Definitions

  • the invention relates to a superstructure of a road, path, square or the like, wherein the superstructure comprises several strip-shaped structural elements.
  • Such a superstructure is, for example, made of the GB 194 347 A They have become well-known. All components are identically shaped and have inclined side surfaces.
  • the EP 3 101 176 A2 discloses a method for producing a road structure, wherein the ground or a layer is profiled so that an arch-like elevation is created.
  • the superstructure forms the uppermost part of the road structure. It is laid directly on the previously constructed substructure or on natural ground, with the so-called subgrade located between the substructure and the superstructure.
  • roads are often renewed under a partial closure in order to at least partially maintain traffic on the relevant section of the route.
  • the object of the present invention is therefore to provide a superstructure for a road, path, or square that can absorb traffic loads particularly well and over a long period, and to provide a method by which such a superstructure can be produced.
  • this problem is solved by a superstructure of a road, path or square with the features of claims 1 and 8.
  • the angled side surfaces allow the strips to wedge together, significantly improving the load-bearing capacity of the superstructure compared to current technology.
  • the strips interlock so tightly that their load-bearing capacity even surpasses that of a completely intact slab.
  • Such a superstructure not only has a longer lifespan but is also particularly easy to manufacture. While the use of modified equipment is possible and advantageous, it is not strictly necessary. Conventional equipment currently available on the market can also be used for this specific type of base course production.
  • a special feature of the construction process is... During road rehabilitation or utility relocation work in an existing road, the bound or unbound material is removed in strips, and the new building material is immediately installed in the same strips.
  • a strip as defined by the invention, is present when the length of the building element is equal to or greater than its width, with the width being the direction in which another type of building element adjoins it, for example, the direction in which an intermediate strip adjoins a foundation strip.
  • Trenches can be excavated in a linear pattern and immediately refilled with a setting or hardening material. Suitable materials include concrete or asphalt. The material in a refilled trench can harden before the adjacent trench is excavated and refilled.
  • the principle of interlocking strips can also be applied to the already more subdivided concrete paving construction.
  • the principle of interlocking the stones can also be implemented with staggered joint patterns.
  • the slopes of the outer edges do not require parallel strips of equal width, but simply a coordinated geometry between adjacent stones.
  • the crown strip is symmetrical with respect to a central longitudinal plane.
  • the entire superstructure can be symmetrical with respect to the central longitudinal plane of the crown strip. This makes it especially easy to construct a vault support layer.
  • the upper surfaces of the structural elements can form a flat surface. This makes it particularly easy to apply a flat top layer.
  • the building elements can be made of a hardening or setting material, in particular concrete or asphalt.
  • the superstructure is designed, at least in one area, as a wedge-shaped, interlocking vault.
  • the intermediate strips and foundation strips can be wider than the crown strip(s).
  • the crown strips result from the existing or desired road width as a residual strip compared to the foundation strips and intermediate strips, which are approximately the same width. Specifically, they can have a width ranging from 10 cm to 1 m.
  • the intermediate strips can have widths ranging from 0.5 m to 1.5 m.
  • the foundation strips can have widths between 0.5 m and 2 m and depths ranging from 20 cm to 80 cm.
  • the crown strips can be higher than adjacent intermediate strips.
  • they can be designed so that they form an interlocking pattern at the bottom by means of a small undercut, thus interlocking against vertical upward lifting.
  • the superstructure features at least one wedge arch, comprising at least two foundation strips, two intermediate strips, and a crown strip.
  • At least one further wedge arch can be provided, also comprising at least one foundation strip, two intermediate strips, and a crown strip.
  • an entire road width can be constructed with two wedge arches, with each half of the road having its own wedge arch and the two halves sharing a central foundation strip.
  • the superstructure has a road surface on the top of the structural elements.
  • This can, for example, be made of asphalt.
  • a superstructure can be applied to the strips.
  • an existing superstructure can be milled off or a road can be demolished.
