High-performance modified asphalt mixture and preparation method thereof
The invention relates to the technical field of modified asphalt, in particular to a high-performance modified asphalt mixture and a preparation method thereof. The invention relates to a high-performance modified asphalt mixture, which is prepared from the following raw materials in parts by mass: 5.0 to 7.5 parts of modified asphalt, 0.40 to 0.80 part of SBS (Styrene Butadiene Styrene) grafted maleic anhydride, 0.15 to 0.30 part of polycaprolactone, 0.30 to 0.75 part of rubber oil, 0.045 to 0.105 part of dioctyl adipate, 0.01 to 0.015 part of stabilizer, 0.25 to 0.45 part of polyester fiber, 79.5 to 89.0 parts of aggregate and 7.0 to 12.5 parts of filler. The high-temperature stability and the water stability of the pavement can be improved, the pavement performance and the anti-fatigue performance are good, the anti-fatigue performance of the asphalt pavement under the vehicle load effect can be remarkably improved, and the service life of the pavement is prolonged.
