After the concrete pouring is completed, it is necessary to timely maintain the road surface to improve the performance of the road surface and extend the service safety and service life of the road.

[0003] The prior art discloses an asphalt pavement cooling device for road engineering, which includes a first water tank. A hook is arranged on the left side of the outer wall of the first water tank. Wheels are arranged at the four corners of the bottom of the outer wall of the first water tank. A cooling mechanism is arranged on the first water tank. The cooling mechanism includes: a semiconductor refrigeration sheet fixedly installed on the left side of the inner wall of the first water tank; a sealing plate fixedly installed on the inner wall of the first water tank and attached to the right side of the semiconductor refrigeration sheet; a water inlet hole opened on the right side of the top of the first water tank; a water inlet fixedly installed on the top of the outer wall of the first water tank and communicated with the water inlet hole; a pipeline fixedly connected to the right side of the outer wall of the first water tank and communicated; a valve fixedly installed on the pipeline.
