Changes to the RCAM have impacted how and when airports remove contaminants on the runway and in turn has impacted the hours needed for personnel and equipment to remove contaminants as well as the useful life of markings and pavement surfaces.
This synthesis would analyze the current state, feasibility, and interest of airports and the FAA to use recycled concrete aggregates as constituents in a concrete mix design of new airfield rigid concrete pavements.
In recent years, there has been an a growing concern regarding emissions of aviation related ultrafine particles (UFPs). This effort would consolidate relevant research regarding aviation and UFP emissions in order to provide useful insight to airports, stakeholders, and the public.
To compile data from various airports around the country about practices they use for airport credentialing. This would also include the setup and staffing of an airport credentialing office.
To receive the full potential of perimeter fencing, the fence needs to be extended underground. Wildlife can push the bottom of a chain link fence up or dig under to enter onto properties and cause delays or damage. Animal barriers that can interlock with chain link fencing to extend and secure the fence have proven to be very effective. Dig Defence, LLC has a proprietary solution for these issues.
Runways routinely require the removal of rubber to maintain adequate surface friction. According to FAA AC 150/5320-12C, rubber can be removed by High-Pressure Water, Chemical, High-Velocity Impact, and Mechanical removal. Survey experiences with various airports in different climates to assess the cost, time required, benefits, and tradeoffs with various methods of rubber removal.
The synthesis will serve as a useful reference document for presenting data and informing policymakers, seaplane operators, regulators,... more »
