A Preparation Method for High-Performance Asphalt Mixture
Abstract of Descriptions The invention discloses a preparation method for high-performance asphalt mixture, which comprises the following steps: Si. Set the heating temperature of the mixing bin to 180°C; S2. Put in the sieved coarse and fine aggregates, and mix them for 25~30 seconds, the mixing speed during the mixing process is 35+0.5r/min and the vibration frequency is 40+0.5Hz; S3. Add asphalt and mix it for 25~30 seconds, the mixing speed during the mixing process is 350.5r/min, and the vibration frequency is 400.5Hz; S4. Add mineral powder and mix it for 25~30 seconds, the mixing speed during the mixing process is 350.5r/min, and the vibration frequency is 400.5Hz; S5. Discharge and keep warm for later use. The preparation method of the invention can not only make full use of the asphalt in the asphalt mixture, reduce the loss of asphalt mixture, but also improve the pavement performance of asphalt mixture.
