The investigation was conducted to evaluate XM20 aluminum landing mat fabricated by Dow Chemical Company, Madison, Illinois. The mat, fabricated from 2- by 12-ft extrusions, was similar to AM2 mat except for minor differences in the cross section of the mat and the method used to attach the end connectors to the mat extrusion. A test section consisting of one clay subgrade item atat a strength of 4 CBR was constructed and surfaced with the 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.
