A Pavement Evaluation Team from HQ Air Force Civil Engineering Support Agency (HQ AFCESA) conducted a nondestructive, structural pavement evaluation at King Salmon Airport, Alaska, during 7-12 August 1991. The analysis indicated the pavements overall are structurally capable of handling the current level of aircraft traffic. Exceptions are the southeast touchdown area on the Runway, which is only likely to last 5 to 10 years, and the Transient Apron and access taxiways, which are overloaded by moderately to heavily loaded C-141, C-5, and KC-135 aircraft. Taxiway E on the civilian side is also very weak. Additional discussion regarding weak pavement features is provided on pages 14 and 15. The Allowable Gross Load Table contained in Appendix F of this report gives detailed information on allowable aircraft weights for given traffic volumes on each pavement feature. A separate list of AGLs is provided for use during the spring thaw. Most of the airfield pavements are in GOOD to VERY GOOD condition based on surface distresses. The most significant problem is cold temperature cracking of the asphalt pavements throughout the airfield. The cracks are generally well maintained, which is one reason for the high condition ratings of many features. For all asphalt paving projects, it is very important that the proper grade of asphalt cement be specified. Otherwise, premature cracking will occur during winter. Guidance is provided in Section VI of this report on selecting asphalt cement for cold regions. Also, the joints and cracks need to be resealed within one or two years for virtually all of the PCC pavement features, along with spall repairs and an occasional slab replacement in some areas.
