Definitions

• the invention relates to a floor covering for roadways and ways to apply to a subsoil.
• the flooring has a multi-layered structure with a top and bottom, wherein the superstructure of the floor covering is a combination of compacted, solid aggregates and organic adhesives.
• the invention further relates to a roadway with a top and bottom, which are applied to a ground.
• Such floor coverings or roadways are known from DE 196 05 990 A1 and DE 197 33 588 A1.
• a disadvantage of asphalt coverings which are produced from a mixture of bitumen and gravel, is their sensitivity to oil and gasoline, the lack of color stability and their poor environmental compatibility. In the case of renewal of the roadway, the remains must be disposed of as hazardous waste. If color-coded paths are required, as is the case, for example, with bus lanes or cycle paths, expensive color layers must be applied, the color of which deteriorates over time due to aging, erosion and exposure to light, so that the color layer must be renewed, which is again expensive.
• Coverings with a uniform and visually appealing surface structure are known from DE 20 2004 001 884 U1.
• the water-permeable surface is made of mineral aggregates and organic adhesives.
• the mixture is installed in the not yet cured and deformable state.
• Suitable adhesives are organic adhesives which, together with mineral additives, are mixed to form a batch and processed before curing.
• the superstructure of the floor covering is formed from a combination of compacted, solid aggregates and organic adhesives, wherein the building material of the aggregates at least a predominant proportion of glass and the adhesive is provided with a dye. Due to the light-conducting property of the glass particles of the compound, the color of the adhesive is always passed from glass particle to glass particle to the surface, so that the dyeing even if the glass particles are abraded or the adhesive is dirty or cloudy on the surface. As a result, a permanent color stability is ensured even with abrasion of the surface. The flooring thus permanently retains its attractive or signaling color.
• the dynamically acting loads from the rolling traffic and the predominantly static traffic forces from the stationary traffic cause pressure, tension and shear stresses in the roadway fastening.
• the superstructure of the roadway absorbs these stresses and distributes them harmlessly to the lower layers.
• the high pressure resistance of the building material makes it particularly suitable for the design of carriageways.
• the proof of compressive strength is provided as follows:
• Compressive strength was determined according to DGGT Recommendation No. 1 as a uniaxial compression test on a prism sample.
• the prism samples had the dimensions 40 x 40 x 160 mm and resulted in the following result:
• the flooring was very resistant to continuous load, even when exposed to heat.
• the above-mentioned values can be achieved both with glass beads and with glass breakage or a mixture thereof for the aggregate.
• the open-pore structure of the superstructure especially when using glass breakage, leads to high coefficients of friction on the surface, so that the floor covering is particularly suitable as a non-slip ceiling for roadways, sidewalks, stairs and presentation rooms and thus reduces the risk of accidents. Further improvement in abrasion resistance can be achieved by admixing short cut fibers of glass.
• the grain size of the aggregates has a significant impact on the infiltration performance of the flooring.
• Particularly preferred are aggregates whose average size of the grain is between 1 and 7 mm.
• the layer structure of the floor covering according to the invention has a favorable influence on the mechanical strength values, so that even values of more than 5 mm are possible for the average size of the grain without a significantly increased risk of breakage occurring. With this grain diameter, the infiltration performance can be further increased. Moreover, at these values, the decrease in infiltration performance due to the input of mineral and organic fines remains low over time.
• the grain size of the gravel in the substructure Another favorable influence on the water absorption value and water regulation capacity of the soil is the grain size of the gravel in the substructure. This promises excellent values for an average grain size for the undersize of 5 mm or more. Proven average grain size of the gravel k ⁇ i it be in a range between 5 mm to 16, 16 to 22 mm or 16 mm to 32nd That is, the gravel layer is composed of gravel with different grain sizes, wherein the grain of a ballast layer is located in one of said areas. In general, the particle size distribution is defined according to DIN 66145. The parameter n is at least 9 and is determined neglecting 1% oversize and undersize each.
• the adhesive is preferably a two-component polyurethane adhesive. Also useful is a two component epoxy resin or a one component polyurethane adhesive. Polyurethane adhesives are characterized by a complete UV light resistance, while epoxy resin adhesives have a high adhesion especially on asphalt. Suitable adhesives are offered, for example, by the company TerraElast AG, which have developed adhesive systems that are specialized for the particular application.
• the flooring according to the invention has no toxic effect on molds and is considered to be difficult to break down microbially. Nevertheless, eluable substances can be well degraded from the flooring, as material trials have shown. As evidenced by washing tests, there is no chemical interaction between surface water and the covering material, so that surface water which seeps through the covering can be discharged untreated into the sewage system or can safely drain into the groundwater. Finally, the flooring according to the invention can be disposed of after its use phase in a soil or gravel washing system without adverse environmental effects. Alternatively, after comminution, reuse as granules is also possible.

• the grain size of the additives is chosen so that the road surface of the strip is impermeable to water. This ensures that the strip, which is bordered on the edge of the old road surface, is not filled with surface water during precipitation, which could lead to erosion in freezing due to bursting of the frozen areas.
