), these means being adjustable in height by dynamic-fluid (cylinder) independent device (7).
  • B rearward adjustable means in enlargeable height
  • B for the distribution in uniform way of at least one stratum of asphalt or similar bituminous concrete and its compacting, involving upwards of said asphalt layer enlargeable distribution and compacting means (B), spray means or jet means to spray fluids substances on the road surface (A), these means being adjustable in height by dynamic-fluid (cylinder) independent device (7).
  • Said spray means of fluids substances include at least two sprayer sets (1,1') transversely disposed with downwards oriented nozzles mounted on displaceable means, to be transversely extended on opposed side from a reunited substantially central position (Fig.3) to a substantially side extended more or less wider position (Fig.4) in order to cover a different width of road surface in conformity at least of the prearranged width in said asphalt carpet enlargeable distribution finishing compacting means (B).
  • Advantageously said sprayers means are transversely extendable to form a continuous crossing spray lines.
  • said sprayers means (1,1') are alternatively transversely movable.
  • said spray means for the fluid road coating or wetting include also a central device with alternatively transversely movable sprayer means (2).
  • Said spray central device is orientated to extend the spray at least longitudinally.
  • the spray flow is varied in function of the speed of advancement varying correspondingly the delivery pressure.
  • the sprayer device is also adjustable in height.
  • Figures 6 and 7 disclose that with V1 speed of advancement we have for example, with a pressure p1, a spray angle ;8, consequently in order to obtain a spray amplitude "D" on the road surface, we distance the sprayer at a height H from the road surface in proportion.
  • the oscillation frequency of the oscillation device is variable in direct proportion to the variation of the advancing speed.
  • Said asphalt layer enlargeable distribution and compacting means (B) are adjustable in height by means of lateral arms (6) ) and involve asphalt bidirectional distribution coclea means (clockwise-counterclockwise) acting as divaricators (3) transversely extendable in opposition (3') and rearward are disposed asphalt layer roller compacting means (vibrators, rolls Etc), involving central compacting means of minimum fixed width (4) to compact a restricted central band road area surface and rear, two transversely movable in opposition compacting means to enlarge and compact the carpet in the opposed sides in larger with then the width of the machine (5).
  • the machine includes furthermore to assist the spray system:
