Asphalt mixture with superstrong anti-rutting performance
The invention relates to an asphalt mixture with superstrong anti-rutting performance, and particularly relates to an asphalt mixture which has especially excellent anti-rutting performance at a high temperature, and is especially applicable to the field of heavy-duty traffic. The asphalt mixture comprises aggregate, cement, modified asphalt and an anti-rutting agent, and the aggregate comprises crude aggregate and fine aggregate; and the specifications of the aggregate are respectively 19-26.5mm, 11-19mm, 5-11mm, 3-5mm and 0-3mm, and the ratios of the aggregates and the cement accounting for total mass of the aggregates and cement is 12:33:25:10:18:2. The preparation method of the asphalt mixture comprises the following steps: 1) preparing modified asphalt; 2) mixing the aggregates with cement, and adding the anti-rutting agent; and 3) weighing the modified asphalt obtained in the step 1), which accounts for 4.38% of the mass of the aggregates and the cement, and placing into a mixing cylinder and stirring for 40-45s, to obtain the asphalt mixture with superstrong anti-rutting performance. The water stability and low-temperature performance can meet the requirement of an expressway, and the high-temperature stability performance is especially excellent.
