Zusammenfassung:	The utility model relates to the technical field of pavement drainage, and provides a drainage structure of a drainage asphalt pavement. The drainage ditch comprises an ultrahigh section, a gap type drainage ditch is formed in the edge of the ultrahigh section, the first side, making contact with the ultrahigh section, of the gap type drainage ditch is lower than the road surface set distance of the ultrahigh section, and the second side of the gap type drainage ditch is higher than the road surface set distance of the ultrahigh section. The seam type drainage ditch is arranged on the ultrahigh section of the drainage asphalt pavement, the first side of the seam type drainage ditch in contact with the ultrahigh section is arranged to be lower than the pavement set distance of the ultrahighsection, and the second side of the seam type drainage ditch is arranged to be higher than the pavement set distance of the ultrahigh section. The water permeability of the gap type drainage ditch ismatched with that of an u
