The report describes an investigation conducted to evaluate the performance of a production quantity of XM20 landing mat extruded by Dow Chemical Company, Madison Division, Madison, Ill., and fabricated by Washington Aluminum Company, Enterprise, Ala. The mat, fabricated from 2- by 12-ft extrusions, was similar to AM2 mat except for the method used to attach the end connectors to the main extrusion and a slight change of the cross section of the main extrusion. A test section consisting of one clay subgrade item at a strength of 4 CBR was constructed and surfaced with XM20 mat. The test section was subjected to uniform-coverage traffic representing operations of an aircraft having a 60,000-lb gross weight with a single-wheel main-gear assembly load of 27,000 lb with a 30x7.7 tire inflated to 400 psi.
