Abstract:
An apparatus for providing a roadway for the passage of vehicles there-over in a direction of travel, the apparatus comprising:a plurality of sections held together by a retainer, each section comprising: a top surface; a bottom surface; a front face extending between the top surface and the bottom surface from one end of the section to an opposite end thereof; a back face extending between the top surface and the bottom surface from one end of the section to an opposite end thereof; and a plurality of hollow tubes, each hollow tube extending from the top surface of the section to the bottom surface of the section and open at both surfaces of the section; wherein the front face of a first section and the back face of a second adjacent section substantially mate to form an interface; wherein the front face of the first section and the back face of the second adjacent section include a tongue and groove wherein a tongue is mounted on one of the faces and a mating groove is defined by the other face; and wherein the interface is oriented at a non-perpendicular angle to the direction of travel over substantially the length of the interface to reduce shock loading on the individual sections by allowing gradual weight transfer from the first section to the adjacent second section.
