Abstract

Road bed structure of the type which consists of a foundation (2), provided on a soil track (1), and a laying bed (4) for small-scaled elements (5), characterized in that between the upper side of the foundation (2), which is arranged with an inclination, and the laying bed (4), means are provided which guarantee for the draining of water which seeps between the joints of the small-scaled elements (5) towards the foundation (2).

Description

  • The present invention relates to a road bed structure, more particularly a road, the top layer of which is composed of small-scaled elements which are provided in a laying bed.
  • It is known that up to the present, roads substantially are formed by providing, on a soil track, a foundation with a thickness of 15 to 25 cm, depending on the subsoil and the road's load to be expected, by subsequently providing on this foundation a laying bed consisting of sand, sand cement, a mixture of sand originating from a crushing installation and gravel, a ternary sand mixture or mortar, whereby the thickness of this laying bed is maximum 3 cm and whereby the small-scaled elements are provided on this laying bed.
  • With these known road embodiments using small-scale elements, local settlements occur in the surface finishing, as a result of which, amongst others, the formation of puddles will occur, with all consequences thereof.
  • Indeed, with these embodiments, when it is raining, water will be collected between said foundation and the upper side of the small-scale elements, as a result of which at these places, so to speak, a water tub is formed.
  • In consideration of the fact that there is only a limited surface draining possibility for the rain water, water will flow between the joints of the small-scale elements towards the subconstruction of the road bed structure.
  • As a consequence, a saponification effect is created, by which, on one hand, the joint filler is sucked away from in between the small-scaled elements, due to the vacuum effect created by the tires of the vehicles driving thereover, and, on the other hand, the laying bed, in a more or less liquid form, is pushed upward through said joints, which happens under the influence of the wheels of the traffic which exerts a considerable vertical and horizontal pressure onto said small-scale elements, as a result of which permanent deformations of the top layer of the road bed structure are created.
  • The present invention aims at excluding the aforementioned and other disadvantages and provides for a road bed structure whereby the rain water, which normally penetrates up into the lowermost part of the road bed structure, is drained in a suitable manner.
  • By thus draining the rain water in an accelerated manner, the surface water also is less affected by the pollution of the road traffic, as the rain water no longer stagnates in the polluted environment of the road bed structure and therefore less hydrocarbons, de-icing salts and such, in their turn end up in the surface waters.
  • To this end, the road bed structure not only will be realized with an inclination of approximately 2 %, however, also a drainage will be provided between said actual foundation of the road bed structure and said laying bed, such that the agglomeration of water above said foundation is avoided at all times.
  • Said drainage will be formed by a water-permeable material, which material comprises passages.
  • This drainage preferably will be formed by a foil which is provided with ribs, nubs or the like at its underside, in order to form tiny draining channels above said foundation, through which the rain water can be drained.
  • With the intention of better showing the characteristics of the invention, hereafter, as an example without any limitative character, a preferred form of embodiment of a road bed structure according to the invention is described, with reference to the accompanying drawings, wherein:
  • figure 1 represents a cross-section of a road, street or the like, realized according to the invention;
  • figures 2 and 3, at a larger scale, represent the parts indicated by F2 and F3 in figure 1, figure 4 represents a cross-section according to line IV-IV in figure 3;
  • figure 5 represents a perspective view of the foil with nubs, such as applied in a road bed structure according to figures 1 to 4;
  • figure 6 is a view similar to that of figure 4, however, for an embodiment variant;
  • figure 7 represents a perspective view of the foil with nubs, such as applied in a road bed structure according to figure 6.
  • The road bed structure according to the invention substantially consists of a soil track 1, onto which a foundation 2 is placed, which is formed, for example, by lean concrete, gravel or the like, on which, in this embodiment, a foil 3 with nubs is provided.
  • On this latter, subsequently the laying bed 4 is provided, which consists of gravel, sand, a mixture of sand and cement, a ternary sand mixture or mortar or the like, into which finally the small-scaled elements 5 are placed.
  • The different elements are arranged with an inclination towards one or more lateral edges of the street, road or such, whereby this inclination will be, for example, 2 %.
  • At the lateral edges of the thus formed street, road or such, kerbstones 6 and 7 can be provided, which, for example, are placed in a bed of lean concrete 8.
  • On the lowermost part of the thus formed road bed structure, in the lean concrete 8 preferably a drainage conduit 9 is provided which gives out to a ditch, sewer or the like 10.
  • The foil 3 with nubs in this case consists of a foil 11 of synthetic material, on which, at regular mutual interspaces, in longitudinal direction as well as in transverse direction, nubs 12 are provided, for example, with a cylindrical and/or conical cross-section, whereby a water-permeable foil 13, for example, a fabric of synthetic material or a geotextile, is provided on the nubs 12.
  • Of course, such nubs 12 may show any other cross-section.
  • The foil 3 with nubs may be realized, for example, such that the foil 13 has a thickness of approximately 1 mm, whereas the foil 11 with the nubs 12 may have a height of approximately 5 to 10 mm.
  • In this manner, it is obtained that, over the entire surface of the road, street or such, between said nubs 12, so to speak passages or tiny channels 14 are formed, in such a manner that the rain water penetrating through the joints between the small-scaled elements 5 up into the sublayer, immediately is drained through those tiny channels 14 towards the lateral edge of the road or such in order to end up in this manner, for example, through the porous lean concrete 8, in the drainage conduit 9 in order to be removed by means of said ditch, sewer or such 10.
  • In general, therefore it may be stated that according to the invention, a water drainage is formed above the foundation of the road, towards a lateral edge of the road, where the collected water is received and drained off.
  • Connected thereto, in figures 6 and 7 an embodiment variant is represented, whereby the foil 11 is provided with hollow, or, in the represented form of embodiment, full nubs 12, which are placed directly onto the foundation 2 in order to form said tiny channels 14 and whereby in this case, the foil 11 is provided with holes 15 in order to render the foil 11 permeable for water.
  • It is clear that instead of the foil 3 with nubs, to the same end and result a foil may be applied on which ribs, positioned parallel to each other, are provided, between which ribs the tiny channels 14 are formed.
  • Evidently, the present invention is not limited to the embodiment described in the aforegoing and represented in the drawings, however, such road bed structure may be realized in a variety of forms, dimensions and compositions, without leaving the scope of the invention.
