Abstract:
1. A pavement slab, comprising: a top surface, a bottom surface opposite the top surface, first and second longitudinal side surfaces, each of which extends from the top surface to the bottom surface, and first and second transverse side surfaces, each of which extends from the top surface to the bottom surface; a first plurality of transverse holes formed within the first longitudinal side surface, each of which includes a first end and a second end opposite thereof, and a second plurality of transverse holes formed within the second longitudinal side surface, each of which includes a first end and a second end opposite thereof; a first plurality of pockets, each of which extends perpendicularly from the top surface to a corresponding one of the second plurality of transverse holes intermediate the first and second ends of the corresponding one of the second plurality of transverse holes; a first plurality of longitudinal holes formed within the first transverse side surface, and second plurality of longitudinal holes formed within the second transverse side surface; and a plurality of dowel bars, wherein each of the second plurality of transverse holes is sized and shaped to receive slidably a corresponding one of the plurality of dowel bars, and each of the second plurality of longitudinal holes is sized and shaped to receive slidably a corresponding one of the plurality of dowel bars, wherein each of the plurality of dowel bars positioned within its corresponding one of the second plurality of transverse holes is slidable between a retracted position, in which the dowel bar is positioned within its corresponding one of the second plurality of transverse holes, and an extracted position, in which one end of the dowel bar extends from its corresponding one of the second plurality of transverse holes and into a hole of a first external structure, and wherein each of the plurality of dowel bars positioned within its corresponding one of the second plurality of longitudinal holes is slidable between a retracted position, in which the dowel bar is positioned within its corresponding one of the second plurality of longitudinal holes, and an extracted position, in which one end of the dowel bar extends from its corresponding one of the second plurality of longitudinal holes and into a hole of a second external structure.
