Ultrahigh-section transverse drainage structure for draining asphalt pavement

The utility model relates to the technical field of road engineering, and discloses an ultrahigh-section transverse drainage structure for draining an asphalt pavement. According to the drainage structure, an old road lower bearing layer and a spliced width lower bearing layer are connected, the included angle between the old road lower bearing layer and the spliced width lower bearing layer is smaller than 180 degrees, and at least one end of the ultrahigh-section transverse drainage structure inclines downwards relative to the horizontal direction. By adjusting the gradient of the gradient section of the ultrahigh section of the middle surface layer, the lower bearing layer of the pavement in the forward driving direction and the lower bearing layer of the pavement in the reverse drivingdirection are each of an arch structure, so that the wide drainage asphalt pavement can drain water rapidly and transversely, zero slope points of the ultrahigh section of the wide drainage asphalt pavement can drain water r