  • Utility lines can be installed before the trenches are dug.
  • the separating opening cuts of the trench walls in the bound superstructure could be incorporated diagonally into the existing bound superstructure, depending on their position in the cross-section, as foundation strips, intermediate strips or crown strips.
  • At least one or more wedging strips would be constructed when closing the construction areas.
  • the remaining road sections would remain in their original condition until they require repair. This allows the infrastructure to be gradually upgraded during utility work or partial renovations.
  • a superstructure according to the invention can be produced by producing at least two strips simultaneously and using a slipform paver.
  • a slipform paver can produce all strips simultaneously by producing leading strips whose walls are coated with a release agent, and then immediately filling in the remaining intermediate strips.
  • a trailing smoother can then apply the finish to the entire surface of all the still-fresh strips at once.
  • a wedge arch constructed in two halves of the road has no final weak point in the middle of the road.
  • the process can be further refined by spraying freshly milled or exposed flanks of the already installed and hardened strips with bituminous material before the subsequent strips are applied. This serves to retain water during the setting of the newly applied material, to distribute stresses from later compressive forces without stress peaks, and to seal the joint surfaces in the finished wedge arch formed from the strips.
  • Additional angled recutting of the already hardened material in one of the previously excavated trenches can be carried out if the stability or shape of the trench excavation or defects have led to an unsightly joint shape.
  • joint patterns can also be created using vibrated joints to achieve even better shear strength.
  • a desired reduced grid spacing can also be optimized so that hydraulically bound materials can be covered with just a thin layer of asphalt.
  • the joint design could also be optimized in this way.
  • the road is produced with small-scale fractures but with precisely defined three-dimensional fracture points, so that these cracks cannot spread apart and the structure remains intact.
  • the Figure 1 Figure 1 shows the superstructure 1 of a road.
  • the superstructure 1 comprises foundation strips 2, crown strips 3, and intermediate strips 4.
  • the two outer crown strips 2 have only one inclined side surface 5, while the other strips 2, 3, 4 have two inclined side surfaces.
  • the side surfaces of the remaining strips 2, 3, 4 have an angle to the vertical that is greater than 0° and less than 90°.
  • the inclination of the side surfaces of adjacent strips 2, 3, 4 is aligned with each other. Due to the inclined side surfaces, the strips 2, 3, 4 are wedged together.
  • Strips 2, 3, 4 are made of a hardening or setting material, in particular concrete or asphalt.
  • the vertex strips 3 have a narrower width than the intermediate strips 4 and the foundation strips 2.
  • strips 2, 3, 4 in the left half form a first wedge arch 6, while strips 2, 3, 4 in the right half form a second wedge arch 7. Both wedge arches 6, 7 share the central foundation strip 2.
  • the entire road therefore has two wedge arches 6, 7.
  • One wedge arch 6, 7 is provided for each half of the road.
  • strips 2, 3, 4 form a flat surface on which a road surface 8 is laid.
  • the foundation strips 2 have a top surface O that is narrower than their bottom surface U.
  • the intermediate stripes 4 have a top surface O that is wider than the bottom surface U. The same applies to the vertex stripes 3.
  • the Figure 2 Figure 1.1 shows a second embodiment of a superstructure.
  • Two intermediate strips 4 are arranged between the foundation strips 2 and the crown strips 3.
  • Two wedge arches 6, 7 are also formed.
  • the foundation strips 2 also have side surfaces inclined to the vertical, to which an intermediate strip 4 with a correspondingly inclined side surface is attached.
  • the intermediate strips 4 are also designed such that the upper surface O has a greater width than the lower surface U, but that the upper and lower surfaces O, U are aligned parallel to each other.
  • the The top and bottom surfaces O, U of the intermediate strips 4 are not aligned parallel to each other. This only applied to the foundation strips 2 and the apex strips 3.
  • the Figure 4 shows various work steps that must be carried out to rehabilitate a road and install a superstructure according to the invention.
