ASPHALT MODIFIER
To provide an asphalt modifier that has excellent mixability and can achieve excellent rutting resistance of asphalt pavement regardless of pre-addition or post-addition of polyester, an asphalt composition, an asphalt mixture and a method for producing the same, and a method for paving a road.SOLUTION: An asphalt modifier comprises a constitutional unit derived from an alcohol component (a1) and a constitutional unit derived from a carboxylic acid component (a2). The carboxylic acid component (a2) comprises a crystalline polyester (A) comprising a C2-6 linear saturated aliphatic dicarboxylic acid.SELECTED DRAWING: None
【課題】ポリエステルの先添加でも後添加でもアスファルト舗装の優れた耐わだち掘れ性等を達成できる、混合性に優れたアスファルト改質剤、アスファルト組成物、アスファルト混合物及びその製造方法、並びに道路舗装方法の提供。【解決手段】アルコール成分（ａ１）由来の構成単位及びカルボン酸成分（ａ２）由来の構成単位を含み、該カルボン酸成分（ａ２）が炭素数２以上６以下の直鎖飽和脂肪族ジカルボン酸を含む結晶性ポリエステル（Ａ）を含むアスファルト改質剤。【選択図】なし
