Description
Die Erfindung betrifft eine Erdreichabdeckung gemäß dem Oberbegriff des Anspruchs 1.
Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung einer solchen Erdreichabdeckung gemäß dem Oberbegriff des Anspruchs 7.
Die Erfindung befasst sich mit der Erstellung von Pflasterflächen als Belag bzw. als Deckschicht einer Verkehrsfläche im Straßen- und Wegebau. Die Pflasterfläche besteht aus den eigentlichen Pflastersteinen, die in einem Pflasterbett verlegt sind und der darunter befindlichen Tragschicht. Statt Pflastersteinen können auch Pflasterplatten zum Einsatz kommen. Neben Natursteinen kommen auch künstliche Formsteine für die Deckschicht in Betracht, beispielsweise Betonsteine, Klinker oder dergleichen.
Hinsichtlich des Aufbaus der Erdreichabdeckung unterscheidet man zwischen der sogenannten "gebundenen Bauweise" und der "ungebundenen Bauweise". Bei der ungebundenen Bauweise werden die Formsteine auf ein loses Bett aus Splitt, Sand oder Granulat gesetzt. Die Bereiche zwischen den Formsteinen, also die sogenannten Fugen, werden mit einem Fugenmaterial verfüllt. Diese Gesamtkonstruktion reagiert auf statische oder dynamische Belastung mit elastischer Verformung. Temperaturspannungen werden durch ungehinderte Verformung abgebaut, sodass keine Zwängungen entstehen. Die Pflasterdecke bleibt grundsätzlich wasserdurchlässig.
Bei der gebundenen Bauweise können das Pflasterbett und die Fugen beispielsweise aus einem Zementmörtel bestehen. Nachteil dieser Bauweise ist die Gefahr von Beschädigungen durch Verformungen der Erdreichabdeckung. Allerdings ist die Pflasterdecke in diesem Fall nahezu wasserundurchlässig.
Als nächstliegender Stand der Technik wird die
Die
Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde Erdreichabdeckungen der eingangs genannten Art weiterzuentwickeln.
Zur Lösung dieser Aufgabe weist eine erfindungsgemäße Erdreichabdeckung die Merkmale des Anspruchs 1 auf. Es ist demnach vorgesehen, dass das Pflasterbett aus einer Mischung einer Gesteinskörnung mit einem Additiv und einem Bindemittel (Bitumen) besteht. Als Additiv kommt eine Mischung aus einem Polymer mit Quarzsand zum Einsatz. Bei dem Polymer handelt es sich um ein Polymer auf Basis von Polycarboxylatether. Weiterhin wird das Polymer in trockenem Zustand und mit pulverförmiger Konsistenz verarbeitet. Der Einbau der Mischung erfolgt im Kalteinbau. Zunächst wird die Gesteinskörnung mit dem Additiv gemischt und dann das Bindemittel zugegeben. Die Mischung der Bestandteile erfolgt im heißen Zustand, wohingegen der Einbau im Kalteinbau erfolgt.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.
With regard to the construction of the soil cover, a distinction is made between the so-called "bonded construction" and the "unbound construction method". In the unbound design, 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.
In the bonded construction, 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. However, the plaster ceiling in this case is almost impermeable to water.
The closest prior art is the
The
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.
Der Einbau der Mischung im Kalteinbau weist erhebliche Vorteile auf, da aufwendige Maßnahmen zum Erhitzen und zum Halten der notwendigen Temperatur für die Verarbeitung der Mischung nicht erforderlich sind, wie dies zum Beispiel beim Heißeinbau erforderlich ist. Bei dem aus dem Straßenbau bekannten Heißeinbau wird das Bitumen auf etwa 100°C bis 150°C, jedoch nicht mehr als 170°C erhitzt, um eine verarbeitbare Fluidität des Bindemittels zu erreichen. Unter einem Kalteinbau wird hingegen die Verarbeitung und der Einbau in einem Temperaturbereich von 0 °C bis 80 °C vorzugsweise bei Umgebungstemperatur verstanden.The incorporation of the mixture in cold installation has considerable advantages, since complex measures for heating and maintaining the necessary temperature for the processing of the mixture are not required, as required for example in hot installation. In the hot installation known from the road construction, the bitumen is heated to about 100 ° C to 150 ° C, but not more than 170 ° C, in order to achieve a processable fluidity of the binder. By contrast, a cold incorporation means processing and installation in a temperature range from 0 ° C. to 80 ° C., preferably at ambient temperature.
