OBJECTIVES:

The project scope includes but not limited to the following elements:

Asphalt Pavement Maintenance

Asphalt Crack sealing: The most common types of cracks that are sealed include longitudinal cracks, transverse cracks, reflection cracks, edge cracks and block cracks. Cracks up to 1/8 inch wide need not be sealed. Cracks between 1/8 and 1/4 inch wide should be routed to a width of 1/2 inch, cleaned, and then sealed. For larger cracks one inch or mire in width, pavement should be partially removed to an appropriate width and depth. The crack should be cleaned out and sealed back in place with an asphalt patch. Fatigue (alligator) cracks are seldom routed and sealed individually. Asphalt crack sealant should conform to ASTM D6690. Test the crack sealant material by a government-approved independent laboratory for specification conformance before it is used on a project. Provide backer rod material that is a compressible, non-shrinking, non-staining, nonabsorptive material and nonreactive with the crack sealant. Use backer rod with a melting point temperature of at least 2 degrees C greater than the maximum pouring temperature of the sealant being used, when tested in accordance with ASTM D789. Use material that has a water absorption of not more than 5 percent by weight when tested in accordance with ASTM C509. Use backer rod material that is 25 percent (plus or minus 5 percent) larger in diameter than the nominal width of the crack. The use of backer rod materials in bituminous pavements is to control the routed crack width to depth (W/D) ratio and minimize waste of sealant material. Backer rod material is not required in 20 mm ¾ inch (UFGS 32 01

17.61 Sealing Cracks in Asphalt Paving).

Asphalt Surface sealing:

The bituminous material must be a Gilsonite Modified Asphalt emulsion that meets

UFGS 32 01 13.63. The emulsion must be applied upon the properly prepared, clean and dry surface at the application rate approved by the Contracting Officer foreach designated treatment area. The emulsion temperature must be at a temperature at or above 54 deg C130 deg F, but not exceeding 71 deg C160 deg for in accordance with the manufacturer's recommendation using a pressure distributor to obtain uniform distribution at all points. During all applications, the surfaces of adjacent structures must be protected in such manner as to prevent their being spattered or marred. Bituminous materials must not be discharged into borrow pits or gutters or upon the airport area. Apply the rejuvenator when the existing surface is dry, and when the weather is not foggy, rainy, or when the wind velocity will prevent the uniform application.

Apply the rejuvenator when the atmospheric temperature in the shade is10 degrees C50 degrees

Fand rising or when pavement temperature is above15.5 degrees C60 degrees F and rising, and the temperature has not been below 2 degrees C35 degrees F for the 12hours prior to application unless otherwise directed. Do not apply if wind disperses rejuvenator application. Delay application if rain appears imminent within 8 hours following time of application.

Concrete Pavement Maintenance

Crack sealing is most effective when performed on concrete pavements that exhibit low-severity structural deterioration and when the cracks are full-depth but relatively narrow, with minimal spalling. Crack sealing may be used on cracks of low or medium severity where the crack width is 0.5 inch (13 millimeters) or less. If load transfer restoration (LTR) or partial-depth patching at the crack location is to be applied, seal cracks after these activities have been completed. If the cracks have deteriorated and exhibit a high degree of spalling, consider full-depth patching. Material for sealing cracks should meet ASTM standards for the type of pavement and service for which the sealant is intended. Typical crack sealant shall meet ASTM

D5893, Standard Specification for Cold Applied, Single Component, Chemically Curing

Silicone Joint Sealant for Portland Cement Concrete Pavements. Backer rod shall be installed in the cracks. Backer rod shall meet D5249, Standard Specification for Backer Material for Use with Cold- and Hot-Applied Joint Sealants in Portland-Cement Concrete and Asphalt Joints.

Typical backer rod materials are polychloroprene, polystyrene, polyurethane, and polyethylene closed-cell forms. Do not use paper, rope, or cord. Use a backer rod material with a melting temperature that is at least 25 degrees F (14 degrees C) higher than the sealant application temperature to prevent damage during sealant placement. Spalling can occur when unsealed joints or cracks are filled with incompressible materials that prevent movement of the slab in hot weather and result in breakage of the concrete. Spalls create a rough ride and can accelerate deterioration. Spalling is typically a localized distress and warrants a localized repair in some cases a full-depth repair is needed. All concrete pavement maintenance will conform to

UFC 3-270-01. Failure to field verify the dimensions and quantities will be at the contractor’s risk and shall not relieve the contractor from accomplishing the work required by the contract at no additional cost to the Government.

Additional General Requirements:

• All work will meet the International Building Code, Uniform Plumbing Code, National Electrical Code, NFPA 72, UFC 3-270-01, and any other applicable code requirement.

• All airfield re-striping to conform to UFGS 32 17 23.19

• Maintain work site in a clean and orderly manner so that the safest possible site is provided for workers and AF members.

• In the event of a conflict between the drawings and the Statement of Work

(SOW), the SOW will take precedence.

• Protect existing runway markings, lights, and other fixtures from damage during cleaning and sealant application.

• Infrastructure:

The Contractor shall furnish all necessary infrastructure and incidentals to the installation of the prime mission equipment. The Contractor shall ensure that the infrastructure conforms to Offutt Design Compatibility Guidelines (DCG) for base architectural and civil engineering standards, all applicable base construction standards and complies with applicable federal, state, and local codes and regulations. The Contractor shall be responsible for coordinating an AF Form 103, Base Civil Engineer Work Clearance

Request, prior to performing digging of any type. It shall be the Contractor's responsibility to coordinate the completion of the necessary AF Form 103 and arrange to have existing utilities located as indicated on the completed form, prior to the beginning of digging operations in the individual areas. This coordination is anticipated to take approximately three (3) working days to complete per request and may require coordination with as many as twenty (20) individuals located on or near the base. Digging near existing utilities shall be done by hand, five (5) feet either side of the point along the intended route, in order to prevent disturbing the existing utility. If the existing utility is uncovered in the new excavation, it shall be protected from damage and movement while in the open excavation and during backfill. The contractor shall be responsible for the repairs and associated costs for repairs of any utility damaged by their installation work, whose location was made known to the Contractor.

• Item: Equipment Installation and Integration:
