Abstract

The present invention provides a precast panel for road paving that includes a main body formed with a set thickness having an upper surface, a lower surface, and a side between the upper and lower surfaces, and a joint provided on the side of the front end of the main body to connect adjacent main bodies, so as to improve the joint structure between precast panels to strengthen shear force and secure rigidity while maintaining simplicity; wherein the joint includes a ledge formed continuously along the side and protruding outwardly by being stepped in the vertical direction on both opposing sides, and a recess formed inwardly to engage with the ledge of an adjacent main body.
