istorical records of construction and repair may not exist or be hard to locate. Noggin® GPR systems enable highway engineers to easily assess subsurface conditions over vast lengths of road.
EKKO_Project Interpretation module enables zoning and layer thickness determination. The database can be used to create summary reports such as statistical tables or electronic files for export into Pavement Management Systems (PMS) and GIS systems.
Data in the figure 2 to the right identifies zones, from the road section shown in the above Google Earth™ map, that may need further study. The figure also illustrates a zoomin on a critical area.
The zoning display at top shows where unusual features have occurred. Interactive software enables viewing at a variety of scales. A zoom in on the feature at 11750 m shows a former repair zone that has been overlain by newer asphalt.
When learning about GPR, the best practice is to review several similar case studies to develop an understanding of variability. Check for other insightful information on the resources tab to learn more.
