Airfield RAP survey to aid research

​​​​

The Airport Asphalt Pavement Technology Program (AAPTP) is conducting a project to develop standards to optimize the use of reclaimed asphalt pavement (RAP) in all layers of airfield asphalt pavements while maintaining performance expectations and aligning with national and industry environmental goals.

An early task in this process is to identify airports that have used RAP in asphalt mixtures in runways, aprons, or other airside pavements.

Complete and submit this survey by Nov. 6

The research plan includes both the University of Nevada Reno and Auburn University conducting robust laboratory study to predict impacts for using RAP in P401 mixtures. Additionally, the team will be comparing performance after construction as the material properties contribute significantly. Samples of P-401 mixtures are being collected and evaluated for cracking resistance, FOD potential, and other mixture properties.

However, a population of mixtures placed in real-world environments is needed to evaluate trends. The survey aims to identify projects and locations that may have used RAP in a P-403 mixture, P-401 mixture, or in other mixtures known to be placed in airfield runways, taxiways, parking aprons, or other airside facilities.
