Warm-mix asphalt mixture and preparation method thereof
The invention discloses a warm-mix asphalt mixture. The warm-mix asphalt mixture comprises the following components in percentage by mass: 4.0-6.0% of warm-mix asphalt, 1.0-3.0% of mineral powder and 91.0-95.0% of aggregate; the warm-mix asphalt is prepared by the warm-mix agent. The warm-mix agent is prepared by the high polymer alkane, halogen, aromatic oil and catalyst. The dosage of the halogen is 0.3-0.5 times of the mole number of the high polymer alkane. The weight ratio of the high polymer alkane and the aromatic oil is (1-7):(7-1). The dosage of the catalyst is 0.3-0.9% of the content of the arene in the aromatic oil. The mixing and forming temperature can be reduced for the warm-mix asphalt mixture, the harmful gas generation amount is reduced, the warm-mix asphalt mixture is friendly to the environment, and the high and low temperature performance of the asphalt mixture can be improved.
