Definitions

  • the invention is based on a reinforcement mat for reinforcing an installation layer in road and path construction with a net- or grid-like textile surface structure which has at least one pressure body, wherein the pressure body is designed to absorb loads from the installation layer or a layer located above it.
  • fleece or geotextile grids have been inserted. These reinforcements are intended in particular to stabilize paving layers and, for example, to distribute spatially limited loads over larger areas.
  • the EP 0 021 532 A1 discloses a mat having loops made of a different material than the material from which the mat is made. These loops are pliable and flexible.
  • T2 is an earthwork grid that is intended to be used as a reinforcement mat.
  • the earthwork grid has a net or grid-like textile surface structure whose nodes are raised.
  • the problem here is that the earthwork grid can only absorb relatively small loads via its nodes.
  • the earthwork grid is essentially flat, there is only a small amount of mechanical interlocking across the aggregate of the installation layer. The earthwork grid is therefore only partially suitable for stabilizing the installation layer.
  • the object of the invention is therefore to offer a reinforcement mat which improves the stabilization of an installation layer surrounding the reinforcement mat and, if applicable, layers lying above it.
  • the pressure body can act as a spacer, for example to other adjacent layers.
  • the pressure body can act as a load-guiding element and absorb loads from the installation layer and/or transfer them to surrounding layers.
  • the textile fabric can be used to spatially position the pressure body during installation. After installation, the textile fabric can be used, in particular, to transfer loads absorbed by the pressure body to other pressure bodies and/or another textile fabric. Several pressure bodies can thus be connected to one another in a tensile manner via the textile fabric, in particular for the purposes of load distribution. This is particularly important because unbound material can only transfer loads via compressive forces.
  • Mesh sizes of the textile fabric can be uniform. Several or different mesh sizes can also be provided. For example, adjacent meshes of the textile fabric can alternately have two different predefined mesh sizes, for example a small and a much larger mesh size. Meshes can also be provided, particularly regularly distributed ones, at or in which pressure bodies can be connected to the textile fabric, for example by being screwed in.
  • the height of the pressure body may be at least three times, preferably ten times, the height of the textile fabric.
  • the height of the pressure body can also be selected to be significantly greater, for example 100 times greater, than the height of the textile fabric.
  • the three-dimensional structure enables the material of the installation layer to interlock with the reinforcement mat.
  • the height of the pressure body can also be selected depending on the height of the installation layer. If the installation layer consists of unbound material, the height of the pressure body can be selected between 10% and 100% of the height of the installation layer. If the installation layer contains bound material, the height of the pressure body can be selected between 20% and 50% of the height of the installation layer. It goes without saying that the height of the pressure body can be selected not only depending on the actual height of the installation layer, but also, for example, depending on a typically intended height of an installation layer.
  • the size, in particular the height, of the pressure body can also be selected in a predetermined ratio to the grain size of the material of the installation layer.
  • the pressure body can be made of one or more parts.
  • a multi-part pressure body can have several parts that can be connected to one another by a plug connection, a snap connection, an adhesive and/or screw connection. It is also particularly advantageous if a multi-part pressure body is connected to a textile fabric. It is particularly preferred if the textile fabric is inserted and/or clamped between parts of the multi-part pressure body.
  • the pressure body can be made of stone, concrete, asphalt, plastic and/or steel. These materials are available at low cost and enable the manufacture of a pressure body with the required minimum compressive strength. If the pressure body is made of stone, asphalt and/or concrete, it can have the same or a similar temperature behavior as the material surrounding it with the installation layer. Such a pressure body can also have a high affinity for bonding with the material of the installation layer.
  • the pressure body is solid and/or compact.
  • Solid is understood to mean a design that would fill at least 50% of a cuboid that tightly encloses this design.
  • Conspact is understood to mean a design whose ratio of height to the greatest length of its projection surface is not less than 1:5 and not more than 5:1. The load bearing capacity and the strength of the pressure body can be improved by giving the pressure body a solid and/or compact shape.
  • the durability of the pressure hull can be improved by a solid and/or compact design of the pressure hull. Stress peaks in the installation layer and/or the reinforcement mat can be avoided or at least significantly reduced, for example in concrete layers or generally hydraulically bound layers.
