It will be appreciated that, in this embodiment, at the time of overlapping, the first lap end 610 is on top, the second lap end 620 is on bottom, and the second lap end 620 overlaps the first lap end 610 and is bonded together by a waterproof adhesive.

The bonding base layer extension end 611, the reinforcing layer extension end 612 and the asphalt main body layer extension end 613 are respectively formed by extending the bonding base layer 500, the reinforcing layer 400 and the asphalt main body layer 100 towards the first lap end 610. The metal protective layer extension end 621 and the weather-resistant layer extension end 622 are respectively formed by extending the metal protective layer 300 and the weather-resistant layer 200 toward the second overlapping end 620. Thus, after weatherable layer extended end 622 is lapped over the upper surface of asphalt body layer extended end 613 and bonded together by glue, the properties of the splice are consistent with the body properties. Meanwhile, after splicing is completed, the thickness of the spliced part is consistent with that of the main body, and the problem of uneven thickness at the spliced part is solved.
