Abstract
A system 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 including a precast pavement slab defining the sensing volume and having a top surface, a plurality of strain gauges embedded in the pavement slab within the sensing volume, and load-transferring connector(s) attaching the pavement slab to an adjacent slab. The strain gauges are distributed across an XY coordinate plane parallel to the top surface. The system also includes a processing element and computer-readable instructions for receipt of electrical signals from the strain gauges and to analysis of 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.
