Patent ID: 7004674

Claim:
A method for installing a pre-fabricated warped pavement slab, comprising: placing a pre-fabricated warped pavement slab on a graded subbase; and placing a binder material between a bottom surface of the warped slab and the graded subbase wherein a slab is defined as a body of uniform thickness having top and bottom surfaces and sides connecting the top and bottom surfaces, and having edges such that all edges are straight, wherein a slab edge is the intersection formed between any side and either the top or bottom surface of the slab, and warped requires a top surface of the pavement slab to have all its points not in a single plane, such that both resultant edges of a cross section cut taken perpendicular to a longitudinal side are straight, further wherein if any non-perpendicular to the longitudinal side cross section is taken of the warped slab, the resultant edges will be non-linear.
