4. TRAFFIC VOLUME. The traffic type, volume, and pavement design life are essential inputs to the
pavement design procedure. Determine the total number of passes of each aircraft type that the
pavement will be expected to support over its design life. The minimum design life for Navy and Marine
Corps facilities is 20 years. Only aircraft departures are normally included as passes in pavement
thickness design. The exception to this is in touchdown areas on runways where the impact due to
aircraft performing touch-and-go operations will cause pavement damage. On pavements that are to be
used for touch-and-go operations, add the expected number of touch-and-go operations over the design
life to the number of departures to arrive at the design traffic. Obtain data for the specific Navy and
Marine Corps airfield facility under design to forecast aircraft traffic operations over the design life of the
pavement. When site-specific traffic projections are not available, the traffic pass levels listed below are
the minimum pass levels to be used in design.

5. ROLLER-COMPACTED CONCRETE PAVEMENT. Roller-compacted concrete pavement (RCCP)
is a rigid pavement and can be used as pavement except for runway and high-speed taxiway pavements
for fixed-wing aircraft. RCCP can be used for all helipad and heliport pavements.
6. RESIN MODIFIED PAVEMENT. Resin Modified Pavement (RMP) can be used as an Navy
pavement except for fixed-wing runways and high-speed taxiways. RMP can be used for helipads and
heliport pavements and for both rotary-wing and fixed-wing parking aprons.

PAVED SHOULDERS.
a. Location. Paved shoulders should be provided for airfield and heliport construction as
designated in EI 02C013/AFJMAN 32-1013/NAVFAC P-971.
b. Structural Requirements. As a minimum, paved shoulders shall be designed to support a load
of 4,535 kilograms (10,000 pounds) imposed by a single wheel with a tire pressure of 0.69 MPa (100
psi).
8. PAVEMENT DESIGN POLICY. The Navy recognizes PCASE rigid and flexible pavement design
programs and consensus industry standard programs in addition to the traditional Navy rigid pavement
design program. Designers are encouraged to consider life cycle costs when designing new pavements.
When the life of the pavement can be extended by more than 10 times, it is acceptable to increase the
pavement thickness by 1 inch or less as determined by the Navy's traditional rigid pavement center
