Composite modified asphalt mixture and preparation method thereof
The invention relates to the technical field of modified asphalt, in particular to a composite modified asphalt mixture and a preparation method thereof. The mixture comprises the following componentsin parts by mass: 5-10 parts of modified asphalt, 1.5-5 parts of water-soluble polymer sodium carboxymethyl cellulose, 1-5 parts of a stabilizer, 1-5 parts of a curing agent, 1-5 parts of a shrinkagereducing agent and 100-200 parts of a stone material. According to the composite modified asphalt mixture and the preparation method thereof, the product structure is stable, and the segregation problem of modified asphalt and stone after mixing in the prior art can be greatly improved.
本发明涉及改性沥青技术领域，特别涉及一种复合改性沥青混合物及其制备方法。其混合物包括以下质量份数的组分：改性沥青5‑10质量份，水溶性高分子羧甲基纤维素钠1.5‑5质量份，稳定剂1‑5质量份，固化剂1‑5质量份，减缩剂1‑5质量份，石料100‑200质量份。本发明的一种复合改性沥青混合物及其制备方法，其产品结构稳定，能够大大改善现有技术下改性沥青与石料混合后的离析问题。
