This is a technical specification document detailing pavement recess design requirements for an Air Force aircraft tiedown installation. The specification establishes design standards for the static ground surface surrounding an aircraft tiedown eye, requiring the top of the static ground to be set at pavement grade or no more than 6 millimeters (0.25 inch) below grade. A smooth, rounded-edge recess measuring 75 millimeters (3 inches) wide and not exceeding 150 millimeters (6 inches) in length must be provided in the pavement around the tiedown eye to facilitate accessibility and attachment of grounding cables.

The accompanying profile diagram illustrates the Air Force aircraft tiedown configuration with specific dimensional requirements. Key specifications include a minimum slab thickness of 254 millimeters (10 inches), placement of tie dowels as indicated in aircraft technical orders or facility requirements documents, minimum distance requirements of 914 millimeters (3 feet) from tiedown center point to any undoweled joint, bar material specifications using ASD 6620H steel, and provisions for dowel rod installation in preexisting slabs when required for static grounding. The design accommodates anticipated uplift forces for 17,100 kilogram aircraft with minimum pier dimensions of 1.83 by 1.83 meters. Pier design for asphalt pavements must account for anticipated uplift forces, and existing slabs require installation of 38-millimeter dowel rods centered at half slab depth on all four sides with specified minimum anchor block dimensions.
