Development of Self-Sensing Asphalt Pavements: Review and Perspectives

Abstract

The digitalization of the road transport sector necessitates the exploration of new sensing technologies that are cost-effective, high-performing, and durable. Traditional sensing systems suffer from limitations, including incompatibility with asphalt mixtures and low durability. To address these challenges, the development of self-sensing asphalt pavements has emerged as a promising solution. These pavements are composed of stimuli-responsive materials capable of exhibiting changes in their electrical properties in response to external stimuli such as strain, damage, temperature, and humidity. Self-sensing asphalt pavements have numerous applications, including in relation to structural health monitoring (SHM), traffic monitoring, Digital Twins (DT), and Vehicle-to-Infrastructure Communication (V2I) tools. This paper serves as a foundation for the advancement of self-sensing asphalt pavements by providing a comprehensive review of the underlying principles, the composition of asphalt-based self-sensing materials, laboratory assessment techniques, and the full-scale implementation of this innovative technology.

Evaluation of Skid Resistance and Comfort of Pedestrian Pavement with Asphalt-Based Wood Chip

“…Good comfort on the road surface is a prerequisite for healthy pedestrian walking [18]. Walking or running on the road can cause some damage to the knees, and comfortable shock-absorbing shoes can reduce knee joint damage [19]. A highly comfortable road surface can further minimize joint wear and tear, achieving healthy walking.…”
