Abstract
A segment of roadway includes a body having a top surface and a strain sensor array comprising one or more optical fiber cables embedded in the body. The strain sensor array includes an integrity sensor and vehicle-strain sensors. The vehicle-strain sensors are configured to detect strain on the body resulting from vehicles traveling across the top surface. Each of the vehicle-strain sensors has at least one of a spatial resolution and a length extending substantially parallel to a direction of travel of equal to or less than fifty centimeters (50 cm), and the integrity sensor has at least one of a spatial resolution and a length of greater than fifty centimeters (50 cm).
