SPR-4521: Comprehensive Pavement Patching Tools and Web-based Software for Pavement Condition Assessment and Visualization

The project will develop guidelines for concrete patching slab removal and creation of patching interface in full depth hot mix asphalt (HMA) patching. In addition, the project will implement in MATLAB and Python an algorithm that incorporates data from falling weight deflectometers (FWD), ground penetrating radar (GPR), and 3D to produce patching tables with the required patching depth as an output. Finally, the project will deliver web server software needed for visualization of the patching table including the data sources (FWD, 3D image, and GPR) used in its creation.
