Existing pavement evaluation methods are performed at a section level that yield estimated quantities of work at approximate locations. However, this is not sufficient to generate design plans and calculate the true repair costs. Using advanced global positioning system (GPS) and geographic information system (GIS) techniques, this asset management solution solves these challenges by allowing inspectors to capture the precise location of defects which are then immediately and spatially associated to the assets based on geo-fenced pavement inventory. Repair crews are able to navigate directly back to the reported defect with accuracy (up to 2 cm horizontal and vertical positioning) to eliminate any potential superfluous repairs. The data captured in the end-to-end process allows the back-office to perform quality control and analyze and monitor asset lifecycle developments in real time to enable proactive and predictive airfield repair decision making. A pilot airport project focused on pavement inspection, design, and construction process. During the inspection phase, the data captured included everything contractors needed for bids and was available immediately when the inspections were completed which greatly reduced the time to create work estimates. The defect dimension data, along with the defect images captured during the inspection, helped make the re-inspection process more efficient by providin g a “before and after” view of the repair site. Improvements in each step in the design and construction process led to an overall reduction in closure time and an efficient and cost-effective process. INTRODUCTION The objective of an effective pavement management system is reliable, accurate, and detailed pavement condition data. Pavement condition data are used to model pavement performance, develop maintenance and rehabilitation schedules, and evaluate program effectiveness. Having quality pavement condition data is directly linked to the ability of an agency to extend the life of pavements by developing reasonable and reliable maintenance program and recommendations. Pavement management is a systematic approach to forecasting pavement Maintenance and Repair (M&R) requirements in a cost-effective manner. The primary objective of pavement management is to preserve pavements in good condition rather than wait for them to fail and then reconstruct them. When the appropriate preventive M&R treatments (e.g., crack sealing, patching, joint seal, etc.) are applied at the correct times during a pavement’s service life, these