Die erfindungsgemäße Erdreichabdeckung hat weiterhin insbesondere Vorteil, dass das anfallende Niederschlagswasser im Vergleich zur ungebundenen Bauweise nur sehr geringfügig in die Tragkonstruktion der Erdreichabdeckung eindringen kann. Auf diese Weise werden die Anwendungsmöglichkeiten für Erdreichabdeckungen aus Basis von Pflastersteinen erweitert. Das System verhält sich durch das Bindemittel Bitumen wie eine Erdreichabdeckung in elastischer Bauweise.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.
Im Unterschied beispielsweise zu zementgebundenen Pflasterbauweisen sind durch die erfindungsgemäße Lösung Spannungsrisse vermeidbar, die bei zementgebundenen Pflasterbauweisen eine wasserdurchlässige Tragschicht unbedingt erforderlich machen, weil sonst in die Konstruktion eindringendes Niederschlagswasser, insbesondere bei Frostbeanspruchung, zu Schäden führt.In contrast, for example, to cement-bonded pavement constructions stress cracks are avoided by the solution according to the invention, which make a water-permeable base layer necessarily required for cement-based pavement construction, otherwise precipitation into the structure penetrating rain, especially in frost, leads to damage.
Fugen zwischen den Formsteinen können mit einem Fugenfüllmaterial aus einer Gesteinskörnung verfüllt sein, oder mit einem Fugenfüllmaterial aus einer Mischung aus einer Gesteinskörnung mit dem Additiv und einem Bindemittel.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.
Durch die Bindung der Gesteinskörnung mit dem Bitumen wird eine Immobilisierung vor allem der Feinanteile der Gesteinskörnung bewirkt. Die bitumengebundene Gesteinskörnung ist im System insgesamt weniger durch Belastung beansprucht als übliche ungebundene Gesteinskörnung.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.
Ein erfindungsgemäßes Verfahren weist die Maßnahmen des Anspruchs 7 auf. Es ist demnach mit anderen Worten vorgesehen, dass für das Pflasterbett ein kalt herzustellendes Baustoffgemisch aus einer Gesteinskörnung und einem Additiv sowie einem Bindemittel hergestellt wird und dass die Verarbeitung der Mischung im Kalteinbau erfolgt und dass die Pflasterung bzw. die Formsteine (unmittelbar) auf dem Pflasterbett verlegt werden, welches (unmittelbar) auf eine Tragschicht aufgebracht wird. Als Additiv kommt eine Mischung aus einem Polymer mit Quarzsand zum Einsatz. Von besonderer Bedeutung ist auch die Mischreihenfolge, nämlich zunächst eine Vermischung der Gesteinskörnung mit dem Additiv und danach die Zugabe von Bitumen als Bindemittel.An inventive method comprises the measures of claim 7. In other words, it is provided that for the paving bed 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. Of particular importance is also the mixing order, namely first a mixing of the aggregate with the additive and then the addition of bitumen as a binder.
Vorzugsweise wird das Pflasterbett überhöht eingebaut, sodass nach dem Verdichten des Pflasterbetts die Erdreichabdeckung die vorgesehene Höhe ausweist.Preferably, the paving bed is installed over-inflated so that after compaction of the paving bed the soil cover identifies the intended height.
Vorzugsweise weist der Quarzsand eine Körnung von 0,1 bis 2,0 mm auf, insbesondere von 0,1 bis 1,0 mm.Preferably, the quartz sand has a grain size of 0.1 to 2.0 mm, in particular from 0.1 to 1.0 mm.
Gemäß einer bevorzugten Ausführungsform ist vorgesehen, dass der Quarzsand eine mittlere Korngröße von 0,27 bis 0,79 mm aufweist.According to a preferred embodiment, it is provided that the quartz sand has an average particle size of 0.27 to 0.79 mm.
Vorzugsweise handelt es sich bei dem Bindemittel um Bitumen.Preferably, the binder is bitumen.
Vorzugsweise weist das Polymer einen Anteil von 0,05 bis 0,3 Gew.-% des Bindemittelgehalts auf. Um eine gleichmäßige Durchmischung zu erreichen ist das Polymer mit mindestens 450 g Quarzsand zu vermischen.Preferably, the polymer has a content of 0.05 to 0.3 wt .-% of the binder content. In order to achieve a uniform mixing, the polymer must be mixed with at least 450 g of quartz sand.
