AGE RESISTANT BITUMINOUS COMPOSITION |
| 摘要 |
<p>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.</p> |
