(MOS) Minimum Operating
Strip
MOS- The launch and recovery surface selected for
repair is called the minimum operating strip (MOS).
The MOS is the area from which aircraft actually
takeoff and land.
When a MOS is combined with access taxiways from
aircraft staging areas such as shelters and parking
ramps, the entire area becomes the minimum airfield
operating surface (MAOS).

ADR Factors
Aircraft Type and Load. Each aircraft has distinct characteristics
(e.g., wing span, tire pressure, load capacity, braking mechanism.)
Available Material. The type and quantity of material (e.g., backfill,
crushed stone, fiberglass mat) available for a repair.
Available Equipment. The type and quantity of CESE available for
a repair.
Time Constraints. The time allotted to accomplish the repairs before
the first aircraft arrival or departure.
Repair Crew Capability/Equipment/Manpower. The repair
crew’s capacity for the task (e.g., experience, number of repair people,
resource availability).
Type of Damage Sustained
Airfield Damage
Crater: is damage that penetrates through the pavement surface
into the underlying base and subgrade soil uplifting the
surrounding pavement and ejecting soil, rock, and pavement
debris around the impact area. Craters represent much more
severe damage than spalls.
Large craters: diameter equal to or greater than 4.57 m (15 ft).
Small craters: diameter less than 4.57 m (15 ft).
ABFC P-36 RRR – Ref. Manual
Spall: is damage that does not penetrate through the pavement
surface to the underlying layers. Spalls may be up to 1.52 m (5
ft) in diameter.

Cheap crushed stone repair – least expensive
Choked ballast repair – when water is present
• Sand Grid
– Requires FOD cover
– Height of sub-base critical
• Regulated Set Portland Cement
– Batched from ‘Crete Mobile’
– 6” – 12” thick (set in 20 – 30 minutes, 2500 psi in 2 hours)(traffic ready)
• Precast Slabs
– Cold weather climates (European theater)

PQS Question 106.2
Describe the following methods of
RRR/ADR:
a. Folded Fiberglass Matting
b. AM-2 aluminum matting
c. Crete mobile
Folded Fiberglass Matting
This procedure is currently the primary MOS repair method.
It involves the installation of an anchored FFM over a
crater which was prepared with a layer of well-compacted
crushed stone. Crater preparation is essentially identical to
that used with the AM-2 matting system. Again, this is the
principle method of ADR employed for MOS repairs.
The FFM is air-transportable, can be moved easily by
vehicles, can be positioned at greater distances from
airfield pavement surfaces, and must be stored indoors out
of the elements.

stone. This repair surface is the most
manpower intensive of the two primary
ADR techniques

Package contains matting, tools and accessories to
assemble 54’ x 72’ FOD cover
5 boxes contains 9 bundles of AM Matting
Can be towed from side to side
Must be centered on the taxiway
AM2 patch is 54’ x 77’
Must be towed by two pieces of like equipment
AM2 Matting cannot be a flush repair
Crushed Stone Repair
• Clear debris from the crater perimeter.
• Determine the actual crater diameter versus the apparent
crater diameter, i.e., the extent of crater pavement
damage/upheaval.
• Remove the up-heaved pavement.
• Remove large objects 36” or larger and water from inside
the crater, as required.
• Backfill the crater with ejecta, ballast rock, or clean fill.
• Backfilling the crater with crushed stone.
• Compaction of the crushed stone.
Crushed Stone Repair
• Install a 12” layer of crushed stone over the backfill
material.
• Compact the crushed stone material in lifts approx 6”
thick.
• Compact each lift of crushed stone using a minimum of
four initial passes of a single-drum vibratory roller
• Final compaction with 28 passes
• Roll done parallel to runway
• For every inch above runway surface 3’ taper required
Crushed Stone Repair
Diagram
Crete mobile
The trailer-mounted crete mobile carries the cement,
sand, and coarse aggregates in divided bins on the
unit.
Sand and aggregates are proportioned accurately by
weight or volume with cement mixture and water
and mixed.
The mixing process will proceed until the aggregate
bins are empty.
Material feed to project can be stopped and started at
any point to allow finishing crews to continue at a
steady pace.
Pavement
Asphalt Pavements. Anchoring in asphalt pavement requires
a 9.5-inch bolt and polymer. A hole 10 inches deep and 1.5
inches in diameter is drilled at the center of each predrilled
mat hole. A two-part resin polymer is mixed and poured
into each hole to about 0.5 inch below the surface of the
pavement. An anchor bushing and bolt are immediately
placed into each hole and pressed firmly (standing on the
bolt and bushing) against the mat. The polymer will harden
in about three minutes. Unless extra people are available,
there may not be time to drill all the holes before beginning
to pour the polymer

PQS Question 106.3
Explain the fundamentals of a typical
Battalion tent camp layout.
Tent Camp Layout
• Tactical
– Sufficient space for command dispersion
– Concealment from ground and air
observation
– Protection from bombing and strafing
attacks
– Protection from mechanized attack
Tent Camp Layout
• Sanitary
– Water supply
– Drainage
– Shade
– Access
– Site not occupied by other units in last
two months
Tent Camp Layout
Camp Maintenance
• Inspections
– Controlled inspections
– Operator inspections
– PM inspections
Camp Maintenance
 Control Inspections - A control inspection reviews
all camp facilities to determine the maintenance required
during a deployment to preserve or improve the condition of
the camp structures and property.
 It is the foundation for the camp maintenance program and
workload.
 A control inspection is conducted within the first 30 days of
a deployment.
Camp Maintenance
• Annual Inspection Summary – The AIS
report
documents deficiencies in camp
facilities.
• AIS reports are produced annually.
• Validating deficiencies and costs is important
to justify the money to support the proper
maintenance and repair of camp facilities.
Camp Maintenance
• Operator Inspections –consist of examining and
making minor adjustments.
• Are performed by the operator assigned to the
equipment.
• Are part of the operator's day-to-day
responsibilities.
Camp Maintenance
• These inspections occur before, during, and
after operation of the equipment.
• Operator inspection of constantly used
equipment is another form of PM.
Camp Maintenance
• Trouble Desk attendant receives all customer
trouble calls, enters this information into the trouble
desk log and fills out emergency/service
authorization forms.
• Trouble desk attendant makes sure that ESA
forms are properly routed and that outstanding
ESA’s are completed within the required
deadlines.
106 Contingency Operations
PQS Question 106.4
Explain the purpose of maintaining operators
logs for generators and boilers [ref. c]
Camp Maintenance
• Operators Log
• Daily operating logs are kept on some
Equipment. The main purpose for using
operating logs is to continuously record data
on equipment performance
Ground Rods
• Ground Rods
– Grounding protects human life, the generator,
and the distribution system
– Provides a path for electrical current to earth
Generator Sheltering
• Generator sheltering protects and prolongs the life
of advance-base portable generators
– Protects the equipment from rain, wind, and
other adverse conditions
– Good for noise discipline during contingency
operations
