The invention provides a method for detecting the flying disease of a drainage asphalt pavement. The method comprises the following steps: S1, acquiring the average structural depth of a wheel track tape and a reference average structural depth; S2, acquiring a structural depth index according to the average structural depth of the wheel track tape and the reference average structural depth; and S3, determining whether flying occurs on the pavement according to the structural depth index. Since whether the pavement has the flying disease is determined according to the structural depth index, effective flying disease detection of the pavement on site is realized; on-site operation is simple, and guidance is provided for determination of the maintenance time of the drainage asphalt pavement;and through proper maintenance measures, the service life of the drainage asphalt pavement is prolonged, and the functions such as drainage, noise reduction and glare prevention of the pavement are given to better play.
