Dealing over the years its own unique simultaneous engineering, SINECO has designed and offered various software applications for computer aided management of airport and road networks.

The Company mission is to provide customized application to management companies in terms of tools easy to be dealt: intuitive but at the same time provided with effective graphic interface,

or such one as to allow immediate access to all relevant information.

In particular, the Arc Utilities Airport® software has been implemented and conceived as an ESRI basic software application. Thematic mapping, geocoding and consultation functions are

guaranteed by ArcView directly and this allows the publication of a georeferred mapping of fl ight infrastructures and relating, associated data, such as anagraphic, structural (PCN, Modules,

etc.), functional (PCI, IRI, ruts, etc.) data, periodical inspections, data on maintenance works and so forth.

The company has 2 dynamic heavy weight defl ectometers, specifi c for airport pavement studies.

These tools make possible a fast and accurate identifi cation of mechanical properties (Elastic

Modulus) of pavement layers and the subgrade, identifi cation of structurally poor sections and any

consequent reenforcement works.

This equipment applies an impulsive load to the pavement, which reproduces the load generated

by the aircraft taken as a reference and automatically measures defl ection basin produced. Load

is given by a heavy weight falling on a plate positioned on the pavement, from a pre-determined

height, whereas a series of sensors (up to 9) are positioned along a bar and automatically detect the

defl ecting basin generated by the load.

The impact generates a peak force which can reach up to 240 kN, thus also reproducing heavy loads

induced by aircrafts such as Boeing 747.

This equipment is normally used to test the structural properties of “airside” infrastructures

(aprons, runways, taxyway, etc.) and for the classifi cation thereof according to Annex 14 of ICAO’s

ACN/PCN procedure. With regard to rigid pavements, this can also be used to test the degree of

joints performance by calculating the LTE (Load Transfer Effi ciency) index.

This can obviously also be used while works are being carried out, in order to check whether

new pavements com-

ply with contractual

technical specifi ca-

tions and, in the fi nal

stage, to test their

suitability for airline

traffi c in accordance

with ENAC Rules.

ARAN is a sophisticated mobile laboratory which, thanks to the various equipment installed onboard, allows an au-tomatic, constant speed and complete analysis of the geometric and functional condition of airport pavements, both rigid and fl exible.In particular, ARAN allows to measure surface geometric features of each fl ight infrastructure, detecting transver-sal/longitudinal crossfall, transversal/longitudinal profi le and curve radiuses as well as to compare the values measured within the limitations set forth by ENAC/ICAO Rules. In addition to geometry, all parameters can be acquired with regard to the functional condition of a pavement, namely:• Longitudinal roughness expressed in terms of the IRI index (ASTM AND 1926-08), BBI index, “Boeing Bump Index”

(FAA - AC 150/5380-9) as well as other indexes, such as the CP “Planar Coeffi cient” index, RCI (Riding Comfort Index), etc.;

• Transversal roughness, measured through rut depth calculation;• Longitudinal eveness, measured on different “straightedge” bases, having a wavelength equal to 3.0 - 45,0 metres;• Surface macrotexture expressed in terms of MPD ”Mean Profi le Depth” (UNI EN ISO 13473-1) and ETD “Estimated

Texture Depth”;• Surface “distress” conditions, measured by type, size and severity, through the collection of pavement high-resolu-

tion images, thanks to the LRIS system (pls. see description below) and the subsequent calculation of PCI “Pavement Condition Index” (ASTM D5340-09) index.

For the purposes of acquiring longitudinal roughness data, two Class 1 laser profi lometers are installed, in compliance with ASTM E950-98 rules, whereas with regard to transversal roughness data, the vehicle is endowed with a max 3.80 metres-long front bar, with a series of ultrasonic transducers, mounted in a row, at a 10 cm distance from one another.All data collected by ARAN are integrated and geore-ferred in space, thanks the POS Applanix LV-420/200 localisation system, which combines a satellite naviga-tor (GPS), an inertial platform (IMU) having a frequency equal to 200 Hz and a high-precision odometer (DMI).

Lynx Mobile Mapper performes a georeferred scan of airside&landside infrastructures and territory in dynamic mode, also during night time, reaching a speed of up to 100 Km/h.In short, its functioning consists of: 2 last generation Lidar sensors, positioned on top of the vehicle, emitting laser beams with a frequency of up to 400,000 impulses per second, rotating at a maximum speed of 12000 rotations per minute. Laser beams are refl ected by the objects present in a strip of over 200 metres and thus read by a receiver which measures their distance. The totality of points reproduce the airport infrastructure and the territory as a high den-sity “Point Clouds” (1,000 – 4,500 points per square metre) each of whom, thanks to the presence of an Applanix-POS LV 420 locali-sation module, is georeferred in space with a high precision, according to the WGS84 coordination system.Fields of usage are very varied, from fl ight infra-structure 3D Modelling to transversal/longitu-dinal section/profi le extraction, contour lines, geometric dimensional tests, tests on potential water puddle areas, tests on the correct positioning of horizontal signals with respect to plans, etc.

