Figure 11-2. - F11 AM-2 full-length pallet.
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 ofContinue Reading
