however, the Contractor will be responsible for providing and maintaining backflow prevention on the connection. Inspection and approval by the Base Fire Department is required prior to any use of the Base water systems.

3. DESCRIPTION OF WORK

3.1. The Contractor shall repair 202,400 linear feet of joint sealant in concrete airfield pavements by replacement at the locations shown in the Project Drawings. The joint sealant being installed on Apron pavements is required to be jet fuel resistant joint sealant. Approximately 111,320 linear feet of the joint sealant being replaced are on the apron pavements and approximately 91,080 linear feet of the joint sealant being replaced are on taxiway pavements. The Contractor shall mechanically remove the existing failed joint sealant, clean and reface pavement joints, and replace with new backer rod and sealant. The Contractor shall limit the stages of joint preparation, including sandblasting, air pressure cleaning and placing of the back-up material to only that lineal footage that can be sealed during the same day. The Contractor is responsible to dispose of all waste materials. Where spalling along a joint is so bad that replacing the joint sealant causes pavement damage, which will cause foreign object debris (FOD) a spall repair shall be performed at that location to mitigate the risk of FOD.

3.2. Completely remove existing joint sealants (full depth), clean and reface concrete pavement joints, and install new sealant in the airfield pavements at the locations shown in Project Drawings in accordance with the UFGS 32 01 19.61 Sealing of Joints in Rigid Pavements Specification and UFM 3-270-01. The total length of joints to be re-sealed is 202,400 linear feet.

3.3. The Contractor shall be prepared to perform concrete spall repairs, in accordance with the UFGS 32 01 29.61 Partial Depth Patching of Rigid Paving Specification and UFM 3-270-01, at locations where the concrete adjacent to the joints is damaged during the removal of the existing sealant. The scope of spall repair includes: saw-cutting the boundaries of the spalled area to create a clean, vertical edge, removal of all unsound concrete from within the repair area, cleaning the repair area and applying a bonding agent, if required by the repair material manufacturer, placing, finishing, and curing a rapid-setting concrete patching material that meets the strength and durability requirements for airfield pavements.

3.4. The Contractor shall replace pavement markings if damaged during construction or if removed for pavement spalling repairs.

3.5. The work will be performed in six (6) different phases. Refer to the drawings for the

Phasing locations.

3.6. At all times the Contractor shall leave a travel lane down Taxiway A open for emergency vehicles.

3.7. TRIAL JOINT SEALANT INSTALLATION

3.7.1. Prior to cleaning and sealing the joints for the entire project, prepare a test section at least 200 ft long using the specified materials and approved equipment, so as to demonstrate the proposed joint preparation and sealing of the types of joints in the project. Following the completion of the test section and before any other joint is sealed, inspect the test section to determine that the materials and installation meet the requirements specified. Inspect joint seal test section. (Provide written notice of deficiencies and required corrections or adjustments in the joint seal installation procedures.) Correct deficiencies and obtain approval of test section prior to installing joint seals. If it is determined that the materials or installation do not meet the requirements, remove the materials, and reclean and reseal the joints at no cost to the Government. Permit the test section meeting the requirements to be incorporated into the permanent work and paid for at the Contract unit price per linear foot for sealing items scheduled. Prepare and seal other joints in the manner approved for sealing the test section. Notify the Contracting Officer (CO) upon completion of the test section.

3.8. PREPARATION OF JOINTS

3.8.1. Unless otherwise indicated, remove existing material, saw, clean and reseal joints. Do not proceed with final cleaning operations by more than one working day in advance of sealant. Clean joints by removing existing joint sealing compound, bond-breakers, dirt, laitance, curing compound, filler, and protrusions of hardened concrete from the sides and upper edges of the joint space to be sealed and other foreign material with the equipment. Do not permit cleaning procedures that damage joints or previously repaired patches by chipping or spalling. Remove existing joint sealant to the required depth.