  • FIG 4a A working level 10 is created by milling with a milling machine. Subsequently, a trench 11 for a foundation strip is excavated in the center of the road using an excavator or a milling machine, see Figure 4b .
  • Trench 11 is filled with road material 12.
  • the road material 12 is compacted and leveled to the working level 10.
  • trench 13 is also excavated using an excavator or milling machine.
  • a portion of the road material 12, which forms a foundation strip 2 is removed, creating a sloping side surface 5.
  • Trench 13 is excavated in such a way that a bottom surface U is inclined to the horizontal and a side surface S is inclined to the vertical.
  • Trench 13 is filled with road material, creating an intermediate strip 4.
  • the road material is also compacted and leveled to the working level 10.
  • a trench 14 will be excavated for another foundation strip.
  • This trench 14 will be constructed according to Figure 4e The trench is filled with road material, compacted, and leveled.
  • another trench (15) is excavated for a further intermediate strip, again creating appropriately sloping side surfaces.
  • FIG. 4f After filling trench 15 with road material, creating an intermediate strip 4 (see Figure 4f A trench 16 is excavated for a summit strip. This is shown to Figure 4g It is filled with road material, compacted, and then leveled again.
  • a wedge vault has been completed on the left side of the street.
  • another trench 17 is excavated to the right of the central foundation strip 2 for an intermediate strip with sloping sides. This will, as can be seen from the Figure 4h
  • the trench is filled with road material and compacted.
  • a further trench (18) is then excavated for a right-hand foundation strip.
  • Figure 4i The trench is filled with road material and compacted. After the road material has hardened, another trench 19 is excavated for an intermediate strip. After trench 19 is filled with road material and compacted, a trench 20 is excavated, again using, for example, an excavator or milling machine, and then, see... 4k figure , filled with road material. A road surface 21 is then applied, see 4k figure .
  • FIG. 5d A trench 35 was excavated in the center of the remediation area using an excavator or milling machine.
  • This trench 35 which is intended for a crown strip, will be, according to the information provided, Figure 5e
  • the trench was filled and compacted with road material.
  • Trench 35 was already created with appropriately sloping sides.
  • Trench 36 is shown to be... Figure 5f
  • the trench was filled with road material and compacted.
  • a trench 37 was excavated for a foundation strip. This was, according to the information provided, Figure 5g The area is filled and the fill material is compacted.
  • a trench 38 is excavated on the left side of the summit strip 3 for a further intermediate strip.
  • This trench 38 is shown in the Figure 5h
  • the area is filled and compacted with road material.
  • a trench 39 is excavated for another foundation strip. This will be, according to the information provided... Figure 5i
  • the area is filled and compacted with road material. A road surface can then be applied.
  • FIG. 6d Two foundation strips 2 and one crown strip 3 were produced using a slipform paver.
  • a slipform paver can produce strips 2 and 3 simultaneously by producing leading strips whose walls are coated with a release agent. The remaining intermediate strips can then be filled immediately afterwards, see [reference].
  • a trailing smoother can perform the finishing on the entire surface of all still fresh stripes simultaneously.
  • the inventive method provides that trenches can be created both vertically from top to bottom and diagonally from top to bottom using milling and excavating equipment.
  • a trench excavated in loose building material will settle slightly, resulting in sloping walls rather than vertical ones. Inclines exceeding this natural slope angle can be further shaped. Due to its settling properties, loose material can also be excavated under or beside an overhanging slope.
  • Trenches milled or cut diagonally through bonded or hardened material remain standing even with overhanging walls without collapsing.
  • Milling machines can also remove or mill away sections of previously placed and already hardened material such as concrete or HGT (high-density concrete).
  • the consistency of fresh concrete and HGT can be controlled so that, when manufactured using slipform pavers, walls with inclined and even slightly overhanging shapes can be produced.
  • self-locking wedge arches can be economically produced in both new construction and renovation projects using milling machines, excavators, and slipform pavers.
