Definitions

  • the road surface material essentially consists of bitumen or asphalt and grit of different grain sizes.
  • Coarse grit grit is used to build a support structure, grit of smaller grit fills the cavities of the support structure within limits and the bitumen or asphalt penetrating the prepared road surface connects the grit components with one another and fixes them in their position.
  • the individual road surface components are used in the correct mixing ratio. This is particularly important if the individual components are not applied one after the other in the ceiling area, i.e. first the support structure is built up from coarse grit, then smaller grit size is caused to penetrate into the cavities of the support structure and the bitumen or asphalt is finally applied, but if the pavement mix is first prepared separately and then applied as a whole to the pavement substructure. Such methods are used, in particular, for reasons of the most efficient possible way of working.
  • the individual components are brought together in mixers and mixed well, then brought to the processing temperature to be finally processed, i.e. to be applied to the road base.
  • the chippings of different grain sizes are placed on a conveyor belt in the correct mixing ratio from a number of feed hoppers corresponding to the number of different chippings and introduced into a lying drum which rotates about its longitudinal axis.
  • the grit is introduced into the drum at one end and conveyed to the other end of the drum while the drum is rotating. From this other end of the drum, a burner protrudes into the drum, the direction of the flame of which is opposite to the transport direction of the material and heats it to about 200 ° C.
  • dust and moisture are removed, so that at the end of the drum grit leaves, which is dried, preheated and freed from dust.
  • the chippings in the desired grain composition leaving the drum in such a processed state are introduced by means of a bucket elevator into a classifying device with a balance, in which a suitable proportion of the previously removed dust is added to the chippings, as well as bitumen and a filler in a predetermined amount.
  • a suitable proportion of the previously removed dust is added to the chippings, as well as bitumen and a filler in a predetermined amount.
  • bitumen at a temperature of 165 ° C
  • the filler at a temperature ⁇ on 10 ° C is added.
  • the mixture with those guaranteed by the balance Constant mixture proportions are finally mixed well in a twin-shaft compulsory mixer and are available for processing, ie for application to the pavement substructure.
  • the system described above was modified in such a way that the drum is concentrically surrounded by a sieve drum, which consists of sieve sections of different mesh sizes which follow one another in the longitudinal direction of the drum. After the chippings of different grain sizes have emerged at the discharge end of the inner drum, the chippings enter the annular space between the inner drum with the drum casing closed up to the outlet openings and the sieve drum. For its part, the sieve drum is surrounded by a housing which has a discharge funnel at the lower end. The grit is classified by the sieve drum and passed through the discharge hopper for further processing. The further processing takes place as for the system described above.
  • This system also achieves a usable result, the constructional and operational effort is reduced, but it is also not possible to reuse the material of old road surfaces with this system.
  • the object of the present invention is to improve the known system in its two versions in such a way that the structural and operational expenditure is further reduced and that in particular the reuse of old road surfaces is possible.
  • a drum 2 In a fixed housing 1 there is a drum 2 with a horizontal longitudinal axis 3 rotatably supported about this longitudinal axis.
  • a burner 4 whose longitudinal flame axis coincides with the longitudinal drum axis 3, projects into the drum 2 from the left drum end in the illustration.
  • the burner can be of any type and can be operated with gas or oil.
  • the drum 2 is driven by a motor (not shown) via a gear unit which includes a race 5 surrounding the drum and firmly connected to it.
  • a plurality of so-called hot silos 6 are arranged one after the other in the longitudinal direction of the drum on the housing 1.
  • These hot silos are funnel-shaped containers that are largely insulated from temperature radiation and that contain the chippings of different particle sizes that emerge from the drum 1, mixed with bitumen or asphalt in a manner to be described below, and place them on a conveyor belt for further processing.
  • circular screens 7 are arranged in succession in the longitudinal direction of the drum on the drum 2 such that an annular space 8 exists between the jacket of the drum 2 and the circular screens 7.
  • the circular sieves have different mesh sizes, the circular sieve 7a with the largest mesh size being on the right in the drawing, the circular sieve 7d with the smallest mesh size being on the left end of the drum 2 in the drawing.
  • the annular space 8 communicates with the interior of the drum 2 via openings 9 which are evenly distributed over the drum circumference at the drum end on the left in the drawing.
  • a mixture between the old asphalt introduced via the device 11 and the fresh material introduced via the device 10 takes place in the area of the discharge openings 9, the old asphalt is less directly through the burner 4 than indirectly through the guidance of the scraper through the flame zone and through Heat absorption from the fresh goods warmed. a Ignition of the asphalt is largely impossible.
  • the old asphalt is in the mixing drum for a relatively short time, is heated without direct contact with the flame, and is mixed well with the chippings coming from the other end of the drum during the heating process.
  • the mixture of old asphalt and grit passes through the openings 9 into the annular space 8 and from there, classified according to the size of the grit, into the hot silos 6 and can be removed for further processing.
  • the dust and moisture are discharged through an exhaust stack 19 at the drum end of the feed device 10.
