2-18.104.22.168 AM-2 can be assembled as a crater cover that is usually 16.5 meters wide by
23.6 meters long (54 feet wide by 77.5 feet long), or as a FOD cover, to extend a
parking ramp whose dimensions are limited only by the amount of AM-2 available. The
assembly procedures are similar; however, for specific instructions on how to assemble
a towed patch, see AFPAM 10-219.
2-22.214.171.124 Assemble the matting from right to left in the direction in which the mat will be
placed. You can assemble this matting using all full mats (3.65 meters [12 feet]) or a
combination of full and half (1.83 meters [6 feet]) mats. A standard bundle of AM-2
contains 11 full-length mats and two half-length mats; both will be described since every
piece of mat will be needed.
2-126.96.36.199 Position the first piece of full mat so that the left end of the mat has the
prongs facing up. Position the second full mat so that the right end of the mat prongs is
facing down. The prongs of both mats should join together. To increase stability and
lock the mats together, insert a flat locking bar into the rectangular slot formed where
the end prongs are joined. Continue this process across the full width of the assembly.
The only exception is the last piece of mat; use a half mat instead of a full mat.
2-188.8.131.52 The second row is placed similar to the first except it is started with a half mat
first. Before placing each mat into position, make a quick check of the prongs for
debris. Use a broom or brush to remove dirt and stone that might prevent the mat from
joining together. As each mat is positioned, install the locking bars.
2-184.108.40.206 The mats are designed with a loose fit that allows for expansion; therefore, it
is possible to have a row of mats installed so misaligned as to prevent the proper
engagement of follow-on rows. Using locking bars as temporary spacers between the
rows can normally prevent this condition. Place a locking bar on edge where the ends
of two mats join and at the row ends. After three or four rows have been laid using
locking bar spacers, remove the spacers further away and use them on the row that has
just been laid. These locking bar spacers are commonly referred to as "T" spacers.
2-220.127.116.11 Use extreme caution in adjusting the mat; always place a wooden block
against the mat edge. Strike the wooden block and not the mat. Sledgehammer blows
against the edge of the mat can deform the edge enough to make it impossible to
connect the next row of mats.
2-18.104.22.168 Ramps have been developed to ease the transition from the pavement
surface onto the mat. Start at the right corner of the assembled mat to connect the first
ramp. Place the next ramp so that the holes in the overlapping plate are aligned with
the threaded inserts on the ramp just installed. Fasten with flat-head screws coated
with anti-seize compound. Use locking bar spacers between the mat and the ramp to
keep it properly aligned.
2-22.214.171.124 After all ramps are placed and screwed together, use the ramps as a template
