Definitions

  • the invention relates to a soil cover according to the preamble of claim 1. Furthermore, the invention relates to a method for producing such a soil cover according to the preamble of claim 7.
  • the invention is concerned with the creation of pavement surfaces as a covering or as a top layer of a traffic area in road and road construction.
  • the paved area consists of the actual paving stones, which are laid in a plaster bed and the underlying support layer. Instead of paving stones and paving slabs can be used. In addition to natural stones and artificial conglomerates for the top layer into consideration, such as concrete blocks, clinker or the like.
  • bonded construction and the "unbound construction method”.
  • the stones are placed on a loose bed of grit, sand or granules.
  • the areas between the form stones, so-called joints, are filled with a grout material.
  • This overall design responds to static or dynamic loading with elastic deformation. Temperature stresses are reduced by unhindered deformation, so that no constraints arise.
  • the plaster ceiling remains basically permeable to water.
  • the paving bed and the joints may for example consist of a cement mortar.
  • Disadvantage of this design is the risk of damage due to deformation of the soil cover.
  • the plaster ceiling in this case is almost impermeable to water.
  • the closest prior art is the DE 696 27 642 T2 considered.
  • the cement asphalt mortar comprises an asphalt emulsion which may contain a polymer.
  • the CA mortar may contain quartz sand.
  • paving stones are placed on a prepared granule layer and then poured a cement-asphalt mortar in the interstices of the paving stones. Since the CA mortar is pourable and flowable, it can at least partially flow through the intermediate spaces of the paving stones into the underlying granulate layer or into intermediate spaces of the individual granulate particles (FIG. 8). In this way, the CA mortar forms, together with the granules, a sort of paving bed similar to that of the present invention.
  • the WO 2009/144293 A1 relates to a setting and hardening accelerator for hydraulic binders. These are used, for example, so that concrete or reinforced concrete structures, which are also created with reference to roadway rehabilitation, can harden and load as quickly as possible. Paving or the use of paving stones per se are not addressed in the Scriptures. On this basis, the invention is based on the task of further developing soil covers of the type mentioned. To achieve this object, a Erdreichabdeckung invention has the features of claim 1. It is therefore envisaged that the paving bed consists of a mixture of an aggregate with an additive and a binder (bitumen). The additive used is a mixture of a polymer with quartz sand.
  • the polymer is a polymer based on Polycarboxylatether. Furthermore, the polymer is processed in a dry state and with a powdery consistency. The installation of the mixture takes place in cold installation. First, the aggregate is mixed with the additive and then the binder is added. The mixture of components takes place in the hot state, whereas the installation takes place in cold installation.
  • a cold incorporation means processing and installation in a temperature range from 0 ° C. to 80 ° C., preferably at ambient temperature.
  • the soil cover according to the invention furthermore has the particular advantage that the accumulated rain water can only very slightly penetrate into the supporting structure of the soil cover compared to the unbound construction. In this way, the application possibilities for soil coverings based on paving stones are extended.
  • the system behaves by the binder bitumen like a soil cover in elastic construction.
  • Joints between the bricks can be filled with a joint filling material from an aggregate, or with a joint filler made from a mixture of an aggregate with the additive and a binder.
  • the binding of the aggregate with the bitumen immobilizes, above all, the fine particles of the aggregate.
  • the bitumen-bound aggregate is less stressed in the system than conventional unbound aggregate.
  • An inventive method comprises the measures of claim 7.
  • a building material mixture to be prepared cold is made of an aggregate and an additive and a binder and that the processing of the mixture takes place in Kalteinbau and that the paving or the stones (directly) on the pavement be laid, which (directly) is applied to a support layer.
  • the additive used is a mixture of a polymer with quartz sand.
  • the mixing order namely first a mixing of the aggregate with the additive and then the addition of bitumen as a binder.
  • the paving bed is installed over-inflated so that after compaction of the paving bed the soil cover identifies the intended height.
  • the quartz sand has a grain size of 0.1 to 2.0 mm, in particular from 0.1 to 1.0 mm.
  • the quartz sand has an average particle size of 0.27 to 0.79 mm.
  • the binder is bitumen.
  • the polymer has a content of 0.05 to 0.3 wt .-% of the binder content.
  • the polymer In order to achieve a uniform mixing, the polymer must be mixed with at least 450 g of quartz sand.
