18 Contingency Operations PQS Question Describe the duties of the following Rapid Runway Repair (RRR)/ Airfield Damage Repair teams and state what type of equipment is necessary to perform their mission under Battle Damage repair (BDR)/RRR. [ref.a, ch. III] a.MOS [Annex C] b.DAT [Annex] c.Crater/Spall [Annex E,F]

19 (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).

20 MOS Team MOS Selection Team (Primary & Alternate) Team Chief Selector Plotter Communicator Battalion Liaison Officer OIC AOIC

21 MOS Selection Team 1 – Receives information from damage assessment teams 2 – Plot ALL damage on runway map 3 – Maintain Status Boards 4 – Select new runway location 5 – Determine size of new runway 6 – Determine quality of repair for craters in new MOS

25 Explosive Ordnance Reconnaissance Report Type & Location Grid Coordinates Radiological Results Descriptive information Detailed Drawing of UXO ELEVATION VIEW CLOCK METHOD

26 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

27 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.

34 106 Contingency Operations PQS Question Describe the following methods of RRR/ADR: a.Folded Fiberglass Matting b.AM-2 aluminum matting c.Crete mobile

35 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.

36 Fiberglass Reinforced Plastic FOD Covers Folded Fiberglass Matting Two patches per kit ¼” thick 6’ wide, 30’ long 30’ x 54’ patch – bolted together 60’ x 54’ patch Tow into position Anchor Leading and Trailing edge only Do not store in direct sunlight Can be used as flush finish Used primarily on runway and taxiway

37 Fiberglass Reinforced Plastic FOD Covers Bolted Fiberglass Matting (FRP) Air shippable 8’x 8’x 20’ ISO container 1/4” – 3/8” thick 4 small patches or 1 large patch per container Tow into position All tools contained in each kit Do not store in direct sunlight Can be used as flush finish Used primarily on runway and taxiway Average weight 2,144 lbs One small patch is 32’ x 32’ 9” One large patch is 62’ x 69’ 4”

38 AM-2 Aluminum Matting Hand-assembled and anchored over the crater which was prepared with a layer of crushed stone. This repair surface is the most manpower intensive of the two primary ADR techniques

39 AM2 Aluminum Matting

40 AM-2 Aluminum Matting Primarily used on taxiway and parking apron 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

41 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.

42 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

43 Crushed Stone Repair Diagram

44 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.

45 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

46 106Contingency Operations PQS Question Explain the fundamentals of a typical Battalion tent camp layout.

47 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

48 Tent Camp Layout Sanitary –Water supply –Drainage –Shade –Access –Site not occupied by other units in last two months

49 Tent Camp Layout

50 Camp Maintenance Inspections –Controlled inspections –Operator inspections –PM inspections

51 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.

52 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.

53 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.

54 Camp Maintenance These inspections occur before, during, and after operation of the equipment. Operator inspection of constantly used equipment is another form of PM.

55 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.

56 106 Contingency Operations PQS Question Explain the purpose of maintaining operators logs for generators and boilers [ref. c]

57 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

58 Ground Rods –Grounding protects human life, the generator, and the distribution system –Provides a path for electrical current to earth

59 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
