| description | Thermally stable built-up roofing asphalt ("BURA") composition comprising a paving grade asphalt is disclosed. The paving grade asphalt has been over-blown to a first softening point and an additive is included in an amount to achieve a second softening point. The additive comprises at least at least one ester. The BURA composition is thermally stable at processing temperatures of at least 450 °F.
Cette invention concerne une composition d'étanchéité multicouche par feutre bitumé ("BURA") thermiquement stable comprenant un asphalte de qualité pavage. L'asphalte de qualité pavage a été sur-oxydé jusqu'à un premier point de ramollissement et un additif est inclus en une quantité permettant d'obtenir un second point de ramollissement. L'additif comprend au moins au moins un ester. La composition BURA est thermiquement stable à des températures de traitement d'au moins 450 °F. |
