Abstract

It is a common practice among state agencies to manually inspect road segments and decide maintenance requirements based on the pavement condition index (PCI). However, standalone PCI only evaluates the pavement surface condition. When coupled with the variability in human perception of pavement distress, this limits the accuracy of current pavement maintenance practices and undermines the automated pavement maintenance suggestions systems, especially for actionable recommendations related to accurate patching location, depth, and priority. This project explores integrating pavement structural and surface condition assessment with pavement ratings of distress to estimate the appropriate pavement patching strategy for accurate location, depth, and quantity. The developed patching management tool will provide an automated pavement management option with high resolution patching location and improved patching depth and priority suggestions.
