Method for determining amount of asphalt in asphalt mixture based on mechanical property parameters

The invention discloses a method for determining the asphalt amount of an asphalt mixture based on mechanical property parameters. The method comprises the following steps: 1, selecting materials and grading; 2, selecting an asphalt dosage range and values of other influence factors; 3, establishing a correlation model of different mechanical parameters and asphalt consumption within a value range; 4, determining the optimal asphalt dosage through the correlation model; and 5, model performance detection and evaluation. According to the method, the asphalt pavement damage is directly related to the mechanical action of the structural load, so that the asphalt consumption of the asphalt mixture is comprehensively determined on the basis of the optimal values of key mechanical parameters such as strength, modulus and Poisson's ratio; the asphalt dosage determination method provided by the invention is different from a Marshall test determination method based on volume parameters, can quickly and accurately dete
