1. A computer-implemented method for pavement slab analysis based on data regarding transfer of force through a sensing volume responsive to exertion of weight on the sensing volume by passing objects, the method comprising:
receiving, at a processing element, electrical signals from a plurality of strain gauges embedded in a precast pavement slab defining the sensing volume, the plurality of strain gauges being distributed across an XY coordinate plane, the XY plane being parallel to a top surface of the pavement slab; and
analyzing, at the processing element, the electrical signals to determine one or more of the following: (A) risk of a structural defect in the pavement slab, (B) risk of a problem with underlying sub-grade beneath the pavement slab, and (C) movement of the passing objects across the top surface;
the pavement slab being attached to an adjacent slab with one or more load-transferring connectors.
