Title (EN) POLYMER-MODIFIED ASPHALT COMPOSITION
(FR) COMPOSITION D'ASPHALTE MODIFIÉ PAR UN POLYMÈRE
(JA) ポリマー改質アスファルト組成物
Abstract:
(EN) In order to provide a polymer-modified asphalt composition that exhibits both a workability-improving effect and an increased strength and increased durability on a paved roadway, the polymer-modified asphalt composition is characterized by containing, in wt%, 93.0 to 96.7% base asphalt, 3 to 5% SBS, and 0.3 to 2.0% saturated fatty acids having 12 to 22 carbons, and is further characterized in that the base asphalt contains at least one of straight asphalt, propane-deasphalted asphalt, and an aromatic heavy mineral oil.
(FR) Afin d'obtenir une composition d'asphalte modifié par un polymère qui présente à la fois un effet d'amélioration de la maniabilité et une résistance accrue et une durabilité accrue sur une route pavée, la composition d'asphalte modifié par un polymère est caractérisée en ce qu'elle contient, en % en poids, 93,0 à 96,7 % d'asphalte de base, 3 à 5 % de SBS et 0,3 à 2,0 % d'acides gras saturés comprenant 12 à 22 atomes de carbone et est en outre caractérisée en ce que l'asphalte de base contient au moins l'un parmi l'asphalte pur, l'asphalte désasphalté au propane et une huile minérale lourde aromatique.
(JA) 舗装後の道路の高強度化及び高耐久化と、施工性改善効果の両立を図ることが可能なポリマー改質アスファルト組成物を提供するために、何れも重量%で、ベースアスファルト:93.0~96.7%、SBS:3~5%、炭素数12~22の飽和脂肪酸:0.3~2.0%を含有し、ベースアスファルトは、ストレートアスファルト、プロパン脱瀝アスファルト、芳香族系重質鉱油のいずれか一つ以上を含有することを特徴とする。
