The invention discloses rapid repair glue for roads and bridges. The rapid repair glue comprises a machine body, a first cavity, a first sliding cavity and a first transmission cavity, wherein the first cavity with an opening facing upwards is formed in the machine body, the first sliding cavity is formed in the machine body, and the first transmission cavity is formed in the machine body. A second cavity communicating with the outside is formed in the bottom wall of the first sliding cavity, a rack extending front and back is fixedly installed in the top wall of the first sliding cavity, a first sliding block is arranged in the first sliding cavity in a front-back sliding mode, the bottom of the first sliding block extends into the second cavity, and a third cavity with an opening facingupwards is formed in the top wall of the first sliding block. The rapid repair glue is simple in structure and convenient to operate, crushing is carried out on road surfaces by using a reasonable mechanical structure, mixing of the repair glue and leveling of the road surfaces are carried out step-by-step by utilizing the same power source, an automatic feed mechanism is arranged in the using process, processes cooperate with one another without affecting each other, maintenance efficiency of the road surfaces is improved, and practical performance of the rapid repair glue is improved.
