ABSTRACT:
A rigid concrete slab for conveying vehicular or railroad traffic which is provided with functional longitudinal beams that extend or protrude downward from the underside of the slab and are fully and continuously supported by the underlying material. The attached beams enhance, strengthen and stabilize both longitudinally and transversely. Friction and suction, or interface adhesion, between the beams and the underlying material in which it rests causes the beams to act as anchors thereby further resisting displacement or distortion of the slab.
