A kerb block length is greatly reduced as compared with the length of a conventional kerb stone. The greatly reduced length allows the kerb block to be handled easily by a single operative and eliminates the need for curved kerb stones. The block is of generally cuboidal shape with edge cut away as shown to provide a step and an inclined surface 5. It can be positioned with the side AB horizontal to provide a driveway-access ramp, or with the side BC horizontal. Pairs of opposed blocks may be used to form (a) a drainage channel or (b) a "sleeping policeman" speed restriction hump. <IMAGE> |
