Preparation method of high-performance asphalt mixture
The invention discloses a preparation method of a high-performance asphalt mixture. The preparation method comprises the following steps: S1, setting the heating temperature of a stirring bin to be 180 DEG C; s2, putting a screened coarse and a fine aggregate in and stirring for 25-30 seconds, wherein the stirring rotating speed in the stirring process is 35 +/-0.5 r/min, and the vibration frequency is 40 +/-0.5 Hz; s3, adding asphalt, stirring for 25-30 seconds, wherein the stirring rotating speed in the stirring process is 35 +/-0.5 r/min, and the vibration frequency is 40 +/-0.5 Hz; s4, adding mineral powder, stirring for 25-30 seconds, wherein the stirring rotating speed in the stirring process is 35 +/-0.5 r/min, and the vibration frequency is 40 +/-0.5 Hz; and S5, discharging and preserving heat for later use. According to the preparation method disclosed by the invention, the asphalt can be fully utilized in the asphalt mixture, the loss of the asphalt mixture is reduced, and meanwhile, the pavement performance of the asphalt mixture can be improved.
本发明公开一种高性能沥青混合料的制备方法，包括以下步骤：S1.将搅拌仓加热温度设定为180℃；S2.放入筛分好的粗细集料，并搅拌25秒～30秒，搅拌过程中的搅拌转速为35±0.5r/min，振动频率为40±0.5Hz；S3.加入沥青，并搅拌25秒～30秒，搅拌过程中的搅拌转速为35±0.5r/min，振动频率为40±0.5Hz；S4.加入矿粉，并搅拌25秒～30秒，搅拌过程中的搅拌转速为35±0.5r/min，振动频率为40±0.5Hz；S5.卸料保温备用。本发明的制备方法既能使沥青在沥青混合料中得到充分利用，减少沥青混合料的损失，同时又可以提高沥青混合料的路用性能。
