EVALUATION OF EXISTING PAVEMENTS (AIRFIELD)

YZTECHNOLOGY pavement evaluation and analysis of collected data are effective in rapidly identifying pavement properties and in determining the remaining structural life capacity of a pavement.

FUNCTIONAL EVALUATION :

Performs visual condition surveys, which entirely inspecting the pavement surface for both structural and functional distresses and deterioration. Visual condition surveys provide data for both network-level pavement management systems and project-level rehabilitation studies. YZTECHNOLOGY performs both manual and automated pavement condition surveys, using Pavement Condition Index ( PCI ) and MicroPAVER nomenclature will be utilized for all data input and output.

STRUCTURAL EVALUATION:

The HWD is the preferred device for conducting non-destructive deflection since it has an expanded loading range, simulating up to a heavy aircraft such as the Boeing 747 ( one wheel ). Further, the HWD can properly introduce anticipated load/deflection measurements on even heavy pavements such as thick airfield pavements.
These equipments provide data for:
• Project-level rehabilitation studies
• Network-level structural characterization
• Overlay and reconstruction design
• Load transfer and loss support studies for concrete pavements
• Assessment of structural support of sub-grade and pavement layers during construction

The ACN/PCN system of rating airport pavements is designated by the International Civil Aviation Organization (ICAO) as the only approved method for reporting strength. For analysis of airfield pavements, ( WinPCN ), which calculates PCN-values in accordance with the ACN/PCN method, as described in the ICAO design manuals. files from Dynatest FWD/HWD equipment to calculate A CN/PCN values based on the methods used by ICAO. Additionally the ACN/PCN program can calculate a PCN value based on aircraft A CN values and sub-grade CBR values as described in FAA Circular 150/5335 -5. The program supports both ICAO and FAA standards.

SAFETY EVALUATION

• Friction Testing
• Roughness Testing

Safety Evaluation survey, which requires pavement friction testing, pavement roughness profile testing.  Douglas equipment Mu-Meter runway friction measuring and reporting system. The Mu-Meter is a continuous friction measuring and reporting system designed for maintenance testing to evaluate surface friction changes due to weathering, high usage, aging, and contaminants such as rubber build-up in the touchdown zones in airfield. Douglas Mu-meter as runway measurement system, it meets all the FAA and ICAO specifications for friction measuring devices.

PAVEMENT MANAGEMENT FOR AIRPORTS

Pavement Management is a systematic method for tracking and addressing pavement condition at the network level. Airports and aviation authorities are becoming busier by the day, and this trend is going to increase significantly in the near future. Heavy airport traffic makes it difficult to plan and carry out pavement preservation and repair projects. Runway closures must be minimized to avoid disruption of the traffic flow.  It is vital that the aviation authorities have the best tools available to quantify current pavement condition, anticipate future problems, and select and schedule the best repair strategy at the proper time. Modern computer systems combined with technologically advanced pavement evaluation and management software can provide the aviation authority with the necessary tools to maximize pavement condition while minimizing costs and traffic disruption.
