The invention discloses a color-changeable asphalt waterproof coiled material and a preparation method thereof. The color-changeable asphalt waterproof coiled material comprises a waterproof core layer and a color-changeable isolating membrane arranged on the surface of at least one side of the waterproof core layer, the color-changeable isolating membrane comprises a color-changing agent, the color-changing agent comprises a color-changeable material which can change color and generate gas at a color-changing temperature, and the color-changing temperature is 180-350 DEG C. When the asphalt waterproof coiled material is subjected to fire baking construction, the color changing agent in the isolating membrane is heated to react, and the color of the color changing agent changes in the reaction process, so that the progress of fire baking construction can be controlled according to the color change of the isolating membrane, and the fire baking temperature and the fire baking time can be grasped in time; and t
