Asphalt mixture and preparation method thereof
The invention discloses an asphalt mixture and a preparation method thereof, and particularly relates to an anti-track and anti-upheaval asphalt mixture and a preparation method thereof. The asphalt mixture comprises the following components in percentage by weight: 4.0-6.0% of special road oil asphalt, 1.0-3.0% of cement, 1.0-3.0% of mineral powder and 88.0-94.0% of aggregates. The preparation method comprises the following steps: (1) a stirring kettle and the aggregates are heated to reach 130-180 DEG C for standby, and the special road oil asphalt is heated to a melted state for standby; (2) the aggregates, the cement and the mineral powder are added into the stirring kettle simultaneously and are uniformly stirred; (3) the special road oil asphalt is added into the stirring kettle and is uniformly stirred and mixed with the aggregated, the cement and the mineral powder which are uniformly mixed in the stirring kettle in advance to obtain the asphalt mixture. Due to the fact that the special road oil asphalt is used for the asphalt mixture, the track dynamic stability of the mixture is substantially improved, the anti-track performance of an asphalt road surface can be obviously improved, and the asphalt mixture is particularly suitable for asphalt roads with heavy traffic load and asphalt roads where tracks are likely to occur in high-temperature areas of the southern area of China.
