Composition for modifying asphalt, modified asphalt, production methods of the composition and modified asphalt, and asphalt mixture
The invention relates to a composition for modifying asphalt, modified asphalt, production methods of the composition and the modified asphalt, and an asphalt mixture. The composition for modifying asphalt comprises (A) natural asphalt, (B) an asphalt softening agent, (C) a cross-linking agent and (D) a coupling agent; relative to the total mass of the natural asphalt (A), the content of the asphalt softening agent (B) is 15-50% by mass, the content of the cross-linking agent (C) is 0.5-10% by mass, and the content of the coupling agent (D) is 1-6% by mass; and the size of mineral particles in the natural asphalt (A) is less than 800 meshes. The modified asphalt is a cured product of a mixture of the composition for modifying asphalt and matrix asphalt. The asphalt mixture provided by the invention contains the modified asphalt provided by the invention.
本发明涉及一种沥青改性用组合物、改性沥青和它们的制造方法以及沥青混合料。本发明的沥青改性用组合物包括：(A)天然沥青，(B)沥青软化剂，(C)交联剂，(D)偶联剂；相对于所述(A)天然沥青的总质量，所述(B)沥青软化剂的含量为15～50质量％，所述(C)交联剂的含量为0.5～10质量％，所述(D)偶联剂的含量为1～6质量％；所述(A)天然沥青中的矿物质颗粒的尺寸为小于800目。本发明的改性沥青为本发明的沥青改性用组合物与基质沥青的混合物的固化产物。本发明的沥青混合料包含本发明的改性沥青。
