AM2 Mat End Connector Modeling and Performance Validation
Abstract
The U.S. Army Engineer Research and Development Center executed a test program for the Air Force Civil Engineer Center and the Naval Air Systems Command that involved a series of full-scale tests of the AM2 airfield mat system in an effort to validate a model that can predict the performance of AM2 under different operational conditions. After completion of the program, a thorough investigation of both the subgrade and the mat revealed that the manufacturer s drawing of the extrusion dye for the AM2 end connector omitted fillets in the corners of the locking bar channel. The efforts of the test program discussed in this report focused on evaluating AM2 with the two different end connector designs (i.e., filleted and non-filleted locking bar slot) and evaluating the performance of each in terms of number of passes to failure. Two sections were tested individually under simulated F-15E aircraft traffic. Mat breakage and permanent deformation were monitored. The AM2 end connector design with the filleted corners was able to sustain more than twice the traffic sustained by the non-filleted design before failure by both permanent deformation and mat breakage.
