Modeling the use of an electrical heating system to actively protect asphalt pavements against low-temperature cracking

This paper addressed the case of an electrically heated asphalt pavement; it explored unconventional application such a system – not for combating snow and ice but mitigating low-temperature cracking. The investigation was done in silico, considering stratified medium to represent pavement system, thin heat-generating layer heating measured weather conditions from Greenland emulate cold region that can potentially produce thermal A thermomechanical model outlined, consisting one-dimensional formulation accounts (also) latent heat effects, three-dimensional mechanical based on linear viscoelasticity assumes thermo-rheological simplicity. cold-weather event, leading crack, identified by model. Additionally, parametric carried out quantify effects system’s embedment depth production activation timing needed prevent It is found cracking with embedded electric attainable workable. Doing so most effective when resides close ride surface. procedure automatic operation proposed practical implementation.
