ABSTRACT:
A roadway for bicycle and other tired wheel vehicles formed of a plurality of end-to-end abutting tiles, preferably of a structural foam plastic such as polyethylene includes a generally rigid base having opposed top and bottom surfaces, with the top surface being flat and carrying integrally longitudinally and laterally spaced arcuate ridges. The arcuate ridges form alternating, laterally aligned rows of longitudinally spaced, oppositely facing arcuate ridges, with the arcuate ridges of a given row being offset laterally from corresponding arcuate ridges of adjacent longitudinally spaced rows by one half the length of an arcuate ridge. Further, the arcuate ridges of each lateral row are spaced from each other a distance such that the ends of the arcuate ridges of a given row lie within the concave curve of arcuate ridges of the adjacent, oppositely facing lateral row. As such, a bidirectional roadway is created, minimizing vehicle wheel vibration, permitting easy rolling of the vehicle wheels, while providing slip resistance to the vehicle wheels in all directions. Preferably, a narrow rib extends longitudinally of each arcuate ridge along the center thereof and drainage holes are preferably provided between the ends of the arcuate ridges of each row centered within the concave curve of the arcuate ridges of an adjacent facing row.
