Abstract
En 中文
• Concrete pavement prestressed with smart steel strands can self-sense vehicle load. • The smart cross-tensioned concrete pavement shows a 100% sensor survival rate and engineering feasibility. • A novel method for identifying dynamic vehicle weight, trajectory, and speed is proposed. • The full-scale field experiment proves the sensing accuracy for vehicle weight and speed can reach 85% and 95%, respectively. • A self-sensing strategy is developed to real-timely detect vehicle parameters based on the time domain moving window.
