Abstract
Description
Die Erfindung betrifft einen Gußasphalt nach dem Oberbe griff des Patentanspruchs 1.The invention relates to a mastic asphalt according to the Oberbe handle of claim 1.
Gußasphalt ist ein hohlraumfreies Gemisch aus einem Mine ralgemisch abgestufter Körnung und Bitumen. Das Gesteins gemisch stellt strukturbildendes Material mit Füllern dar, während das Bitumen als Bindemittel dient. Die Konzentra tion des Bindemittels ist bei Gußasphalt so abgestimmt, daß die Hohlräume des Gesteinsgemisches ausgefüllt werden. Gußasphalt ist bei Verarbeitungstemperatur fließfähig, da her muß Gußasphalt im Gegensatz zu Walzasphalt beim Einbau nicht verdichtet werden. Mastic asphalt is a void-free mixture from a mine mixed mix of graded grain and bitumen. The rock mixture represents structure-forming material with fillers, while the bitumen serves as a binder. The concentra tion of the binder is matched with mastic asphalt that the cavities of the rock mix are filled. Mastic asphalt is flowable at processing temperature because In contrast to rolled asphalt, mastic asphalt must be used for paving not be compressed.
Eine wichtige Verwendung findet Gußasphalt als hochver schleißfester Fahrbahnbelag im Straßen- und Industriebau. Das Gesteinsgemisch besteht dabei in der Regel aus Splitt (gebrochenem Hartgestein), Sand und Füllern, wie zum Bei spiel Kalksteinmehl. Ein mit solch einem Gesteinsgemisch hergestellter Gußasphalt besitzt ein spezifisches Gewicht von 2400-2600 kp/m³. Dieses Gewicht kann einen Nach teil bei der Verwendung des Gußasphalts darstellen, zum Beispiel im Hochbau sowie als Belag auftragenden Baukon struktionen, wie zum Beispiel Parkhäusern oder Brücken, bei denen aus statischen Gründen möglichst geringe Auf lasten gefordert sind. Oftmals sind hohe Auflasten zu mindest mit wirtschaftlichen Nachteilen verbunden.Mastic asphalt has an important use as high ver wear-resistant road surface in road and industrial construction. The rock mix usually consists of grit (broken hard rock), sand and fillers, as for example game Limestone Flour. One with such a rock mix Mastic asphalt produced has a specific weight from 2400-2600 kp / m³. This weight can be an after represent part of the use of mastic asphalt to Example in building construction and as a building contract structures, such as parking garages or bridges, where for static reasons the lowest possible loads are required. High loads are often too associated with at least economic disadvantages.
Mischungen aus Bitumen und Blähton, einem Stoff mit rela tiv geringem spezifischem Gewicht, werden zwar im Straßen bau verwendet, dabei handelt es sich aber um Walzasphalt, der das Eindringen von Frost in den Untergrund verhindern soll.Mixtures of bitumen and expanded clay, a substance with rela tiv low specific weight, although in the streets used construction, but this is rolled asphalt, which prevent frost from entering the ground should.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Guß asphalt zur Verfügung zu stellen, der ein geringeres spe zifisches Gewicht als herkömmlicher Gußasphalt hat, wobei die mechanischen Eigenschaften im wesentlichen gleich und die Wärmedämmeigenschaften verbessert sind. The invention is therefore based on the task of a casting to provide asphalt with a lower spe has specific weight than conventional mastic asphalt, whereby the mechanical properties are essentially the same and the thermal insulation properties are improved.
Diese Aufgabe wird durch gattungsgemäßen Gußasphalt gelöst, bei dem das strukturbildende Material vollständig oder teilweise von in partikulärer Form vorliegenden hitzebe ständigen, porösen Stoffen mit einem geringen spezifischen Gewicht gebildet werden.This task is solved by generic mastic asphalt, in which the structure-forming material is completely or partly from heat bees in particulate form permanent, porous materials with a low specific Weight are formed.
Bei diesem erfindungsgemäßen Gußasphalt, der im folgenden als Leichtgußasphalt bezeichnet wird, können die Komponen ten Splitt und Kalksteinmehl ganz oder teilweise durch Zu schläge aus den porösen, hitzebeständigen Stoffen ersetzt werden. Ebenso können die genannten Stoffe anstelle von Teilen des Natur- und Brechsandes verwendet werden.In this mastic asphalt according to the invention, the following the components can be referred to as lightweight asphalt all or part of the chippings and limestone powder by adding blows from the porous, heat-resistant materials replaced will. The substances mentioned can also be used instead of Parts of natural and crushed sand can be used.
Bei den porösen, hitzebeständigen Stoffen kann es sich um natürliche Leichtgesteine wie Bims und Tuff oder um künst liche Leichtzuschläge wie Blähton und Schaumglas in parti kularer Form handeln, oder auch um ähnliche Stoffe mit einer entsprechenden Festigkeit und Hitzebeständigkeit.The porous, heat-resistant fabrics can be natural light rocks such as pumice and tuff or around art Partial light aggregates such as expanded clay and foam glass act in a specific form, or with similar substances appropriate strength and heat resistance.
Blähton ist ein feucht angemachter fetter Ton, der im Drehofen gebrannt wird und durch Wasserverdampfung fein porig ist. Schaumglas ist ein erstarrter Glas-Schaum mit luftdicht geschlossenen Zellen, die mit Gas gefüllt sind. Expanded clay is a moist, moist clay, which in the Rotary kiln is burned and fine by water evaporation is porous. Foam glass is a solidified glass foam with hermetically sealed cells that are filled with gas.
Eine günstige Zusammensetzung für einen erfindungsgemäßen Gußasphalt, bestehend aus Blähton, Sand, Füller und Binde mittel, ist in dem Unteranspruch 3 angegeben.A favorable composition for an inventive Mastic asphalt, consisting of expanded clay, sand, filler and bandage medium, is specified in subclaim 3.
Besonders vorteilhaft wirkt sich bei dem Leichtgußasphalt das im Vergleich zu herkömmlichem Gußasphalt reduzierte spezifische Gewicht aus, das 1200-2000 kp/m³ betragen kann. Ferner ist die Wärmeleitfähigkeit von Leichtguß asphalt geringer als die von herkömmlichem Gußasphalt, sie kann 0,4-0,8 W K-1 m-1 betragen.The reduced weight compared to conventional mastic asphalt, which can be 1200-2000 kp / m³, has a particularly advantageous effect on lightweight mastic asphalt. Furthermore, the thermal conductivity of lightweight asphalt is lower than that of conventional cast asphalt, it can be 0.4-0.8 WK -1 m -1 .
Die mechanischen Eigenschaften entsprechen denen von her kömmlichem Gußasphalt oder sind sogar verbessert. So kann die Zellstruktur der Leichtzuschläge eine verbesserte Schwingungs- und Schalldämmung bewirken. Ferner können im Leichtgußasphalt, ähnlich wie in Holz, Verbindungen mit Nägeln und Schrauben hergestellt werden. Aus diesen Eigen schaften ergeben sich zusätzliche Anwendungsmöglichkeiten für Leichtgußasphalt.The mechanical properties correspond to those from before conventional mastic asphalt or are even improved. So can the cell structure of the light supplements improved Vibration and sound insulation. Furthermore, in Lightweight asphalt, similar to wood, connections with Nails and screws are made. For this own additional application possibilities for lightweight asphalt.
