Definitions
- the invention relates to a method for the solidification of pourable materials, e.g. Ballast, grit and / or slag, manufactured structures, in particular covers of ballastless railway superstructure, the so-called "slab track", or of ballast piles of the classic superstructure, using a thermoplastic bitumen-based binder.
- pourable materials e.g. Ballast, grit and / or slag
- crushed stone, grit, slag and similar such materials in railway construction, hydraulic engineering, road construction and other areas of the building industry as a grain heap in both unbound form, i.e. without the addition of hydraulic binders or binders made of, for example, plastic or bituminous as well to be used in bound form, ie with the addition of such binders.
- ballast pile of the railway superstructure namely the ballast superstructure. This secures the track grate in its position, distributes the wheel loads over the rails, sleepers and the ballast bed in such a way that they are borne permanently and without damage by the substructure, absorbs the loads in a springy or damping manner and reduces noise radiation.
- the threshold fields are filled with bulk materials of suitable grain sizes.
- Such a fine-grained material can, however, be whirled up by the suction force, which is primarily caused by fast-moving passenger trains, ie individual grains of gravel are torn out of their position by the suction and flung up.
- Such gravel swirls can be caused in particular by cold ice in the cold season, when in winter ice loosens from the vehicle floors and hits the gravel surface at high speed.
- Even coarse-grained ballast 25/65 can still be torn out of its position and flung up.
- the object of the invention is now to improve a method of the type mentioned in such a way that the ballast material is brought into a state suitable for later consolidation even before installation, and the material treated with binders is stored for several weeks without gluing and afterwards is still transportable and the desired consolidation is ensured after installation in the road.
- the material is processed in a suitable plant and coated with a film of a thermoplastic binder that is as thick as possible, the coated material is converted into a non-adhesive state by means of a suitable medium and, if appropriate, with the addition of suitable release agents, and the material treated in this way is brought into the building and is thermally treated during and / or after installation.
- the rock and / or slag material treated according to the process described above has the advantage over the known processes described at the outset that there is no premature bonding in the rock material during intermediate storage and transport to the installation site, in particular it can be stored for several weeks without bonding.
- the binder is hot bitumen and the material is heated in an asphalt processing plant of known design, dusted and coated with a thickest possible film of hot bitumen and then the coated material with a cooling medium, e.g. Air or water may be extinguished with the addition of suitable release agents.
- a cooling medium e.g. Air or water may be extinguished with the addition of suitable release agents.
- the built-in material is advantageously heat treated during and / or after installation with hot air devices or infrared radiators.
- cellulose and / or mineral fibers are added to the binder during the coating process. This ensures in particular that the binder coating is given the desired thickness.
- Chemical additives can advantageously be added to the binder. Such additives reduce the flow properties of the binder and in particular prevent dripping when hot.
- the method according to the invention described above can also be used especially in the case of classic ballast track superstructure, that is to say without a solid roadway.
- One from the procedural The track superstructure made of treated ballast can be replanted without further ado, the material surrounded by the thick binder film also guarantees re-gluing.
- the method described above can be used not only in railway construction, but also in hydraulic engineering in the manufacture of bank reinforcements, filter layers and asphalt seals etc.
- the additional application of hot asphalt surfaces also leads immediately to the desired bond.
- the method according to the invention can also be used when installing such materials as stable protective and filter layers on heat-sensitive sealing foils.