  • the pressure body can have a tensile strength that is at least equal to the tensile strength of the textile fabric. Since a reinforcement mat will in case of doubt tear under tensile load at a point of lowest tensile strength, tearing of the reinforcement mat in the area of the pressure body can be safely avoided.
  • the reinforcement mat can have several pressure bodies.
  • the pressure bodies can be arranged regularly and/or at predefined distances from each other. This allows large-area load bearing and load distribution to be achieved while at the same time keeping manufacturing costs low.
  • At least one pressure body can be arranged on a web between two nodes of the textile fabric and at least one pressure body is designed as a node of the textile fabric or is arranged at a node of the textile fabric. If the pressure body is arranged on a web, it can further increase its tensile strength. If the pressure body is arranged at a node or forms a node, absorbed loads can be distributed simultaneously in different directions, in particular according to the courses of the webs of the textile fabric.
  • the pressure body is connected to the textile fabric by force.
  • it can be inserted into the textile fabric, threaded, pressed, sewn, cast, screwed, hooked and/or screwed to it.
  • the reinforcement mat can have a second textile fabric. This allows the three-dimensional structure of the reinforcement mat to be further developed.
  • the second textile fabric can preferably be connected to the textile fabric by means of the pressure body. Particularly preferably, the second textile fabric can be inserted, threaded, pressed, sewn, cast, twisted, hooked and/or screwed into the pressure body.
  • the reinforcement mat can also have a third textile fabric.
  • the third textile fabric can preferably be connected to the other two textile fabrics by means of the pressure body.
  • the textile fabric and the second textile fabric can engage at end areas of the pressure body, whereas the third textile fabric can engage at a middle area of the pressure body or be connected to it.
  • the third textile fabric can also, for example, alternately engage at the upper and lower ends of adjacent pressure bodies.
  • the reinforcement mat can have an adhesive and/or melting layer.
  • the adhesive and/or melting layer can preferably be arranged on the underside of the reinforcement mat and/or be designed as a cloth-coat layer. It can preferably be applied before the reinforcement mat is installed, for example during the manufacture of the reinforcement mat, particularly preferably to the textile fabric.
  • the reinforcement mat can thus be installed, in particular onto a bonded layer, glued and/or melted.
  • the connecting means can preferably have a high tensile strength. It can, for example, have a rod, a wire and/or a fiber strand. A tensile-resistant connection of the textile fabrics can be realized or formed by the connecting means.
  • a connecting means can be provided with which at least two textile fabrics are connected, for example lashed. This can further improve the stability of the reinforcement mat, particularly in the vertical direction.
  • the connecting means can also further improve the load resistance moment of the reinforcement mat.
  • the scope of the invention also includes a road structure with a reinforcement mat according to the invention and at least one installation layer. This installation layer can preferably consist of rolled asphalt. This asphalt is worked in and compacted using rollers.
  • Fig. 1 shows schematically a road structure 1 with a reinforcement mat 2 according to the invention with pressure bodies 3 and a textile surface structure 5.
  • the reinforcement mat 2 is surrounded by an installation layer 4.
  • the installation layer 4 consists of unbound material.
  • the pressure bodies 3 are made of concrete and have a compressive strength of at least 1 MN/m 2.
  • the Fig. 1 it can be seen that compressive forces F from the installation layer 4 are introduced in particular into the pressure bodies 3.
  • the compressive forces F are converted into tensile forces F', distributed over the textile surface structure 5 or passed on to another pressure body 3 and passed on to lower layers in a spatially distributed manner as load forces F". In this way, the installation layer 4 and the layers above it can be stabilized.
  • the Fig. 2a shows a reinforcement mat 2a.0 with a grid-like textile surface structure 2a.1 and pressure bodies 2a.10.
  • the pressure bodies 2a.10 are connected approximately centrally to the textile surface structure 2a.1.

According to Fig. 3d Material for the pressure bodies to be formed is then injected through openings 3.4 in recesses 3.5 of the lower and upper tools 3.1, 3.3. In this case, depending on the desired material of the pressure bodies to be produced, liquefied, e.g. thermally liquefied, plastic or self-hardening special mortar is injected. After hardening, the lower and upper tools 3.1, 3.3 can then be removed and the finished reinforcement mat 3.0 ( Fig. 3e ) can be taken.
