Definitions

  • the invention relates to a method for producing bituminous coverings for roads, paths and the like in the cold process, wherein layers containing bitumen emulsion and optionally grit and other additives are deposited on a solid surface (subgrade, existing road surface, etc.) such as sand, cement and the like are applied.
  • a solid surface such as sand, cement and the like are applied.
  • the invention further relates to coverings produced thereafter.
  • Cold mix coverings tend to deform under heavy traffic loads. They have a very high void content, are not dense on the surface and take a very long time to reach their final strength. The latter is caused, among other things, by the necessary high so-called flux content.
  • Drinking blankets have a small bonded layer thickness and the coating of the mineral is not complete.
  • Such ceilings have a low load-bearing capacity, are very prone to deformation, it is difficult to check the installation quantities and the flatness depends on the shape of the plan.
  • the use of the binder is poor and there is a risk of the formation of binderless mineral layers.
  • the quality of such blankets is dependent on the weather.
  • Bitukiese have a high energy requirement and cause odor and transport nuisance when installed. If the material is transported over long distances, there is a risk of it being installed too cold. Also disadvantageous is the risk of the binder overheating, which leads to embrittlement. After cooling, the bituminous gravel acts as a rigid plate. If the binder content is too low, the surface may become lean, which in turn causes surface water to penetrate.
  • Soil stabilization suffers from the changing nature of the soil material. Furthermore, high mechanical energy consumption is necessary. Due to the presence of fine particles in the soil material, a homogeneous covering is not possible. The binder is not used optimally and the nature of the soil stabilization depends on the weather.
  • the present invention has for its object to provide a method for producing bituminous coverings which avoids the disadvantages mentioned above and is energy-efficient by using the cold construction.
  • the binder utilization should be improved and a high tightness on the surface should be achieved. Thanks to the high level of flexibility, substructure movements should be absorbed without the formation of cracks.
  • the method should make it possible to use conventional road construction machines. The visual impression compared to previous cold construction methods should be better, since precise lateral delimitation is made possible by the installation with finished products. Furthermore, the installation should be largely independent of the weather and should also be possible in cool, humid and damp weather, whereby there should be no loss of binder due to washing out after rain.
  • the method according to the invention is characterized in accordance with claim 1, characterized in that at least one layer I containing a charge-active bitumen emulsion and at least one layer II containing an oppositely charged bitumen emulsion are applied to the solid substrate.
  • a frost-proof grade 1 made of gravel is provided.
  • a gravel slab 2 which consisted of a layer 100 kg / m 2 with 2% anionic bitumen emulsion mineral 5/40 (100% broken), was applied.
  • the pre-coated mineral was installed with a paver so that straight edges were achieved. Installation with a grader or grit spreader is also possible.
  • the gravel slab 2 was compacted with a conventional roller with a weight of 4 to 7 tons.
  • next layer 6 2 to 3 kg / m 2 of likewise cationic 65-70% bitumen emulsion were applied by means of a ramp spraying device.
  • the cold asphalt surface made in this way has all the desired advantages.
  • the bituminous layer 2 results in the layer I, which here is composed of an anionic bitumen emulsion and the corresponding minerals.
  • Layers 3 to 7 form layer II, which contains the oppositely charged cationic bitumen emulsion.
  • the cold asphalt surface described in Example 1 is particularly advantageous in terms of its overall structure.
  • the grain structure is such that the largest grain diameter has 80% of the layer thickness. Only 100% broken material was used.
  • the smallest grain diameter should not be less than 10% of the layer thickness and the gradation of the grain distribution should be continuous from the smallest grain to the largest grain.
  • an optimal load-bearing capacity is obtained with the smallest possible void and binder requirements. The result is a good support effect and optimal readiness for compaction with little compaction work. With this cold installation method, there is a recompression by traffic.
  • the mineral can be mixed with the bitumen emulsion on any suitable, continuous or discontinuous mixing plant.
  • the layers 6, 7 serve to achieve the desired layer thickness and can be repeated or omitted as desired.
  • a thin-layer covering was applied in a cold process to an existing concrete pavement.
  • a conventional cold thin-layer covering 10 was applied to the pre-injection material, which contained cationic bitumen emulsion, grit and sand.
  • the emulsion breaks away so quickly and quickly and permanently sets between the thin-layer covering and the concrete surface.
  • the process according to the invention improves the adhesion of the road surface.
  • the marketability is increased and is reached faster.
  • Bituminous ceilings can be sealed well with the present method. Ruts of old coverings can be filled in satisfactorily.
  • the covering can also be applied in colder weather than was previously the case.
