Definitions
- the present invention relates to a stabilized structure comprising separate individual mineral elements and a process for stabilizing such a structure using a complex stabilization.
- Structures with mineral elements are known in various fields such as, for example, railway construction and road construction.
- mineral or stony elements for example pebbles from crushed rocks magmatic and some metamorphic rocks.
- These stony elements can in particular be arranged so as to forming a bed of stones intended to constitute the ballast of a track railroad or a base layer in road construction.
- They may be small stones, susceptible to land on the running table of the rails, and thus be crushed by the wheels, causing fingerprints.
- a solution to prevent the lifting of stones forming the ballast of a railway is proposed by the document WO-A-9108056.
- a multi-component resin is used that we spread on the ballast to get a partial covering of the stones forming the ballast.
- the characteristics of the binder are chosen so that it coats the stones from the ballast partially and over a shallow depth of the ballast, so that the upper stones are attached to each other to others without compromising the drainability of the ballast.
- the object of the invention is to find a solution allowing to remedy the drawbacks of structures comprising stony elements of different sizes, simply, little expensive and fast and, at the same time, retaining the properties essentials of the ballasted structure, such as, for example its ability to distribute loads, its ability to drain and rapid drainage.
- the structure comprises a complex of stabilization consisting of an added complex comprising a binder and fibers, and ensuring the maintenance elements of the structure.
- the mineral elements of surface are partially coated by the reported complex, which ensures a link between them and their immobilization one by compared to others, without affecting their ability to drain and percolation.
- Patent protection does not extend to modes of realization of the structure according to Figures 3 and 4.
- the channels for railways are made up of rails fixed on sleepers, themselves immobilized on a ballast 1 composed of stony elements, such as pebbles 2, from rock crushing magmatic or metamorphic, and arranged between the rails and on either side of these.
- ballast 1 has a complex stabilization 3 consisting of an attached coating which forms a sort of covering net for said pebbles 2 of the layers without affecting their drainage and percolation.
- This covering net ensures a connection between the pebbles and, consequently, their immobilization in relation to to others.
- the stabilization complex 3 of the ballast 1 is constituted by a binder 4 to which fibers 5 are incorporated.
- the binder 4 can be a pure or modified bitumen emulsion or an anhydrous binder.
- the fibers 5 integrated into the binder 4 to form the stabilization complex 3 intended to be attached to ballast 1 are filiform and of length l at least equal to the distance separating two successive stones 2, to form a link between them. All of these links, obtained from stabilization means comprising fibers 51 hereinafter called “long fibers” and binder 4, is arranged randomly and according to a dosage making it possible to carry out a any shape mesh capable of joining the pebbles of surface 2 between them, while allowing the drainage of water from rain through the top layer of pebbles 2, then their lower layers.
- ballast 1 has a complex of stabilization 31 which is constituted by a binder 4 in which are integrated fibers 52 hereinafter called "short fibers".
- the length m short fibers 52 and the dosage of these fibers during their application are chosen so as to obtain a random blockage part of the gaps between the stones.
- the binder is retained during its application and forms a mesh of any shape similar to the first embodiment.
- the long fibers 51 may have a length l ranging from 10 mm to 200 mm
- the short fibers 52 have a length m less than 1 mm and are in particular micronized fibers.
- the preferred lengths of long fibers 51 are 25, 50, 90 and 130 mm, the particularly advantageous length being located between 25 and 60 mm.
- the life cycle of the maintenance-free ballast can go up to three or even five years, whereas with ballasts traditional, this life cycle does not exceed one year in the most severe conditions of use, for example those of high speed lines.
- the stabilization coating has the ability to be easily destroyed during manual tamping operations or ballast mechanics, which keeps the ballast its recyclable material.
- the stabilization coating also allows maintain a ballasted layer behavior capable of withstand the vibrations in the passage of train movements. he remains flexible enough to follow the deformations of the support and accept a low amplitude sag.
- the stabilization complex 3 of the ballast 1 comprises, for example, an emulsion of pure or modified bitumen whose dosage is between 1500 and 1800 g / m 2 or an anhydrous binder whose the dosage is between 800 and 1200 g / m 2 , and to which emulsion or to which anhydrous binder, long fibers 51 are incorporated, the dosage of which is between 50 and 600 g / m 2 .
- a hydrocarbon binder based on bitumen
- suitable additives for example: SBS type polymers
- This type of binder obtained for example by addition or not 1.5 to 3% SBS polymer in a penetrating bitumen given has a viscosity depending on the temperature at the time of spreading.
- Full-scale experiments have shown that a viscosity obtained by spreading the binder defined above to a temperature between 40 ° C and 90 ° C allowed bonding ballast per point on the surface and penetration over a thickness from 1 to 3 ballast stones.
- the temperature drops in a time between 0 s and 600 s at a value ⁇ 25 ° C, which allows point bonding of the ballast, irreversible at room temperature, sufficient for prevent pebbles from flying away when trains pass, but weak enough for a powerful mechanical action by vibration for example, allows to restore independence mechanics of each pebble and therefore to rework the geometry of track by ballast stuffing.
- the tensile stress required to separate two pebbles from the ballast thus glued is between 50 g / cm 2 and 2000 g / cm 2 at 30 minutes, which is more than enough not to interfere tamping operations.
- the invention also relates to a method using works a stabilization complex to obtain a structure such that it has just been described.
- This process includes a step consisting in forming a kind of partial covering net for mineral elements of the upper layers of the structure to stabilize.
- very long fibers 51 are cut in situ by through a chopper type fiber cutter a rotating cylinder fitted with peripheral chopping blades, fed by a loading hopper, such a cutter being associated with a bitumen spreader 4 arranged upstream or downstream of said cutter, on the same running gear.
- precut fibers are brought to the site to be put implemented before or after the spreading of the bitumen 4, by spraying with a manually operated spray gun or mechanically.
- the process can be carried out in the temperature range from + 5 ° C to + 40 ° C. Treatment can be carried out on a ballast wet using a bitumen emulsion binder. The effectiveness of process is obtained whatever the climatic conditions after implementation within a maximum of 24 hours.
- the invention has been presented as relating to a structure stabilized with individual mineral elements, separate, comprising a stabilization complex consisting of a complex reported that partially covers the mineral elements of surface of this structure and which comprises a binder and fibers.
- the stabilization complex consists of a binder alone or, for the least, by an added stabilization complex not comprising no fibers.
- This principle is represented schematically in Figure 4. In this Figure, we see that the elements of upper layers of the structure to be stabilized are "glued" one
- the detailed illustrative description relates to the stabilization of a railway ballast type structure. It must be understood, however, that the invention is not limited to such an application and can be used to stabilize any structure stony comprising stony elements. The skilled person can, through routine testing and using the lessons of the present description, determine in each case according to the nature and dimensions of the structure to be stabilized, corresponding characteristics of the binder and of the fibers.
- a reservoir structure roadway includes, in addition to the ground support 11 on which it is made, a form layer 12, a foundation layer 13, a base layer 14 and a layer surface 15.
- the support soil 11, the form layer, the layer foundation and the base layer are separated from each other by interfaces 16, 17 and 18 produced by a geotextile or a geomembrane.
- Stabilization complex 3 is applied to the layers base of mineral elements of the base layer 14.
- the Figure 5 shows this complex according to the embodiment shown in and described with reference to Figure 3.
- the stabilized structure can be used in the field of road application using dusting microfibers. These microfibers are only in organic matter and applied, either with pistols or with a ramp. Their main effect is to avoid any object or vehicle entering contact with the newly deposited stabilization complex, paste.
