Using 3D Pavement Surveys to Create a Digital Twin of Your Runway or Highway
Highway departments and airports perform regular pavement condition inspections in order to record pavement distress data, which are important inputs into pavement management systems (PMS). Increasingly pavement condition data are captured using high-speed 3D lasers and high-accuracy blended inertial positioning systems. This enables fast, accurate, and objective pavement assessment. Recent advances in 3D scanning and GNSS positioning data integration now permit these routine pavement inspections to deliver much more value; effectively creating a “3D Digital Twin” of roads and runway surfaces. These 3D Digital Twins can provide a much richer data set to the asset manager while reducing closure time, data collection costs, and staff exposure. 3D Digital Twins can be directly imported into road design software applications and used to generate volumetric estimates, preliminary, and final designs. Outputs of 3D design software can then be sent to laser tracking total stations in order to control 3D pavers and milling machines such that better-designed surfaces are now possible. This paper and presentation present details of the capture technology, key workflow steps, and finally point density and accuracy compared to traditional.
