1. A roadway section for enabling dynamic wireless power transfer to a vehicle, the roadway section comprising:
pavement material defining a pavement section volume having a top surface on which the vehicle traverses and side surfaces; and
a wireless power charger including a conductive element located at least partially within the pavement section volume and configured to emit a magnetic field toward the top surface of the pavement section volume to wirelessly transfer electric power to the vehicle,
wherein the conductive element defines a profile with an outer radius that is located at least two and a half centimeters (2.5 cm) away from the side surfaces of the pavement section volume, the pavement material comprises a precast slab, one of the side surfaces includes a cavity formed therein, the outer radius of the profile of the conductive element is located at a horizontal distance of at least two and a half centimeters (2.5 cm) from the cavity, and the pavement section volume includes a portion outside the outer radius of the profile of the conductive element, further comprising a sensor loop located above the portion outside the outer radius of the profile.
