The study was conducted to evaluate the effectiveness of a membrane-encased soil layer MESL base course under medium-duty landing mat when subjected to C-141 aircraft loading. A special test section consisting of five test items was constructed and trafficked. Test item 1 was considered a control item and was designed to support about 1000 coverages of the C-141 aircraft loading. The design was based on current criteria for airfields surfaced with medium-duty mats. Items 2-5 were designed for MESL base courses of reduced thicknesses. The test included both XM18 and XM19 mats. The test section was subjected to traffic with one main gear of a C-141 aircraft assembly twin-tandem assembly loaded to 146,000 lb.
