Abstract

In recent years, the growing need for intelligent infrastructure has drawn attention to multifunctional asphalt concrete technologies, particularly those capable of self-sensing, self-heating, and self-healing. Among these, conductive asphalt concrete, created by incorporating conductive fillers such as graphite, carbon fibers (CF), or carbon nanotubes (CNT), has emerged as a promising solution to improve road maintenance, especially under extreme weather conditions. This study reviews the current research trends and experimental findings in Korea concerning the electrical resistance characteristics of conductive asphalt mixtures. Emphasis is placed on material types, mixing ratios, experimental setups, and performance evaluation methods. Key findings from domestic studies indicate that the addition of conductive materials significantly reduces electrical resistance, and the sensitivity of resistance change to mechanical stress can enable real-time structural monitoring. For instance, CNT-CF hybrid composites have demonstrated superior conductivity and network stability compared to single-material systems. Graphite-enhanced asphalt has shown effective self-heating performance for snow melting applications, while the integration of CF into cementitious matrices has offered insights into the percolation threshold and conductive behavior under varying loading conditions. This review not only summarizes the results of electrical resistance measurement tests in Korean research but also highlights the practical limitations and future research needs. The analysis aims to provide a foundation for scaling up these technologies for field application and supports the development of smart pavement systems that align with the evolving demands of infrastructure management.
