Dry-process high-viscosity modified asphalt mixture
The invention discloses a dry-process high-viscosity modified asphalt mixture, and belongs to the technical field. The technical problems that the existing high-viscosity high-elasticity modified asphalt is long in storage time and unstable in performance during high-temperature storage are solved. The dry-method high-viscosity modified asphalt mixture provided by the invention is prepared from the following components in parts by mass: 86.7 to 92.6 parts of aggregate, 3 to 8 parts of mineral powder, 0.4 to 0.8 part of high-viscosity modifier and 4.0 to 4.5 parts of asphalt. The high-viscosity and high-elasticity modifier can be placed at normal temperature, can be used at any time and is stable in performance, and a dry-process type high-viscosity modified asphalt mixture prepared from the high-viscosity and high-elasticity modifier is also stable in performance.
本发明公开了一种干法型高粘改性沥青混合料，属于技术领域；解决了现有高粘高弹改性沥青高温存储时，存储时间长且其性能不稳定的技术问题。本发明提供的干法型高粘改性沥青混合料按质量计包括：集料：86.7～92.6份，矿粉：3～8份，高粘改性剂：0.4～0.8份和沥青4.0～4.5份。本发明的高粘高弹改性剂可常温放置，随时可用，性能稳定，由其制备的干法型高粘改性沥青混合料也性能稳定。
