Durable and Constructible Materials in Glass Reinforced Concrete to Efficiently Accommodate Magnetic Fields

Inductive power transfer systems (IPTS) embedded in concrete pavement panels allow electric vehicles (EVs) to charge their batteries while in motion. Four prototype concrete slabs were constructed and monitored during high-cycle fatigue loading. After the fatigue tests, each slab was subjected to a static load until failure. Traditional metallic reinforcement was not an option due to the adverse effects of the magnetic field produced by the IPTS. During the fatigue testing, all alternative slabs experienced differing degrees of cracking. The data from strain gauges were used to compare the deformation due to fatigue damage that occurred in each slab. In addition to the physical testing of the concrete slabs, each alternative slab was modeled in a 3D finite element analysis (FEA) program. The results of the FEA models provided the theoretical ultimate strength of each test slab before they were subjected to fatigue damage; these results were compared with the ultimate residual strengths of the test slabs obtained during physical testing. The data obtained during this research suggest there are several viable top mat reinforcement alternatives, and the fiberglass reinforced plastic (FRP) grid used as top mat reinforcement provided the greatest durability for the concrete slabs.
