Definitions

  • the invention relates to a method for producing bituminous pavement ceilings on bridges with pavement slabs made of metal or concrete, in which one or more adhesive and insulating layers made of hardening plastic are applied between the pavement slab and the pavement slab, at least in the upper layer before Hardening is sprinkled with granules.
  • Bridges in steel or reinforced concrete construction are provided with pavements made of bituminous mix. Cracks can occur with these bituminous coverings, so that rainwater and de-icing salt water can penetrate and destroy the pavement slabs. Insulating layers made of hardening plastic are therefore applied to the carriageway slabs to protect them from corrosion. However, since the adhesion between the hardened plastic layer and the asphalt layers is mostly low, the surface of the plastic layer is roughened in order to obtain a positive connection.
  • DE-PS 840 400 proposes to sprinkle grit or steel chips in the still liquid plastic layer. However, due to their high density, these granules sink to the pavement slabs. This creates leaks in the insulating covering.
  • DE-PS 12 40 547 proposes a two-layer plastic layer consisting of an insulating and an adhesive layer, into which chippings are scattered. Because of the high expenditure, a fabric web is inserted into the still liquid plastic layer in DE-PS 22 23 641, in order to prevent the grit from sinking through. Since this method also appeared to be too complex, it was proposed in DE-OS 24 50 987 to use a plastic with a thixotropic flow behavior.
  • the adhesion between the plastic layer and asphalt can also be improved by mechanically deforming the plastic surface, such as by rolling grooves (DE-PS 850 458) or by inserting a reinforcing layer made of a non-woven material, the lower part of which is made of the liquid plastic and the upper part of which the bitumen is penetrated (DE-OS 27 91 885).
  • hairline cracks can occur in the insulating and adhesive layers. There may be several reasons for this. Different coefficients of thermal expansion and different moduli of elasticity of the road slabs on the one hand and the plastic layer on the other hand are certainly also to be regarded as reasons for hairline cracks.
  • DE-OS 23 54 913 therefore proposes a two-layer plastic coating with sprinkled grit, in which a plastic that remains elastic after heating to 240 ° C. is used. This process is also very complex and severely limits the selection of suitable plastics.
  • the invention has for its object to develop a novel method for the production of road surfaces, in which the aforementioned difficulties are avoided and in addition to an excellent adhesion between the plastic layer and bituminous outer layers, an elasticization of the boundary layer is achieved so that hairline cracks are bridged.
  • the granules consist of at least one material which is in the molten state at the installation temperature of the bituminous mixture and which binds to the bitumen and the plastic layer.
  • Solvent-free epoxy resin systems with suitable hardeners and polyurethane resins or their respective tar or bitumen combinations, which are optionally provided with fillers, are preferably used as the hardening plastics for the adhesive and insulating layer.
  • suitable hardeners and polyurethane resins or their respective tar or bitumen combinations which are optionally provided with fillers, are preferably used as the hardening plastics for the adhesive and insulating layer.
  • suitable hardeners and polyurethane resins or their respective tar or bitumen combinations which are optionally provided with fillers, are preferably used as the hardening plastics for the adhesive and insulating layer.
  • other curing plastics known to the person skilled in the art can also be used.
  • the granules consist of thermoplastic or elastic polymers or their bitumen combinations and have a melting point in the range of approximately 40-150 ° C., preferably between 70 and 120 ° C.
  • the melting point must be matched to the intended bituminous covering.
  • the chemical structure of the plastic granules must be such that they are well compatible with both the hardening plastic system of the adhesive and insulating layer, e.g. Tar-epoxy resin combinations with predominantly aromatic structures, as well as with the aliphatic structures of the bituminous coverings.
  • the homopolymers or copolymers can be used either in pure form or in admixture with other polymers, with bitumen, natural resins, oligomeric hydrocarbon resins, synthetic rubber or plasticizers.
  • the grain size of the granules should be selected so that 90% by weight is in the range from 1 to 10 mm, preferably between 3 and 6 mm.
  • the road slabs are treated in the usual way with a suitable low-solvent primer in order to bind the dust on concrete slabs or to prevent corrosion on steel slabs.
  • a suitable low-solvent primer in order to bind the dust on concrete slabs or to prevent corrosion on steel slabs.
  • an adhesive and insulating layer made of hardening plastic is applied in a layer thickness of 1 to 5 mm, preferably 2 to 3 mm, into which 0.5 to 1.0 kg / m 2 of the granules are sprinkled. Because of its low density compared to chippings, the granulate used according to the invention sinks only a little into the adhesive and insulating layer, so that it does not touch the surface of the carriageway slab. After curing, the unbound granulate can be swept off.
  • the bituminous mix When the bituminous mix is installed, the granulate is melted and forms a homogeneous, force-locking connection between the plastic layer and the asphalt, which is able to easily bridge hairline cracks.
  • the asphalt also penetrates into the depressions in the adhesive and insulating layer and thus forms an additional positive connection.
  • the deck of a concrete bridge is impregnated with 0.5 kg / m 2 of a low-solvent primer based on liquid epoxy resins.
  • the primer has the following composition:
  • the deck of a steel bridge is derusted and cleaned in accordance with the regulations. Then 500 g / m 2 of an anti-rust primer based on solid, high-molecular epoxy resins (Orthoflex PR 1116; Strabag-Bau AG) are applied. After the primer has hardened, the road surface is coated with 2 kg / m 2 of a solvent-free mass based on liquid epoxy resins (Orthoflex BC, Strabag-Bau AG).
  • thermoplastic granulate based on a bitumen-modified ethylene copolymer (Lucobit; BASF) with a grain size of 2 to 3 mm and a melting point of 95-105 ° are sprinkled into the still liquid adhesive and insulating layer C.
  • a road surface made of rolled asphalt is installed in a known manner.
