Asphalt mixture based on desulfurized rubber powder-nano palygorskite-steel slag powder composite modification and preparation method thereof
The invention provides an asphalt mixture based on desulfurized rubber powder-nano palygorskite-steel slag powder composite modification and a preparation method thereof, and aims to solve the technical problem of reducing high and low temperature diseases and water damage of an asphalt pavement while improving the pavement performance of the asphalt mixture. The composite modified asphalt mixture is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 3 to 7 parts of asphalt, 0.05 to 0.10 part of desulfurized rubber powder, 0.06 to 0.18 part of nano palygorskite, 0.03 to 0.07 part of steel slag powder, 0.015 to 0.028 part of improving agent and 0.001 to 0.005 part of coupling agent. The composite modified asphalt mixture provided by the invention has excellent pavement performance, can enhance the high-temperature stability, low-temperature crack resistance, water stability, toughness and ductility of an asphalt pavement, can prolong the service life of the asphalt pavement, and has the advantages of non-toxic and harmless raw materials, wide sources, no pollution in the production process, low price and good economic benefits.
本申请提供一种基于脱硫胶粉‑纳米坡缕石‑钢渣粉复合改性的沥青混合料及其制备方法，旨在解决提升沥青混合料的路用性能的同时减少沥青路面的高低温病害及水损坏的技术问题。该复合改性沥青混合料由以下重量份的原料制成：矿料100份、沥青3～7份、脱硫胶粉0.05～0.10份、纳米坡缕石0.06～0.18份、钢渣粉0.03～0.07份、改善剂0.015～0.028、偶联剂0.001～0.005份。本申请提供的复合改性沥青混合料路用性能优良，可以增强沥青路面高温稳定性、低温抗裂性、水稳定性、韧性及延展性，能延长沥青路面使用寿命，且原料无毒无害，来源广泛，生产过程无污染且价格低廉，具有良好的经济效益。
