A paving stone is provided to prevent a gap from being generated by increasing the unity force of paving stones with the rubble press-inserted in a groove. A paving stone(100) has grooves(110) which are consecutively formed along the exterior circumference of the paving stone to be inserted to the inside of the hardened rubble(200). The paving stone is made in the regular hexahedron or rectangular hexahedron. The groove is formed in the exterior of the paving stone to consecutively pass four sides. A pair of grooves are side by side arranged. |
