Title: (DE) SCHNELL TROCKNENDE ASPHALTZUSAMMENSETZUNGEN MIT VERBESSERTER LEISTUNG BEI GERINGEREM ASPHALTRÜCKSTAND
(EN) FAST DRYING ASPHALT COMPOSITIONS WITH IMPROVED PERFORMANCE AT LOWER ASPHALT RESIDUE
(FR) COMPOSITIONS D'ASPHALTE À SÉCHAGE RAPIDE DOUÉE D'UNE PERFORMANCE AMÉLIORÉE À DES TENEURS EN RÉSIDUS ASPHALTIQUES INFÉRIEURES
Abstract:
(EN) Disclosed herein are asphalt compositions. In some embodiments, the asphalt compositions can include asphalt, a polymer, and a basic salt such as aluminum sulfate. In some embodiments, the asphalt compositions can include asphalt, a polymer, and an inorganic acid such as phosphoric acid. The asphalt compositions can include asphalt in an amount of from 50 wt% to 99.9 wt%, based on the weight of the asphalt composition. In some embodiments, the asphalt compositions can include a styrene-butadiene copolymer in an amount of from 0.05 wt% to 10 wt%, based on the weight of the asphalt composition. The basic salt can be present in an amount of from 0.01 wt% to 5 wt%, based on the weight of the asphalt compositions. The acid can be present in an amount of from 0.005 wt% to 0.1 wt%, based on the weight of the asphalt compositions. Methods of making and using the asphalt compositions are also disclosed.
(FR) L'invention concerne des compositions d'asphalte. Dans certains modes de réalisation, les compositions d'asphalte peuvent comprendre de l'asphalte, un polymère et un sel basique tel que le sulfate d'aluminium. Dans d'autres, les compositions d'asphalte peuvent comprendre de l'asphalte, un polymère et un acide inorganique tel que l'acide phosphorique. Les compositions d'asphalte peuvent comprendre de l'asphalte en une quantité de 50 à 99,9 % en poids, sur la base du poids de la composition d'asphalte. Dans certains modes de réalisation, les compositions d'asphalte peuvent comprendre un copolymère de styrène-butadiène en une quantité de 0,05 à 10 % en poids, sur la base du poids de la composition d'asphalte. Le sel basique peut être présent en une quantité de 0,01 à 5 % en poids, et l'acide en une quantité de 0,005 à 0,1 % en poids, sur la base du poids des compositions d'asphalte. Des procédés de préparation et d'utilisation des compositions d'asphalte sont en outre décrits.
