The invention discloses a modified asphalt waterproofing roll for roads and bridges. The modified asphalt waterproofing roll comprises No.70 asphalt, No.10 asphalt, SBS, a polyester tread base, an anti-aging agent, talcum powder and hydrophobic silicon dioxide. The anti-aging agent forms an anti-ultraviolet protective layer on the surface of the waterproof roll in the actual use process, so the waterproof roll can directly reflect irradiated ultraviolet rays, and the waterproof roll cannot be irradiated with the ultraviolet rays, thereby the durability of the waterproof roll is improved, and the internal of the waterproof roll cannot be aged due to the influence of brightness and light rays; and parts of unreflected ultraviolet rays can be directly absorbed by the anti-aging agent, so thatthe rays cannot irradiate the internal of the waterproof roll, the oxidation resistance of the waterproof roll is improved, and the durability and the weather resistance of the waterproof roll are improved, thereby the water
