Induced heating-healing of conductive asphalt concrete

Oct 01, 2021  The observations showed that the induced heating-healing rate of asphalt concrete made of siliceous aggregate was more than that of limestone aggregate (Jahanbakhsh et al., 2018). This observation attributes to higher electrical conductivity and sensitivity of siliceous aggregate to electromagnetic radiation compared to limestone aggregate.
