Carbon fiber rubber modified asphalt mixture and preparation method thereof
The invention discloses a carbon fiber rubber modified asphalt mixture and a preparation method thereof, relates to the technical field of asphalt materials, and solves the problem of low dynamic modulus of a high-content rubber powder modified asphalt mixture in the prior art. The carbon fiber rubber modified asphalt mixture comprises rubber modified asphalt, mineral aggregate and carbon fibers,wherein the mass ratio of the rubber modified asphalt to the mineral aggregate is 4.6-5.6%, and the carbon fibers account for 0.1-0.3% of the total mass of the mixture. According to the technical scheme provided by the invention, the rigidity of the large-mixing-amount rubber powder modified asphalt mixture is effectively improved, the dynamic modulus of the large-mixing-amount rubber powder modified asphalt mixture is improved, and the matching property and the stability of a pavement structure are improved.
本发明公开了一种碳纤维橡胶改性沥青混合料及其制备方法，涉及沥青材料技术领域，解决了现有技术中大掺量胶粉改性沥青混合料动态模量较低的问题。本发明的碳纤维橡胶改性沥青混合料，包括橡胶改性沥青、矿料以及碳纤维，所述的橡胶改性沥青与矿料质量比的百分数为4.6％～5.6％，所述的碳纤维占混合料总质量的0.1～0.3％。本发明提供的技术方案有效地提升了大掺量胶粉改性沥青混合料的刚性，提高了大掺量胶粉改性沥青混合料的动态模量，改善了路面结构的匹配性和稳定性。
