Airport best practices to minimize catalytic oxidation of carbon brakes

To support the air transport industry's holistic effort to reduce maintenance costs and safety risks, research is needed to identify airport best practices that could reduce the influence of airfield pavement deicing on accelerated structural deterioration of aircraft carbon brakes and provide guidance to airports on selection and application of these best practices.

Antimicrobial Formulations to Reduce Mold Intrusion on Airfield Markings and Pavements

The reoccurring growth of mold and continued maintenance required to prevent discoloration of airfield paint markings poses a continued problem that draws money that would otherwise be used for pavement improvements. This research will employ recent innovations in antimicrobial research to develop a quaternary ammonium compound that can be applied as a top-coat to markings and pavement surfaces whereby the modified surface... more »

Enabling Airports to be ACR/PCR Compliant - From Design to Implementation

The new (Aircraft Classification Rating) ACR- (Pavement Classification Rating) PCR pavement strength reporting method is to be implemented by the International Civil Aviation Organisation (ICAO) and airports around the world are working towards ensuring that their airports are complying with the new requirements. For airports in developing countries and local airports, this can be challenging due to the availability of... more »

Evaluating the Impact of Aircraft Lateral Turning Forces on Pavement Design and Performance

This research would help airports understand, qualify and quantify lateral shear forces within the surface or subsurface layers of flexible pavements induced by landing gear lateral turning movements; develop models to take the excessive lateral shear forces into consideration in the design of runway asphalt concrete surface layers; formulate recommendations to include shear resistant asphalt concrete layer (or sublayer)... more »

Real Time Airside Infrastructure Maintenance Evaluation and Hazard Detection

Airside infrastructure maintenance requirements are typically defined
using passive sensors that detect surface phenomena only, or using
devices that require slow or stationary equipment which affect capacity
& delay and may even require NOTAM closures for in-depth
evaluations. A need exists to streamline the evaluation process to
provide real time input to aircraft operations and progressive
infrastructure maintenance... more »

Construction sequencing best practices for airports

New construction and renovation projects at airports experience cost and schedule constraints due to the unique operational aspects and differing facility types. For example, apron expansions must give heed to airside operations and terminal renovations of retail space must often take place overnight when passenger traffic in minimal. This research will investigate state of the art techniques to enhance construction sequencing... more »

Selection and Application of Building Materials for Passenger Terminals

To create a comprehensive resource for architects, interior designers, engineers and airport operators to help them in selection of these materials for new construction or renovation of existing facilities. The guidebook should also provide guidance to airport operators and designers on how to evaluate life cycle cost implications of selecting different building materials.

Improving the Durability of Concrete Pavement Surfaces through Improved Specifications and Testing

The objective of this research is to provide recommended improvements to the current P-501 specification along with recommendations for improved paving practices to enhance or insure the durability of the concrete surface. This project will identify major airports that are experiencing durability issues, measure the scale of the issue through field inspections, and conduct a petrographic examination of the concrete materials.... more »
