Abstract:

A study was conducted by the USAF Engineering and Services Laboratory to evaluate the rutting effects of high pressure tires on Marshall and gyratory designed pavements. Full scale pavement test sections were designed and constructed at Tyndall AFB and trafficked with approximately 10,000 passes of a simulated F-15 aircraft. A complete loading history of each test section was analyzed. The loading data was analyzed to determine representative loading conditions for each test section. The pavement response data was analyzed to determine representative damage conditions. Statistical analysis techniques were used to investigate variations in response and correlate loading and pavement properties to damage. Conclusions have been developed concerning the effect of pavement mix design on performance. Recommendations have been made for the design of airfield surface layers.
