Digital twin technology for road pavement

In recent years, the concept of Digital Twins (DT) has emerged as a promising solution for real-time monitoring and proactive maintenance of complex engineering systems. This systematic review paper provides a comprehensive overview of the current state-of-the-art in DT technology for road pavement. The paper aims to bridge the gap between the theoretical physic-based model and DT and its practical implementation in road pavement. Through a rigorous review of the literature, this study identifies the key components, challenges, and opportunities associated with the utilization of DT for road pavement. The results show that road pavement DT research is still scarce and that only a few use cases in pavement reactive maintenance have attracted the attention of the scientific community. By synthesizing the findings of this study, the paper offers insights into the prospects of DT in revolutionizing pavement proactive maintenance practices and enabling more efficient and sustainable road infrastructure.
