Anti-rutting asphalt mixture and preparation method thereof
The invention discloses an anti-rutting asphalt mixture and a preparation method thereof. The anti-rutting asphalt mixture disclosed by the invention comprises the following components in percentage by weight: 1.0-3.0% of an anti-rutting modifying agent, 4.0-6.0% of petroleum asphalt, 1.0-3.0% of cement, 1.0-3.0% of a mineral powder, and 85.0-93% of aggregates. The preparation method of the anti-rutting asphalt mixture comprises the following steps: heating a stirring kettle and the aggregates to be at a temperature of 125-150 DEG C for standby application, simultaneously adding molten petroleum asphalt, the aggregates, the cement, the mineral powder and anti-rutting modifying agent particles in the stirring kettle, and uniformly stirring the mixture so as to obtain the anti-rutting asphalt mixture. The specially-made anti-rutting modifying agent is added in the anti-rutting asphalt mixture, so that the dynamic rutting stability of a mixture vehicle is greatly improved, the anti-rutting performance of asphalt pavements can be obviously improved, and the anti-rutting asphalt mixture is particularly suitable for asphalt highways with heavy traffics and asphalt highways where rutting is easy to occur in high-temperature regions in the South of China.
