A module for use in constructing a pathway for traffic comprises a base member that defines a lateral groove disposed at its perimeter edge and extending along a first end, and a tongue structure disposed at its perimeter edge and extending along a second end. The tongue structure is received in the lateral groove and comprises a plurality of tongue portions that includes a first type of tongue portion and a second type of tongue portion disposed in alternating relation along the length of the tongue structure, to thereby define a throughpassage for receiving a securing rod. The first and second tongue portions have no vertical overlap one with the other. To form a pathway for traffic, the modules are placed in perimeter-edge to perimeter-edge relation, with the tongue structure of the modules inserted into the lateral groove of an adjacent module, and are secured together by the securing rod. |
