Federal Aviation Administration Undertakes Major Hma Research for Airfield Pavements

The Federal Aviation Administration (FAA) has undertaken a major hot mix asphalt (HMA) research program for airfield pavements. The Airfield Asphalt Pavement Technology Program (AAPTP) was established in fiscal year (FY) 2004 through a cooperative agreement between the FAA and Auburn University. The program will be funded by the FAA and will be administered by Auburn University. A t o t a l o f...

Modeling of Concrete Airfield Pavements Using Artificial Neural Networks

Airfield pavement design is a decision making process which uses pertinent information available to make required judgments. One of the tools used in the design process is analysis of the pavement system. To be of value, it may be necessary to make many analyses of several pavement systems with different gear configurations and different loading conditions. With the more sophisticated models, s...

ERDC/GSL TR-17-10 "Rutting Performance of Cold-Applied Asphalt Repair Materials for Airfield Pavements"

Cold-applied asphalt mixtures are often used for pavement repair, primarily because of the small quantities involved and/or the unavailability of hotmixed asphalt. These cold-applied mixtures have poorer rutting resistance than hot mix asphalt because additives, often solvent, are required to provide adequate workability for them to be placed at ambient temperatures. This study primarily evalua...

Performance of Dowel Bar Retrofitted Concrete Pavement Under HVS Loading

The California Department of Transportation uses Dowel Bar Retrofit (DBR) as a rehabilitation strategy for concrete pavements. Two test sections were dowel bar retrofitted and a third section was designated for control on US 101 near Ukiah, California. All three sections were subjected to accelerated pavement testing using the Heavy Vehicle Simulator (HVS). The HVS results demonstrated a large ...
