RCA modified asphalt mixture for highway construction and preparation method thereof
The invention relates to the technical field of road engineering, and discloses an RCA modified asphalt mixture for highway construction, the RCA modified asphalt mixture is prepared from mineral aggregate, matrix asphalt and RCA, the content of the matrix asphalt is 3.9-4.3% of the mass of the mineral aggregate, the content of the RCA is 1.0-2.0% of the mass of the mineral aggregate, and the invention also provides a preparation method of the RCA modified asphalt mixture. Compared with the traditional SBS modified asphalt mixture, the RCA modified asphalt mixture prepared by the invention has more excellent high-temperature rut resistance; according to the production process, the RCA is directly mixed with the matrix asphalt and the aggregate by adopting a'dry method 'process, so that the production process is relatively simple; the compatibility of the RCA and the matrix asphalt is good, and the performance of the produced RCA modified asphalt mixture is more stable.
本发明涉及道路工程技术领域，公开了一种公路施工用RCA改性沥青混合料，由矿料、基质沥青和RCA制成，其中基质沥青含量为矿料质量的3.9％～4.3％，RCA含量为矿料质量的1.0％～2.0％，同时还提供其制备方法。与传统的SBS改性沥青混合料相比，本发明制备的RCA改性沥青混合料的高温抗车辙性能更优越；其生产流程是采用“干法”工艺使RCA直接与基质沥青和集料进行拌合，生产流程较简单；RCA与基质沥青相容性好，生产的RCA改性沥青混合料性能更稳定。