This is an application running on the ArcGis (Esri) platform, built in collaboration with One Team Srl (Milan), specifi cally designed for the management of airport networks, both for the “airside” and for the “landside” infrastructures.The software allows the automatic insertion, viewing, constant update and ex-traction of the structural and functional information of each single entity forming part of the airport network. It is thus possible to manage different types of information, such as indexes typically characteri-sing pavements maintenance (PCN, PCI, IRI, FOD, etc.), geometric/topographic infrastructure data (sections, crossfalls, contour lines, etc.), inspection data (alphanumeric and photographic) acquired on-site through GPS/hand-held device, data on maintenance works, photographic images of pavements acquired by the LRIS system described above and so forth.This application allows to obtain detailed alphanumeric and graphic reports, with prin-touts, including printouts on a scale, to directly intervene on a geodatabase, through fun-ctions allowing a “real time” data updates and data pro-cessing.Lastly, through the PMDS® (Pavement Maintenance Decision System) module addition, a simple and effective planning of pavement maintenance is possible. In particular, thanks to the implementation of specifi c algorithms and starting from typical state indexes, the module prioritises airport sections which require assistance in the short and medium term, identifying the best recovery type for each of them, the relating expense budgets and the consequential analy-sis of alternatives. The modu-les follows the instructions set forth in the Federal Aviation Administration AC-150/5380-7 and AC-150/5380-6b rules.

• Number of lines per second: 28,000 lines• Number of pixels per line: 4096 pixels• Visual fi eld: 4.00 m (3950 mm nominal)

• Transversal resolution: 1.00 mm• Longitudinal resolution: 1.00 mm (a 100 km/h)

Thanks to the Applanix-POS LV 420 localisation system, all the

images collected are codifi ed and georeferred in space, so as to be

subsequently placed on an airport reference cartographic map and

managed by way of GIS.

Sineco’s specifi c software make possible the automatic proces-

sing of pavement images, quantifi cation of severity of each type of

deterioration detected and, lastly, to obtain indexes for common use.

With regard to indexes, the PCI “Pavement Condition Index” (ASTM D5340-09), PCR “Pavement Condition Rating” and the potential FOD “Foreign Object Damage” index are particularly important.

The “Laser Road Imaging System’” (LRIS) equipment is installed at the back of the ARAN vehicle and is specifi cally aimed at detecting pavement distress. The equipment consists of 2 linear scanning digital cameras, capable of acquisition at a maximum frequency of 28 kHz (28,000 lines per second, that is 1 line per mm at a speed of 100 km/h).The lighting system consists of 2 infrared laser sensors (one for each camera) having a 250 W power ( 808 nm), with fi ngerprint area of (190*0.1) cm2. Thanks to specifi c software, the two systems (camera and laser) are perfectly synchronised so that the scanning performed by each camera is illuminated by the corresponding laser.The system is confi gured so that the right laser serves the left camera and vice versa and illumination is achieved with an incident angle which improves contrast and thus the visibility of cracks in pavement.The high-defi nition of images allows to detect fi ne cracks up to a width of 1 mm and, thanks to laser lighting, detection reaches an optimum level at any time of the day, and also at night time. The two cameras (right and left) are synchronised and sensitive software allows to “stick” left and right photograms together so as to have a single view of the whole detected breadth (4.00 metres).

The images collected are saved in “jpg” format onto an appropriate 300 Gb removable hard disk. The system specifi cations are as follows:

Database building up and PMSSineco avails itself of GSSI’s GPR Mod. Sir 10H georadar equipment, with antennas having different acquisition frequencies, which allows to determine and calculate stratigraphy in airport super-

structures, identify any faults and, if necessary, map subservices.

A 2500 MHz bistatic antenna, kept 45 cm above pavement level, because of reduced wavelength allows better resolutions (approximately 2-3 cm) in the most superfi cial layers (asphalt concrete

-or slab- and foundation layer), with a penetration capacity of approximately 50-60 cm. A 400 MHz monostatic antenna allows to survey up to a depth of 3.0-3.5 m, with a resolution slightly above

10 cm. After partial refl ections in discontinuous surfaces, refl ected signals are detected by a receiving antenna and sent to the central unit, where they can be amplifi ed and/or subjected to fi ltering.

Detection is continuously carried out at a maximum speed of approximately 80 Km/h, with a spatial

resolution of 50 cm and, if acquisition speed is reduced, at centimetric resolutions as well.

While acquisition is in progress, a radargram can be viewed on a special display, representing the

received signals according to the arrival time and the relative distance travelled by the antenna,

measured through a specifi c precision odometer.

Equipment is employed both while tests are performed on the thickness of materials used compared to the values contained in the technical specifi cations and for the purposes of structural characterisation of pavements in use, where strata composition and nature is unknown.
