Description

Bitumenbahnen sind gemäß DIN 55 946 Bahnen mit Trägereinlage, z.B. Rohfilz, Glasvlies oder -gewebe, Jutegewebe, Chemiefaser­vliese oder -gewebe, die entweder nur mit Bitumentränkmasse ge­tränkt oder zusätzlich auf beiden Seiten mit Deckschichten aus Bitumendeckmassen versehen und mit mineralischen Stoffen be­streut sein kann.According to DIN 55 946, bitumen membranes are membranes with a carrier insert, e.g. Raw felt, glass fleece or fabric, jute fabric, man-made fiber fleece or fabric, which either only soaked with bitumen impregnating compound or additionally provided with cover layers of bituminous covering compound on both sides and sprinkled with mineral substances.

Das Bitumen selbst ist nach DIN 55 946 ein bei der Aufarbeitung geeigneter Erdöle gewonnenes schwer flüchtiges, dunkelfarbiges Gemisch verschiedener organischer Substanzen, deren elasto­viskoses Verhalten sich mit der Temperatur ändert. Die für Bitumen typischen Eigenschaften beruhen auf einem kolloidalen System, in dem eine Phase (Asphaltene und Erdölharze) in einer zusammenhängenden (kohärenten) Phase aus hochsiedenden Ölen (Maltenen) in stabiler Verteilung vorliegt. Die Asphaltene und Erdölharze sind keine einheitliche Stoffgruppe. Sie sind die höhermolekularen Anteile im Bitumen und lassen sich durch ge­eignete Lösemittel trennen.
Zu den Bitumen im weitesten Sinne sind auch die in geologischen Zeiträumen aus Erdölen gebildeten Bitumenanteile von Naturas­phalten zu rechnen.
Derartige Bitumen werden im angelsächsischen Sprachraum (vor­allem USA) als Asphalt bezeichnet.According to DIN 55 946, the bitumen itself is a semi-volatile, dark-colored mixture of various organic substances obtained during the processing of suitable petroleum, whose elastoviscous behavior changes with temperature. The typical properties for bitumen are based on a colloidal system in which a phase (asphaltenes and petroleum resins) is present in a coherent (coherent) phase consisting of high-boiling oils (maltenes) in a stable distribution. The asphaltenes and petroleum resins are not a uniform group of substances. You are the higher molecular weight parts in the bitumen and can be separated by suitable solvents.
The bitumen in the broadest sense also includes the bitumen portions of natural asphalt formed from petroleum in geological periods.
Bitumen of this type is referred to as asphalt in the Anglo-Saxon language area (especially the USA).

Nach DIN 55 946 wird Bitumen von Asphalt unterschieden. So ist Asphalt ein natürlich vorkommendes oder technisch hergestelltes Gemisch aus Bitumen oder bitumenhaltigen Bindemittel und Mine­ralstoffen sowie gegebenenfalls weiteren Zuschlägen und/oder Zusätzen.According to DIN 55 946, bitumen is distinguished from asphalt. For example, asphalt is a naturally occurring or technically produced mixture of bitumen or bituminous binders and minerals as well as, if necessary, further aggregates and / or additives.

Es ist bekannt, Bitumenmischungen für die Dachindustrie, die neben dem Bitumen neutralisierte sulfonierte Polymere und Füll­stoffe enthalten, herzustellen (vgl. US-PS 4 371 641). Der­artige Bitumenmischungen haben den Nachteil, daß durch den Ge­halt an Polymersulfonaten zum einen die Wasserdampfdurchlässig­keit erhöht und zum anderen das Elastizitätsvermögen vermindert wird.It is known to produce bitumen mixtures for the roofing industry which, in addition to the bitumen, contain neutralized sulfonated polymers and fillers (cf. US Pat. No. 4,371,641). Bitumen mixtures of this type have the disadvantage that the content of polymer sulfonates on the one hand increases the water vapor permeability and on the other hand reduces the elasticity.
