“…FEA modeling was recommended as a preliminary tool to be used prior to full-scale testing. Rushing and Howard (2015) developed an empirical method for characterizing rutting resistance of the AM2 mat system. Data collected from full-scale testing of AM2 over five subgrade strengths (CBRs of 6 to 100) were used to develop correlations between subgrade soil deformation rate, number of applied F-15E passes, and underlying soil's CBR.…”

“…Of the methods discussed thus far, those by Rushing and Howard (2011;2015) are the most directly applicable to this paper. Rushing and Howard (2011) developed an empirical technique for predicting surface deformation and furthered their analysis by using instrumentation measurements, but the study focused on matting for roadways.…”

“…Rushing and Howard (2011) developed an empirical technique for predicting surface deformation and furthered their analysis by using instrumentation measurements, but the study focused on matting for roadways. Rushing and Howard (2015) used full-scale data from simulated F-15E traffic tests, but limited their study to AM2 and did not incorporate measured earth pressure for relating mat modulus to confinement provided by the system. Components of both of these approaches were adopted for the analysis presented in this paper.…”

“…The overall composite modulus in absence of a joint ( ) is currently the most reasonable measure available to the authors 7 for each mat's elastic properties. Rushing and Howard (2015) published flexural properties for Mat 1, but they were not used for the analyses presented in this paper for consistency with information available for the other mats. was determined using the back-calculation procedure described by Gonzalez and Rushing (2010) and the test setup described by Berney et al (2006), where a single panel was simply supported and loaded incrementally while deflection was measured at four locations (similar to a four point bending test).…”

This paper presents results from full-scale testing of six airfield matting systems of various materials and designs that were evaluated on subgrades constructed to a California bearing ratio (CBR) of 6 and subjected to simulated aircraft loads. Mat breakage, deformation, and subgrade earth pressure were monitored during each test to determine the effectiveness of the airfield mats in reducing cumulative subgrade deformation and decreasing subgrade stresses.Based on test results, a simplified expression was developed to predict subgrade deformation on a CBR of 6 as a function of aircraft passes and airfield mat properties. The values predicted showed reasonable correlation with the measured data. The empirical equation can be used as an expedient tool for characterizing airfield matting behavior.

“…A basis for this is provided by Garcia and Howard (2016), where the authors developed relationships for predicting subgrade deformation for different mat systems as a function of mat stiffness and F-15E passes. Rushing and Howard (2015) and Rushing and Howard (2017) performed similar work for the AM2 mat system for a range of CBRs. The test program is encouraging for performing additional investigations on different soil conditions.…”

The U.S. military began using remote piloted aircraft (RPAs) for reconnaissance and offensive operations in the mid-1990s. Their effectiveness has led to the development of several new airframes with increasing capability and operational requirements. RPA ground movements are ideally separated from manned aircraft traffic areas with their own parking aprons and hangar facilities. For expedient construction of RPA facilities, a matting system is desired to rapidly create parking aprons and hangar flooring. This report describes the evaluation of four commercially available airfield matting systems that were investigated to determine their capabilities for supporting RPAs and support vehicle operations. Each mat system was tested on a full-scale test section consisting of a subgrade with a California bearing ratio (CBR) of 6 surfaced with the airfield mats. Simulated MQ-9A Reaper and P-19 fire truck traffic was applied to the mat surface. Mat breakage and deformation were monitored and compared to performance requirements for compliance. Recommendations were provided for each mat system based on suitability and risk to aid in future procurement decisions.
