Guidance for structures over active airport taxiways

Bridge structures over taxiways are becoming more common at large airports. DEN, SEA, and LGA all have bridges that are complete or under construction. There is very little guidance on structures, fire codes for aircraft fueling in vicinity of the bridge, and clearances for OFA and TSA, particularly vertically. Would like to help develop some guidance, in particular with fueling and vertical clearances, and faa required... more »

Rapid Setting and Durable Concrete Overlays for Airfield Pavements

Concrete overlays are a growing trend in pavement maintenance and rehabilitation. Rapid-setting concrete overlays offer the potential or reopening aprons, taxiways and runways quickly. The viability and durability of rapid setting concrete overlays over asphalt or concrete airfield pavement should be evaluated and tested in order to provide airports and consultants with suitable practice guidelines.

Optimizing Airfield Snow Removal

"The objective of this project is to research best practices focused on managing the resources at airports to optimize the number of runways and taxiways that can be kept open during winter storms. The guidelines should include using process optimization to reduce variation caused by unpredictable weather events and computer simulation analyses to optimize the number of equipment needed, resources required, and optimize... more »

Subsurface Drainage System Benefits in Airport Pavement Performance

This research would summarize the best of practices through survey of airports and consultants; evaluate the effectiveness of subsurface drainage configurations by investigating field performance of airport pavements with and without drainage features; quantify the cost and benefits of including subsurface drainage by comparing any potential extension in service-life with increased construction and maintenance costs;... more »

Expanding in-place cold recycling for flexible airfield pavement

Cold In-place Recycling (CIR) and Full Depth Reclamation (FDR) are two economically and environmentally friendly methods of rehabilitating asphalt pavements. While there is a brief mention of FDR in FAA AC 150/5370-10H and AC 150/5320-6F, it is quite limited and there is no mention of CIR, therefore, this project looks to provide comprehensive guidance as to when CIR and FDR can be used, the materials that can be used,... more »

Estimating the Cost of Hazardous Waste Material Removal for Airport Construction Projects

To develop a comprehensive resource on the safe handling and cost effective removal of hazardous waste material during airports projects. The report will examine ways to identify the waste, evaluate its impact on environment, construction cost and schedule. The report will augment existing industry standard guidelines established by EPA.

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 »

Infrastructure condition assessment using mobile devices

Current methods of assessing the condition of airport pavement and infrastructure typically require restricting access or use, closing, and/or using expensive assessment methods or tools. Technology integrated into most mobile phones (gyroscopes, accelerometers, cameras, etc.) can be used to automatically collect and wirelessly transmit infrastructure-related data to a central database providing real-time tracking of... more »
