| Summary: | Pavement roughness evaluation of airport runways/taxiways and scheduling of maintenance operations should be done according to
well-defined procedures. Survey of geometric features of airport pavements is performed to verify the flow of water from the surface
and to assure a level of roughness that allows the airplane to maneuver in the safest and most comfortable conditions.

In particular the evaluation of longitudinal and transversal evenness of the runway and taxiway is carried out through topographic
survey. The tachymetric survey has been carried out according to traditional topographic technique, which allows the evaluation of
geometric position of isolated points with very high accuracy, but it is not very productive. Moreover it returns the pavement surface
model through only few measured points. An alternative survey method, characterized by a good accuracy, high speed of acquisition
and very high surveyed point density, is Terrestrial Laser Scanning (TLS), in static mode. In this paper we describe our experience
aimed to validate the use of time-of-flight (TOF) TLS, based on a survey on a 200 m length segment of an international airport
taxiway. From the acquired data we extracted the parameters of interest, especially the slope, and compared them with the values
obtained from the traditional topographic survey. We also developed a proprietary software package to evaluate the slope and to
analyze the statistical data. The software allows users to manage the flow of a semi-automatic calculation. |
