Description

Verfahren -zur Aufrauhung von Asphaltdecken Asphaltdecken nehmen unter der Einwirkung starken Verkehrs im Laufe der Zeit eine gewisse Glätte an, deren Beseitigung im Interesse der Sicherheit des- Verkehrs erstrabensrovert ist. Es 'sind zahlreiche Vor.. schläge gemacht worden, um durch mechanische Aufrauhung oder. durch Bestreuen der Oberfläche diesen Mangel zu beseitigen. Praktisch haben diese Vorschläge zu keinem Ergebnis geführt.Procedure -for roughening asphalt pavements asphalt pavements take the effect of heavy traffic over time a certain smoothness, whose Elimination in the interests of the safety of traffic is a first-time rovert. There are Numerous suggestions have been made to make up by mechanical roughening or. by Sprinkle the surface to eliminate this deficiency. In practice, these have suggestions led to no result.

Das Verfahren nach der Erfindung ist ein Ätzverfahren. Es geht von der Voraussetzung. aus, daß es nur- dadurch gelingt, der Glätte dies Asphalts wirksam zu begegnen, daB die eigentliche Oberfläche des Asphalts in ihrer Struktur verändert wird. Dies wird erfindungsgemäß durch. eine chemische Einwirkung auf die Asphaltoberfläche. erreicht. Der Asphaltbelag besteht häufig zu etwa 9o % aus kohlensaurem Falk. Die Anätzung der Oberfläche kann daher durch zahlreiche saure oder salzartige Lösungen bewirkt werden, z. B. durch verdünnte Salzsäure oder salzsäurehaltige Gemische, durch verdünnte Schwefelsäure, saure Salze u. dgl. m. Man begrenzt die Menge der sauren Flüssigkeit derart, daß die gewünschte Ätzwirkung eintritt und die saure Flüssigkeit hierbei restlos verbraucht wird. Die Oberfläche des Asphalts wird dadurch aufgerauht, ohne die Decke selbst zu gefährden.The method according to the invention is an etching process. It goes from the requirement. from the fact that it is only in this way that the smoothness of this asphalt is effective to counteract that the actual surface of the asphalt changes in its structure will. This is done according to the invention. chemical action on the asphalt surface. achieved. The asphalt surface often consists of about 90% carbonate of falcon. the The surface can therefore be etched with numerous acidic or salt-like solutions be effected, e.g. B. by dilute hydrochloric acid or mixtures containing hydrochloric acid, by dilute sulfuric acid, acidic salts and the like. The amount of the acidic liquid in such a way that the desired etching effect occurs and the acidic Liquid is completely used up in this process. The surface of the asphalt is thereby roughened without endangering the ceiling itself.

Das Verfahren kann dadurch noch wirksamer gestaltet wenden, daß in die durch Ätzung aufgerauhte Oberfläche ein indifferentes -Material, z. B. Sand, .Splitt o. dgl., eingestreut wirrt. Dieses feinkörnige Material pneßt sich unter der Einwirkung des Verkehrs in,die Ätzfugen der Oberfläche ein und sorgt dafür, daß die durch Ätzung erzielte Rauhigkeit bestehenbleibt. Auch kann man vor Aufbringung dies Sandes oder Splitts die geätzte Asphaltoberfläche mit einem Anstrich aus klebefähigem Bitumen o. dgl. in an sich be-1zannter Weise versehen..The process can be made even more effective by the fact that in the surface roughened by etching an indifferent material, e.g. B. sand, .Split or the like, interspersed tangled. This fine-grained material pneeps under the effects of traffic in, the etched joints of the surface and ensures that the roughness achieved by etching remains. You can also do this before applying This sand or grit the etched asphalt surface with a coat of adhesive Bitumen or the like provided in a manner known per se ..
