“…A finite element model (e.g. approach in reference Doyle et al, 2014) could enhance determination of the critical location and magnitude of limiting stresses/strains and improve effectiveness of the investigation.…”

“…The equations showed strong correlations to the measured data in terms of passes and deformation but were only applicable when the subgrade CBR, mat type, and applied load were similar to the testing conditions. In Doyle et al (2014) compared stress predictions using FE methods to those measured from earth pressure cells installed in full-scale test sections described by Gartrell et al (2009). The authors found that FE showed potential for improving the ability to predict damage to the subgrade and mat system; however, more information from full-scale testing was required to further calibrate the model.…”

“…Full-scale instrumented test section data for two of the matting systems evaluated in this paper and mats tested by Anderton and Gartrell (2005) were included in the Gonzalez and Rushing (2010) data set. Doyle et al (2014) performed three-dimensional finite element analysis (FEA) on instrumented test sections described by Gartrell (2007) and Anderton and Gartrell (2005) using measured EPC data.…”

“…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). Note that (Doyle et al, 2014;Berney et al, 2006) and , although determined using different back-calculation methods, are conceptually the same term and aim to characterize the matting panels' resistance to deflection. The remainder of this section describes each matting system separately.…”

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.

Mixedgrass vegetation is tolerant to a short‐term but not season‐long access mat use during mitigation of industrial traffic

Grasslands are impacted by many disturbances, including energy development. While temporary working platforms using access mats to support large equipment can minimize soil disturbance, less is known about matting impacts on grassland vegetation.We assessed heavy traffic effects on sandy and loamy Mixedgrass Prairie in southeast Alberta, Canada, where traffic occurred in 2015 either directly on grassland or on temporary matting. Vegetation was assessed in 2016 and 2017. Treatments varied in type (with/without matting), timing (spring vs. fall vs. season-long) and duration (6 vs. 12 weeks, and 24 weeks for season-long) of occurrence. While grass biomass was unaffected by direct wheeled traffic, native forb biomass declined, particularly during the first growing season; 1 year later, plots with prior long-term matting had more native forbs. Where traffic occurred on mats, grass biomass decreased when mats were placed for 6 or 12 weeks in spring, or for the entire growing season. Longer mat use also increased introduced forbs, which were positively associated with soil nitrogen supply rates. Plant biomass changes from matting (less grass, more introduced forbs) were more apparent in loamy-sand than loam soils. Overall, while direct traffic had limited impacts on vegetation, matting was more likely to alter vegetation, particularly when placed in spring or for longer periods, and further varied with ecosite type and the timing of traffic disturbance. We recommend that access mats be limited to placement for short periods (≤12 weeks), preferably in falling, to conserve mixedgrass prairie, while longer placement intervals be avoided.
