Abstract
(DE)
Es wird ein bei Normaltemperatur rieselfähiges und bei einer Temperatur oberhalb 130 °C schmelzendes Granulat aus einem polymeren Material und Gummi oder Bitumen und Gummi hergestellt, welches einen Anteil an Gummi von 50 bis 95 Gew.-% aufweist. Das Granulat dient als Masterbatch für die Einbringung des Gummianteils in Gummiasphalt.
(EN)
The invention concerns granulates which are pourable at standard temperature and melt at temperatures above 130 °C. The granulates are produced from a polymer material and rubber or bitumen and rubber comprising between 50 and 95 wt.% rubber. The granulates are used as a master batch for introducing the rubber portion into rubber-asphalt.
(FR)
L'invention concerne des granulés coulants à température normale et fondants à une température supérieure à 130 °C, comprenant un matériau polymère et du caoutchouc ou bien du bitume et du caoutchouc. Ces granulés contiennent entre 50 et 95 % en poids de caoutchouc et s'utilisent comme mélange maître pour introduire la proportion de caoutchouc dans l'asphalte à base de caoutchouc.
