Title:
架橋クラムラバーを使用する改質アスファルトバインダ材料および改質アスファルトバインダを製造する方法
Document Type and Number:
Japanese Patent JP2008540739
Kind Code:
A
Abstract:
Bituminous asphalt binder materials which are modified by the addition of crumb rubber or ground tire rubber and a cross-linking agent are described. In addition, methods are provided for producing a modified asphalt binder containing crumb rubber or ground tire rubber and a cross-linking agent. The modified asphalt binders comprise neat asphalt, crumb rubber, one or more acids and a cross-linking agent. Optionally, the modified asphalt binder may include one or more polymer additives. The crumb rubber may be obtained from recycled truck and/or automobile tires. The addition of crumb rubber in asphalt binders can improve the consistency and properties of the asphalt binders at high and low temperatures. In particular, the modified asphalt binders of the present invention exhibit improved elastic behavior, resulting in improved performance of roads or other surfaces paved using the modified asphalt binder. Road resistance to permanent deformation, fatigue cracking and thermal cracking is improved by use of the modified asphalt binder.
