Method for measuring durability of modified asphalt based on cohesive energy

The invention relates to the field of detection methods, in particular to a cohesive energy-based modified asphalt durability determination method, which comprises the following steps: preparing two parts of asphalt to be detected with the same specification as normal test samples, simultaneously carrying out synchronous tensile test on the normal test samples and aging test samples in an experiment group and a parallel experiment group, and recording the test result of each group in the test process, according to the test data, the tension value of a unit time point, the specific tension value and ductility of the corresponding displacement length and the time when the displacement reaches the maximum damage length, supplementing each test data into the coordinate system to obtain a normal test sample tension-displacement curve chart and an aging test sample tension-displacement curve chart in the test group and the parallel test group; the image areas covered by the tension-displacement curve in the experim
