dc.description.abstractAbstract:An airfield pavement investigation was performed in January 1994 at Yap International Airport, Yap Island, Federated States of Micronesia, to determine the causes of premature pavement failures. Field testing included a pavement condition survey, dynamic cone penetrometer (DCP) tests, in situ water content measurements, and a drainage investigation. Laboratory testing included gradation and asphalt content tests on the asphalt concrete, and sieve analysis, Los Angeles Abrasion, Atterburg limits, and soaked CBR-moisture-density compaction test on the select fill materials.Results of the evaluation found the pavements structurally inadequate to withstand the current traffic of the B-727-200. The cause of the poor condition of the pavements and the increasing failures are due to water in the base course. The base course material does not meet Federal Aviation Administration specifications because of too many fines passing No. 200 sieve and the plasticity index of the fines being too high. When water enters the base course, the California Bearing Ratio strength decreases from approximately 100 to 15. A clogged edge drain at Sta 37+00 probably accelerated the pavement failures by offering a ready supply of water to the base and select fill material. Recommendations for both short and long term repair of the airfield pavements are presented.en_US
