Referring to fig. 1, the number of the modified asphalt layers 21 is two, and the two modified asphalt layers 21 are symmetrical with respect to the base ply 11. Modified asphalt layer 21 can adopt APP modified asphalt material to make, and APP modified asphalt material is with atactic polypropylene as the material that modifier and asphalt material made jointly, and two modified asphalt layers 21 are located the left and right sides of child basic unit 11 respectively to be connected with the fixed surface of child basic unit 11, the connected mode can bond, and modified asphalt layer 21 is that modified asphalt of atactic polypropylene coats and forms on the surface of child basic unit 11.

Referring to fig. 1, the number of the reinforcing layers 31 is two, the two reinforcing layers 31 are bilaterally symmetric with respect to the base tire layer 11, the reinforcing layers 31 may be formed on the surface of the modified asphalt layer 21 remote from the base tire layer 11 by using a dip-coating of a cellulose asphalt and a fiber web, and the reinforcing layers 31 can increase the strength of the modified asphalt layer 21. The strength of the whole waterproof coiled material is increased, and the anti-cracking performance is higher.
