Title (EN) BITUMEN COMPOSITIONS AND A PROCESS FOR THEIR PREPARATION
(FR) COMPOSITIONS DE BITUME ET LEUR PROCEDE DE PREPARATION
Abstract: front page image
(EN)The invention provides a process for preparing a bitumen composition comprising blowing a mixture with an oxygen-containing gas which mixture comprises a bitumen having a penetration of at least 300 dmm (as measured by ASTM D 5 at 25 °C) and a thermoplastic rubber which is present in an amount of less than 1 wt.%, based on total mixture; bitumen compositions obtainable by such process; and the use of such bitumen compositions in industrial applications.
(FR)L'invention concerne un procédé de préparation d'une composition de bitume, consistant à souffler un mélange à l'aide d'un gaz contenant de l'oxygène, ce mélange comprenant un bitume possédant une pénétration d'au moins 300 dmm (selon les mesures ASTM D 5 à 25 °C), ainsi qu'un caoutchouc thermoplastique présent en une quantité pondérale inférieure à 1 % du poids du mélange total. On décrit également des compositions de bitume que l'on peut obtenir à l'aide d'un tel procédé, ainsi que l'utilisation de ces compositions de bitume dans des applications industrielles.
