Performance prediction relationships for AM2 airfield matting developed from full-scale accelerated testing and laboratory experimentation

Abstract: The AM2 airfield matting system is used by the U.S. military for temporary, rapidly constructed airfields. Predicting the number of allowable aircraft passes across an AM2 installation is challenging because of the complex design of the joining system and the fatigue behavior of the joints. Prior to this work, the prevailing methods used to predict the performance of AM2 were based on the CBR design procedure for flexible pavements using a small number of full-scale test sections over CBRs ranging from 4 to 10… Show more

“…The full-scale test data used for calibrating the performance model are from the RPRE program, which conducted tests using F-15 and C-17 load carts on AM2 mats over Buckshot clay test sections of various subgrade CBR (12)(13)(14)(15)(16). A CBR value of 6 is the lowest subgrade stiffness used during the full-scale testing, so the authors used permanent deformation equations produced by Rushing (17)(18)(19) for the F-15 and C-17 aircrafts. The predominant failure mechanism at low CBR values is permanent deformation.…”

“…The reason for choosing these particular equations is that the primary failure mode of airfield mats over low subgrade CBR under aircraft tire pressures is permanent deformation, not mat breakage. The equations are from Rushing and Howard (17)(18)(19).…”
