Airport Pavements
As a leading transportation infrastructure company, we provide a comprehensive range of engineering information, investigations and consultancy services for airport infrastructure.
Pavement Management Services (PMS) undertake a range of geophysical and non-destructive investigations of airfield pavements to provide a full suite of information regarding their construction and condition.
We offer a range of geophysical and non-destructive investigations for airfield pavements. We collect data regarding the construction and condition of the pavement asset. This data is then utilised to conduct engineering analysis and prepare reports which assist our clients to focus repair activities and deal with asset deterioration in a timely and carefully-targeted manner.
Pavement Management Services own and operate equipment capable of Visual Pavement Condition Capture, Pavement Laser Data, Structural Assessments (PCN, Failure investigations), Pavement Structure Assessments, Friction Surveys.
In 2019 the ICAO announced a proposed addendum to the ACN/PCN reporting system that includes a structural rating methodology based on mechanistic principals in efforts to align the rating system with the current design procedures rather than archaic empirical methodologies and increase in aircraft weights and tyre pressures. The new reporting system - termed Aircraft Classification Rating/Pavement Classification Rating (ACR/PCR), is further endorsed by CASA planned to be introduced before November 2024.
So what does this mean for you?
In some cases, the PCR will be transition based on the fleet mix and adopted from calculated ACR (critical aircraft). For aerodromes that cannot determine the basis of their current PCN, the transition will require professional assistance – typically involving pavement investigations and engineering. PMS’ solution adopts ‘state of the practice’ methodologies using invasive and non-destructive testing to analyse the pavement and subgrade material properties (now classified according to modulus rather than CBR), to form an understanding of the engineering properties that cannot be determined from visual or geotechnical testing alone. Employing our strategy to a pavement strength assessment is at the fore front of pavement engineering including pavement strength ratings, works programming, rehabilitations and treatment designs.
We tailor our service to your requirements, selecting from any or all of the following:
ACN / PCN (ACR/PCR) Assessments
Back analysis of deflection bowl data
Layer Moduli and Estimated Subgrade CBR
Residual life of airfield pavement
Increased load capacity (assessment)
