Title (EN) METHODS AND COMPOSITIONS FOR RECYCLED ASPHALT SHINGLES MATERIAL
(FR) PROCÉDÉS ET COMPOSITIONS POUR MATÉRIAU DE BARDEAUX D'ASPHALTE RECYCLÉ
Abstract:
(EN) Certain aspects of the present invention are drawn recycled asphalt shingles-modified asphalt binder blends, mixes, and pavements, especially those comprising a mineral acid. Recycled asphalt shingles material may come from manufacturer asphalt shingle waste or from consumer asphalt shingle waste. It has been discovered that addition of a mineral acid significantly improves various rheological properties. Methods of making such asphalt binders, mixes, and pavements and their use are also disclosed.
(FR) Certains aspects de la présente invention sont des mélanges et des chaussées de couche de liaison d'asphalte à bardeaux modifiés et à asphalte recyclée, en particulier ceux comprenant un acide minéral. Le matériau de bardeaux d'asphalte recyclé peut provenir des déchets de bardeaux d'asphalte du fabricant ou des déchets de bardeaux d'asphalte du consommateur. On a découvert que l'ajout d'un acide minéral améliore significativement diverses propriétés rhéologiques. La présente invention concerne également des procédés de fabrication de mélanges et de chaussées d'asphalte et leur utilisation.
