Claim:
A system for forming a pre-fabricated warped pavement slab comprising: a plurality of individual form sections for forming a pre-fabricated pavement slab, said plurality of individual form sections including a plurality of spaced stiffeners that are flexibly affixed to each other, wherein said plurality of spaced stiffeners are moveable by raising or lowering to create a warp; a device for adjusting the slopes of the plurality of the spaced stiffeners, wherein said device for adjusting the slopes is configured to be positionable and alignable at an angle across said spaced stiffeners such that when said device for adjusting the slopes is moved either by raising or lowering said plurality of spaced stiffeners from a set of the first set of slopes to a second set of slopes, the slope of each of the moved spaced stiffeners will each be at a different slope with respect to each of the other moved spaced stiffeners; and a plurality of side rails positioned on said individual form sections for receiving hardenable, flowable material.
