Title (EN) AGE RESISTANT BITUMINOUS COMPOSITION
(FR) COMPOSITION BITUMINEUSE RESISTANTE AU VIEILLISSEMENT
Abstract: front page image
(EN)The invention relates to a bituminous composition containing: (a) at least one age-sensitive bitumen; and (b) at least one paraffin. The paraffin adjunction in a concentration of between 0.5 and 5.0 wt % imparts a better age-resistance to the bituminous composition, with measures showing that the variation of the ball and ring softening temperature of the bituminous composition after RTFOT of the bitumen with the additive is lower than the variation the ball and ring softening temperature of said bitumen alone after RTFOT.
(FR)L'invention concerne une composition bitumineuse comprenant : (a) au moins un bitume sensible au vieillissement, et (b) au moins une paraffine. L'additivation en paraffine, à une teneur comprise entre 0,5 et 5% en poids, confère à la composition bitumineuse une meilleure résistance au vieillissement, mesurée par une variation de la température de ramollissement bille et anneau de la composition bitumineuse après RTFOT du bitume additivé inférieure à la variation de la température de ramollissement bille et anneau dudit bitume seul après RTFOT.
