Abstract
A pavement system includes a slab having a body comprising pavement materials presenting a top surface. The system includes a reinforcement layer comprising geogrid materials embedded in the body, strain sensors fixed to the reinforcement layer, and a processor configured to collect multiple electrical signals across time from each of the strain sensors and to analyze the electrical signals to determine one or more of: (A) risk of a structural defect in the slab, (B) risk of a problem with underlying sub-grade beneath the slab, and (C) movement of passing objects across the top surface.
