UAV Pavement Inspection

Paul Fassam Geomatics Ltd has been pioneering drone technology around airfields for some time now. UAV pavement inspections are our latest offering which promise to revolutionize this historically slow practice.

Using either a multi-rotor or fixed wing aircraft, a low-level grid is flown over the hardened areas. High-resolution photography captures the surface to a resolution in excess of 3mm. These photos are then rectified to produce a flat 1:1 image of the entire survey area. The image allows pavement inspectors to safely measure and mark features in the safety of their office.

Overal this method greatly improves the deliverable whilst also saving time on site. The UAV can operate safely between flights under the control of ATC.

Interpretation of historical data

PAS 128 provides a robust methodology for delivering utility surveys in the UK. It focuses on levels of accuracy – referred to as Survey Category Types – that you can specify when requiring a PAS 128 compliant underground utility survey.

There are four Survey Category Types ranging from D - A:

PAS 128 Survey Category Type D

Underground utility plotted from utility record data only (not detected by geophysical methods).

PAS 128 Survey Category Type C

Underground utility plotted from utility record data only, but with site reconnaissance to match utility record with physical utility street furniture as a best fit.

PAS 128 Survey Category Type B

Utility detected by geophysical methods (single or multiple) to obtain a horizontal position and/or vertical position. (Depth) For the positional accuracy of each QL-B sub category please refer to the Accuracy Diagram.

PAS 128 Survey Category Type A

Utility verified and positioned by physical identification. This may be by strategically positioned vacuum excavation, hand dug trail pitting or by visual inspection within a utility chamber.
