This project aims to develop a predictive framework for joint activation timing in jointed plain concrete pavements (JPCPs) and overlays to reduce the risk of random cracking and premature pavement distress. The research will combine an extensive literature review with the development of a fracture mechanics–based finite element model capable of simulating concrete strength and stiffness development, saw-cut timing, and interaction between adjacent joints. Field and/or laboratory testing using ultrasound tomography will be conducted on newly constructed pavements to monitor joint behavior from saw cutting through activation, providing data to validate the model. The project will culminate in a predictive tool and sensitivity analysis to inform construction practices—particularly saw-cut timing and related variables—to improve short- and long-term pavement performance.
