ABSTRACT
The accelerated pavement testing (APT) program at KansasStateUniversity (KSU)has been active for over 14 years. The sixteenth full-scale pavement test is now complete and the seventeenth and eighteenth experiments are underway. The APT machine is located at the KSU Civil Infrastructure Systems Laboratory (CISL) in Manhattan, Kansas. The equipment was designed and fabricated by an industrial partner, Cardwell International, Ltd. under a grant by the Kansas Technology Enterprise Corporation (KTEC). The building housing the APT facility was made possible by private donations from alumni of the KSU College of Engineering. Shortly after the APT facility was placed in service, the Midwest StatesAccelerated Pavement Testing Pooled Funds Program, a consortium of the departments of transportation of Iowa, Kansas, Missouri, and the Nebraska Department of Roads, was formed with the Kansas Department of Transportation (KDOT) as the lead agency. The technical advisory committee of this program selects and funds the projects at this facility. The 16 projects that have been conducted thus far are:
– APT 1: Rutting of cold in-place recycled, fly-ash stabilized base with a thin asphalt overlay.
