AC type airport asphalt mixture mix proportion design method based on high-temperature rutting resistance
The invention discloses an AC type airport asphalt mixture mix proportion design method based on high-temperature rutting resistance, and relates to an AC type airport asphalt mixture mix proportion design method. The invention aims to solve the problem that the existing design method cannot specifically avoid rut damage on the pavement through the mix proportion design of the asphalt mixture. The method comprises the following steps: 1, selecting raw materials; step 2, mineral aggregate gradation design; step 3, determining the optimal gradation; step 4, selecting the amount of test asphalt; 5, calculating the optimal asphalt dosage; step 6, testing the optimal asphalt dosage; and step 7, performance verification. The high-temperature compression strength adopted by the method can reflect the high-temperature performance of the asphalt mixture, the rutting resistance of the pavement structure is improved in a targeted manner in the mix proportion design stage, and the designed asphalt mixture does not need to be subjected to high-temperature performance inspection in the later stage, so that the engineering efficiency is improved. The AC type airport asphalt mixture mix proportion design method based on high-temperature rutting resistance can be obtained.