Precise shape and size of existing joints vary, and conditions of joint walls and edges vary and include but are not limited to rounding, square edges, sloping, chips, voids, depressions, and projections.

3.9. EXISTING SEALANT REMOVAL

3.9.1. Cut loose the in-place sealant from both joint faces and to the required depth, using the method and equipment as specified in Section 3.17. Provide a depth sufficient to accommodate blocking media and bond breakers that are required to maintain the depth of new sealant to be installed. For expansion joints, remove existing joint sealant to a depth of not less than 1 in. When existing preformed expansion-joint material is more than 1 in below the surface of the pavement, remove existing sealant to the top of the preformed joint filler. Prior to further cleaning operations, remove loose old sealant remaining in the joint opening by blowing with compressed air. Permit use of hand tools to remove sealant from random cracks. Do not permit chipping, spalling, or other damage to the concrete. Clean pavement surface with vacuum sweeper. Protect previously cleaned joints from being contaminated by subsequent cleaning operations.

3.10. SAWING

3.10.1. Joints often need to be refaced or widened to provide vertical faces and remove damaged concrete. Care should be used when refacing or widening joints so that the joint's width does not exceed 1 in. If the joint width exceeds 1 in, rebuilding of the joint should be considered. Joint walls should be vertical. The edges should not be rounded or beveled unless required by design.

3.10.2. Joints shall be refaced by sawing to widen the joint space or change the shape factor as required or straighten the vertical walls inside the joints and remove old sealant.

3.11. REFACING OF JOINTS

3.11.1. Accomplish refacing of joints using a concrete saw as specified in Section 3.17 to remove residual old sealant and a minimum of concrete from the joint face to provide exposure of newly cleaned concrete, and, if required, to enlarge the joint opening to the width and depth shown on the drawings. Provide exposure of newly clean concrete through removal. Remove burrs and irregularities from sides of joint faces. Stiffen the blade with a sufficient number of dummy (used) blades or washers. Clean, immediately following the sawing operation, the joint opening using a water jet to remove saw cuttings and debris and adjacent concrete surface. Protect adjacent previously cleaned joint spaces from receiving water and debris during the cleaning operation.

3.11.2. Joint Widening (Except Expansion Joints): Saw joints having grooves less than 3/8 in. wide and less than 1 in. deep to a minimum width of 3/8 in and to the minimum depth, of 1 in.

3.12. FINAL CLEANING OF JOINTS

3.12.1. Sandblasting: Following removal of existing sealant, and sawing, and immediately before resealing, clean newly exposed concrete joint faces and pavement surface extending to a minimum of 1/2 in up to 2 in from each joint edge by sandblasting until concrete surfaces in the joint space are free of sealants, dust, dirt, water and other foreign materials that prevent bonding of new sealants to the concrete. Use sand particles of the proper size and quality for the work. Perform sandblasting with specified nozzles, air compressor, and other appurtenant equipment. Position nozzles to clean the joint faces. Make at least two passes; one for each joint face. Make as many passes as required for proper cleaning. Immediately prior to sealing the joint, blow out the joint spaces with compressed air until completely free of sand, water, and dust.

Install joint sealants to dry joints. Replace expansion joint filler material damaged in performing the work with new materials of the same type and dimensions as the existing material, or with appropriate blocking media.

3.12.2. Sandblasting media shall be vacuumed and collected for proper disposal.

3.13. BOND BREAKER

3.13.1. At the time the joints receive the final cleaning and are dry, install bond breaker material as indicated with a steel wheel or other approved device.

3.13.2. Backer Rod (except for expansion joints): When the joint opening is of a greater depth than indicated for the sealant depth, plug or seal off the lower portion of the joint opening using a blocking media/back-up material to prevent the entrance of the sealant below the specified depth. Take care to ensure that the blocking media/backup material is placed at the specified depth and is not stretched or twisted during installation.

