Qingchuan rock asphalt-castor oil-rice hull ash composite modified asphalt mixture and preparation method thereof
The invention provides a Qingchuan rock asphalt-castor oil-rice hull ash composite modified asphalt mixture and a preparation method thereof, and aims to solve the technical problem of insufficient pavement performance of the asphalt mixture. The asphalt mixture is prepared from the following raw materials in parts by weight: 100 parts of mineral aggregate, 4-6 parts of asphalt, 0.5-0.75 part of Qingchuan rock asphalt, 0.4-0.6 part of castor oil, 0.45-0.7 part of rice hull ash, 0.35-2 parts of a treating agent and 0.01-0.015 part of a compatibilizer. The asphalt mixture has the advantages of excellent pavement performance, simple preparation process and non-toxic and harmless raw materials, and can enhance the high-temperature stability, low-temperature crack resistance, water stability, toughness and ductility of the asphalt pavement and prolong the service life of the asphalt pavement.
本申请提供一种由青川岩沥青‑蓖麻油‑稻壳灰复合改性的沥青混合料及其制备方法，旨在解决沥青混合料的路用性能不足技术问题。该沥青混合料由以下重量份的原料制成：矿料100份，沥青4～6份，青川岩沥青0.5～0.75份，蓖麻油0.4～0.6份，稻壳灰0.45～0.7份，处理剂0.35～2份，增容剂0.01～0.015份。该沥青混合料路用性能优良，制备工艺简单、原料无毒无害，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，延长沥青路面使用寿命。
