Development of a Finite Element Model for Electrically Conductive Concrete Heated Pavements

An electrically conductive concrete (ECON) heated pavement system (HPS) is a promising snow and ice removal technology for airports presenting advantages of enhanced safety for ground crew servicing the aircraft, reduced dependency on deicing salts, and minimal use of snow removal equipment. ECON works by applying an electrical current through electrodes embedded into the ECON layer to generate heat generated by resistive losses to melt ice/snow on paved surfaces. A 3-D FE model of the ECON slab (122 cm long x 86 cm wide x 10 cm thick) built at Iowa State University (ISU) was developed and validated through comparison with experimental test results produced by using decoupling thermal-electrical analysis of a phenomenon described as joule heating. The results demonstrate that the developed 3-D FE modeling approach can be utilized as a cost-effective evaluation tool for examining effects of various design parameters on the time-dependent ECON heating performance for ECON HPS design optimization.
