3. The final grading operation must be adequately
level so mats, when laid, do not vary more than l/4inch
in height over a 12-foot distance.
4. Hand raking is necessary to remove small rocks
and other debris that would hinder this task as well as
the connecting of mats.
5. The overall field configuration must be staked
out in its entirety. Accurate longitudinal and transverse
center lines must be established to ease the staging of
the pallets. When no guide rail is used, both lateral
runway edges must be accurately marked to ensure
smooth linear edges from which to lay the mat field. The
line for the edges of the runway is determined by using
a transit and marking them clearly with a chalk line or
stakes. This type of survey is also required when
taxiways and parking areas are installed. When a guide
rail installed, only the center line of the guide rail is
established by transit.
NOTE: Site preparation may not be required if
there is an existing concrete or asphalt runway because
matting can be laid over the existing hard surface.
Under combat/contingency operations, pallets
must be staged in a manner to keep manual handling
to a minimum. Additionally, staging should maximize
all available equipment and manpower coupled with
consideration for the climatic conditions in which the
construction is started
Different methods are used for the staging of
pallets. The most efficient method is the staging of
