Definitions

  • the invention relates to a method for manufacturing a two-layer asphalt surface with one Optimization of the properties of the asphalt layers is effected.
  • binder layer has to withstand today's stresses the main task due to heavy traffic, the shear stress record and derive without damage. Out for this reason, binder layers have to be in the first place be steadfast.
  • the asphalt base layer is used for damage-free absorption and derivation of the occurring voltages in the areas below. You also have to to be stable.
  • Binder and base layers are covered by the top layer protected and therefore have no sealing tasks.
  • cover layers are in one 4 cm thick built-in.
  • the nominal thickness of the binder and asphalt base courses vary depending according to the construction class Building regulations, such as RStO 86/89. / Arand and others : Investigation of the effectiveness of high-performance compaction screeds through ongoing field measurements Construction sites, road and highways, Bonn 41 (1990) No. 5 pp. 215-219.
  • the top layer is due to the sealing function the layer rich in binder, at the same time the highest possible temperatures occur here on. Due to the thermoplastic properties of bitumen has the top layer material in summer the least shear strength.
  • the quality is subject to the Road distributed or mixed components larger Fluctuations compared to those caused by the mixing process asphalt produced on an asphalt plant, because the ratio of old and new components is less is to be strictly observed and is often different in the construction lot Compositions are present.
  • DE-A-2 416 338 describes nailing a carrier asphalt concrete immediately after the application of the carrier asphalt concrete at a time when it is still hot.
  • the publication AU-B-464 167 describes the joint heating and mixing of two different mixture sensors which are then mixed together and applied in one layer.
  • the invention has for its object a method for the production of a two-layer asphalt surface from two ready-to-deliver mix types with which the total paving thickness is essential increases and the layer thickness ratio the composition and thus optimized properties will.
  • the optimization relates in particular to the degree of compression without increasing the compression energy.
  • this object is achieved in that the upper layers of the asphalt pavement hot-installed in one operation and the layer thickness ratio with each other is changed.
  • the direct hot-on-hot installation ensures an optimal bond between the layers.
  • the deformation behavior associated with lateral deflection (sliding) is thus improved.
  • the simultaneous installation in two layers allows the asphalt formulations to be changed to more stable and mixtures, since the level of compaction in both layers of the asphalt is increased considerably and the void content can be reduced at the same time.
  • the economic advantage is the reduction of the expensive cover layer material.
  • Improved binders and / or more polish-resistant chips can also be used.
  • a high storage density can only be achieved with sufficient installation thicknesses. In general, this requires a ratio of layer thickness to largest grain of approx. 3: 1 in the traditional construction method. This results, for example, in the installation thickness of 4 cm for asphalt concrete 0/11 mm.