3.13.3. Bond Breaking Tape: Where inserts or filler materials contain bitumen, or the depth of the joint opening does not allow for the use of a backup material, insert a bond breaker separating tape to prevent incompatibility with the filler materials and three-sided adhesion of the sealant. Bond the tape to the bottom of the joint opening to prevent it from floating up into the new sealant.

3.14. PREPARATION OF SEALANT

3.14.1. Prior to installing any joint sealant, the Contractor shall sweep pavement surface to remove excess joint material, dirt, water, sand, and other debris by vacuum sweepers or hand brooms. Remove the debris immediately.

3.14.2. Hot-Poured Sealants: Heat hot-poured sealing materials in accordance with ASTM D6690 and with safe heating temperature ranges recommended by the manufacturer. Withdraw and waste sealant that has been overheated or subjected to heating for over 3 hours or that remain in the applicator at the end of the day's operation. Heat sealant in the specified equipment.

3.14.3. Single-Component, Cold-Applied Sealants: Inspect the ASTM D5893/D5893M sealant and containers prior to use. Reject materials that contain water, hard caking of any separated constituents, non-reversible jell, or materials that are otherwise unsatisfactory. Do not reject sealants that exhibit settlement of constituents in a soft mass that can be readily and uniformly remixed in the field with simple tools.

3.15. INSTALLATION OF SEALANT

3.15.1. After approval of the test section, seal joints immediately following final cleaning and placing of bond breakers. Commence sealing joints when walls are dust free and dry, and when weather conditions meet sealant manufacturer's instructions. If the above conditions cannot be met, or when rain interrupts sealing operations, reclean and permit the joints to dry prior to installing the sealant.

3.15.2. Do not install joint sealant until joints to be sealed have been inspected and approved. Install bond breaker just prior to pouring sealant. Fill the joints with sealant from bottom up until joints are uniformly filled solid from bottom to top using the specified equipment for the type of sealant required. Fill joints to 1/8-in below top of pavement, and without formation of voids or entrapped air. Do not permit gravity methods or pouring pots to be used to install the sealant material. Except as otherwise permitted, tool the sealant immediately after application to provide firm contact with the joint walls and to form the indicated sealant profile below the pavement surface. Remove excess sealant that has been inadvertently spilled on the pavement surface. Do not permit traffic over newly sealed pavement until authorized. When a primer is recommended by the manufacturer, apply it evenly to the joint faces in accordance with the manufacturer's recommendations. Check sealed joints frequently to ensure that newly installed sealant is cured to a tack-free condition within the specified time. Protect new sealant from rain during curing period.

3.15.3. Joints should be slightly underfilled to preclude extrusion of the material above the surface of the pavement at summertime temperatures. For airfield pavements, the sealant should be recessed 1/8-in below the pavement surface.

3.16. PRODUCTS

3.16.1. The Sealant products used on this project shall comply with the requirements set forth in UFGS Specification 32 01 19.61.

3.16.2. Use self-leveling, non-acid curing silicone sealant meeting ASTM C920 or ASTM C1193 requirements. For joints being installed on Apron pavements the Contractor shall install jet fuel resistant joint sealants.

3.16.3. Provide backup (joint filler) material that is a compressible, nonshrinking, nonstaining, nonabsorbing, nonreactive material with the sealant. Use backup material compliant with ASTM D5249. Use material with a melting point at least 5 degrees F greater than the pouring temperature of the sealant being used when tested in accordance with ASTM D789. Use material with a water absorption of not more than 5 percent of the sample weight when tested in accordance with ASTM C1016. Use backup (joint filler) material that is 25 plus or minus 5 percent larger in diameter than the nominal width of the crack. Use blocking media consistent with the sealant manufacturer's installation instructions.

3.16.4. Provide a bond breaking tape or separating material that is a flexible, nonshrinkable, nonabsorbing, nonstaining, and nonreacting adhesive-backed tape.
