17 -- LIGHTWEIGHT AIRFIELD SURFACING FOR THE EXPEDITIONARY AIRCRAFT SOL N68335-96-RFI-605 DUE 031296 POC J. Fackenthal Code 213, (908) 323-7423. The Naval Air Warfare Center Aircraft Division Lakehurst (NAVAIRWARCENACDIVLKE) New Jersey is soliciting proposals from offerors to provide an off-the-shelf item, or design and furnish a product, to meet the capabilities for a lightweight airfield surfacing system for the Expeditionary Airfield (EAF) program. This lightweight mat must provide a bearing surface on subgrades for all airfield expanses (i.e. runsways, taxiways, parking areas, etc), including vertical Takeoff and Landing (VTOL) Pads. The surfacing system may be fabricated from lightweight metal, plastic, composite, or any combination of these materials, provided that the lightweight mat has the following range of capabilities: a. Packaging Properties: (1) The lightweight airfield surfacing system must be compatible with the International Organization for Standardization (ISO) container system. An ISO flatrack with external dimensions of 8''W x 4.25'H x 20'L, must provide a minimum of 12,500 sq ft of runway surface area, and will not exceed a payload weight of 38,600 pounds. (2) The lightweight mat must be packaged in packages that are suitable for stacking on the flatrack and shall be readily assembled and disassembled using only conventional tools and packaging materials. (3) It is desirable that these packages be designed so that the packages can be secured on the flatrack to protect against the shifting of packages. (4) The packages must be designed to be loaded and unloaded from the ISO flatrack with a 4000 pound capacity forklift. The loading/unloading shall require no special adapters or fittings. b. Installation Rate: 1. The installation rate must be a minimum of 3500 ft squared per hour for a 16 man team on an eight hour shift. c. Structural Properties: (1) The lightweight mat must withstand sustained ground and air operations of the following aircraft, to include arresting gear operations of applicable aircraft: H-1, UH-1, CH-46, CH-53E, UH-60, MV-22, AV-8B, EA-6B, F/A-18E/F, F-14, F-15, F-16, C-5B, C-17, C-130 and C-141. (2) The lightweight mat must withstand sustained trafficking by support equipment such as fuel trucks, tow tractors, crash-crew trucks, and forklifts. (3) The lightweight mat must withstand impacts from a 9-lb sledge hammer and pry bars, and have the ability to have up to 4 1/4-inch holes cut into its surface without loss of structural integrity. d. Subsurface Requirements: (1) The lightweight mat must be easily installed on a minimally prepared surface with a minimum California Bearing Ratio (CBR) of 4, or Airfield Index of 5.75. (2) A mat which is unsupported by the subsoil and is installed in the middle of an expanse must be capable of deflecting into a two inch deep void without suffering permanent deformation to the unsupported mat and the adjacent mats. e. Nonskid Surface Properties: (1) The lightweight mat must have an integral or replaceable nonskid surface with a coefficient of rolling friction of at least 0.8, dry. (2) The nonskid must have a minimum useable life of six years during which the coefficient of rolling friction shall not fall below 0.5, wet. (3) The nonskid must have the ability to be replaceable when worn. Once replaced, the nonskid shall have the same properties as newly manufactured nonskid. (4) The nonskid surface must be impervious to fuels, solvents, and long-term exposure to ultraviolet radiation. (5) The nonskid must withstand applications of mechanical cleaners used to remove rubber buildup deposited by aircraft tires. f. Jet Blast Impingement: (1) The lightweight mat and related hardware, including the nonskid material, must withstand jet blast impingement of 1800 degrees F at 1500 knots and 15psi, with the source at a height of four feet. g. Connector Properties: (1) The lightweight mat panels/sheets must have interlocking connections and be easily assembled. (2) Connector construction must prevent water-laden subsoil from being pumped onto the mat surface, and prevent jet blast or rotor wash from entering under the mat. h. Lifespan (1) The lifespan of the lightweight mat must be a minimum of 20 years. i. Ambient Conditions: (1) The lightweight mat must be capable of being assembled/disassembled in any combination of the following conditions: (a) Poor lighting (0.02 ft-candle); (b) High winds (100 knots); (c) Low temperatures (125 degrees F); (d) High humidity (90%); (e) Rain; (f) Snow. (2) Under adverse ambient conditions, assembly/disassembly of the lightweight mat must require only standard hand tools and minimal installer skills. The installer shall be garbed in cold weather clothing or nuclear, biological, and chemical warfare protective clothing. j. Thermal Ranges: (1) Ambient temperature range is -25 degrees F to 150 degrees F. Ground temperature is -65 degrees F to 150 degrees F. k. Thermal Cycles: (1) The lightweight mat must be able to withstand rapid temperature cycles of up to 140 degrees F in four hours, for air transport to hot climates, without loss of structural integrity. l. Compatibility with AM2 Mat and Accessories: (1) The lightweight mat must be compatible with the existing AM2 mat system so that a smooth transition can be made between the two surfaces. This can be accomplished with adapters, if required. m. Compatibility with EAF Marking and Lighting: (1) The lightweight mat must be compatible with the existing EAF marking and lighting system which requires attachment to the lightweight mat and painting the lightweight mat surface. n. Compatibility with Existing Paved Surfaces: (1) The lightweight mat must be suitable for installation over deteriorated asphalt or concrete surfaces, and for butting-up against existing paving surfaces, or overlapping these surfaces. o. Maintenance and Repair of Mat Expanses: (1) Individual lightweight mat rows in the center of an expanse must be removable using a 10,000 pound rough terrain forklift so that damaged mats and non-RFI mat can be replaced. (2) Damage to the lightweight mat must be repairable. Surface damage can include holes, dents, cracks, and connector damage. This damage must be repairable when the mat is installed or stored under normal and adverse conditions. (3) Materials used for the repair must have a minimum shelf life of three years, and meet OSHA safety requirements for use and storage. p. Toxic Effluence (1) None of the material used in the lightweight mat system shall give off toxic fumes under the normal operating conditions. q. Airfield Vulnerability: (1) It is desirable that the lightweight mat, when installed or stored in a combat area, have a minimum electromagnetic and thermal signature in order to avoid detection. (2) It is desirable that the lightweight mat system resists the effects of nuclear and chemical attack such as pressure, radiation, electromagnetic pulse, and have the capability to be decontaminated from nuclear or chemical fallout.
