Bidirectional roadway for wheeled vehicles
First Claim
1. In a roadway for bicycle and other tired wheel vehicles comprising a molded modular, self-supporting track extending longitudinally in the direction of vehicle travel and including a generally rigid roadway base having opposed top and bottom surfaces, a plurality of transversely arranged, arcuate ridges carried by said base and projecting upwardly therefrom above said top surface for engagement with a tire tread, individual arcuate ridges being spaced from each other longitudinally and laterally, the improvement wherein;
- said arcuate ridges form alternating lateral rows of longitudinally spaced, oppositely facing arcuate ridges,said 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, andsaid arcuate ridges of each lateral row being spaced from each other a distance such that the ends of the arcuate ridges of a given row lie within the concave curve of the arcuate ridges of an adjacent, oppositely facing lateral row, whereby;
a pattern of interlocking traction arcuate ridges minimize vehicle wheel vibration, allow easy rolling of the vehicle and provide slip resistance to the vehicle wheels in all directions, while facilitating bidirectional travel of the vehicles longitudinally over the roadway.

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.
