1. A modular pavement slab comprising:

  • a body including a top surface, a bottom surface, and four side surfaces, the modular pavement slab configured to be coupled to at least one other modular pavement slab via connectors along at least one of the side surfaces;

    a strain sensor array retained within the body, the strain sensor array configured to detect a plurality of strains on the body resulting from vehicular traffic across the top surface of the body;

    a sensor processor in communication with the strain sensor array and configured to—

    communicate input signals to the strain sensor array,receive output signals from the strain sensor array,determine a plurality of time-varying strain values, each strain value indicating a strain experienced over time by a successive one of a plurality of regions of the body; and

    a plurality of dowel cavities defined by the body;

    said connectors comprising a plurality of dowel rods extending from a first side surface of the four side surfaces,said plurality of dowel cavities extending into the body from a second side surface of the four side surfaces, the second side surface being substantially opposite from the first side surface.
