description | The invention discloses multifunctional modified asphalt and a preparation method thereof, and belongs to the technical field of road engineering materials. According to the multifunctional modified asphalt prepared by the method disclosed by the invention, the dynamic viscosity at 60 DEG C is greater than 20000 Pa*s, the adhesion with stones at high temperature is strong, and the mixing at 130 DEG C can be achieved. The multifunctional modified asphalt has the advantages of high softening point, high ductility, high elastic recovery capacity, high toughness, aging resistance and the like, andhas the excellent properties that the elastic recovery rate is higher than 95% and the like. According to the method, only a shearing process is needed, and relatively high-viscosity, high-viscosityand high-elasticity modified asphalt needs complex processes such as development and maintenance, so that the purpose of saving the cost is achieved, the production is simple, and manpower idle work and equipment loss are grea |
