PURPOSE: A boundary block for road is provided to reduce costs, enable firm connection to a neighboring boundary block and to maintain uniform height. CONSTITUTION: A boundary block for road comprises a body(10), and a connecting pin. Side grooves are formed on one or both sides of the lateral lower part of the body in longitudinal direction. The connecting pin is simultaneously inserted into the side groove of the body of a neighboring boundary block. The connecting pin make neighboring boundary blocks have the same height and applies coupling force to a space between the neighboring boundary blocks. |
