The invention provides a large-particle-size graded broken stone base segregation detection method based on a Bailey method, and belongs to the technical field of pavement base detection, and the method comprises the following steps: step 1, setting fractal dimension as a judgment index; step 2, determining a segmentation range of the crushed stone material by using a Bailey method; and step 3, detecting the segregation condition of the crushed stone material. According to the method, physical characteristics of all grades of materials are considered, key sieve pores are determined according to a Bailey method, a grading curve is subjected to segmented inspection, and the grading dispersion degree of coarse and fine aggregates is comprehensively evaluated, so that separation of the large-particle-size graded broken stone base is well controlled and prevented, and the method has important significance in preventing early-stage diseases of a pavement and prolonging the service life of the pavement. 本发明提供基于贝雷法的大
