In this paper, a new self-sensing pavement for vehicle detection is designed. Smart nickel particle filled cement-based sensors with high sensitivity are used as vehicle detector. The sensor array is embedded into a concrete pavement to form the self-sensing pavement. The vehicle detection capability of this pavement is investigated in outdoor road tests. Experimental results show that the proposed self-sensing pavement can accurately detect the passing vehicles. This finding indicates that the self-sensing pavement embedded with smart cement-based sensors has a great potential for traffic detection and monitoring.
