SECTION 32 01 18.71 Page 3

1.2 EQUIPMENT, TOOLS, AND MACHINES

1.2.1 Grooving Machine

Provide a grooving machine that is power driven, self-propelled, specifically designed and manufactured for pavement grooving, and has a self contained and integrated continuous slurry vacuum system as the primary method for removing waste slurry. Equip the grooving machine with diamond-saw cutting blades capable of making at least 457 mm 18 inches in width of multiple parallel grooves in one pass of the machine. Use cutting blades capable of making the required width and depth of grooves in one pass of the machine. A mixture of new and worn blades or blades of unequal wear or diameter are not permitted in the cutting head. Match the blade type and configuration with the hardness of the existing airfield pavement. Use wheels on the grooving machine that will not scar or spall the pavement. Provide the machine with devices to control depth of groove and alignment within the specified tolerances.

Submit a list of proposed equipment to be used in performance of this work, including descriptive data and safety precautions required for the equipment operation.

1.3 ENVIRONMENTAL REQUIREMENTS

Grooving operations will not be permitted when freezing conditions prevent the immediate removal of debris and/or drainage of water from the grooved area. The Contractor is responsible for discharge and disposal of waste slurry. Waste slurry discharge pits may be constructed along side the pavement to be grooved, as directed by the Contracting Officer. Provide and maintain temporary storm drainage, pollution control, and erosion control features at each discharge pit in accordance with base environmental regulations. Excavate and dispose of hardened waste slurry [off base] [in accordance with the base waste disposal requirements] after it has been dewatered. Regrade and restore to original condition all disposal pit areas.

Pavement s shoul d not be gr ooved unt i l t hey ar e at l east 30 days ol d.

3.1.1 Existing Pavements

Do not groove bumps, depressed areas, bad or faulted joints, and badly cracked and/or spalled areas in the pavement until such areas are adequately repaired or replaced.

3.1.2 New Pavements

Allow new asphalt concrete pavements to cure for a minimum of 30 days before grooving, to allow the material to become stable enough to prevent closing of the grooves under normal use. Permit new portland cement concrete pavements to cure for a minimum of 28 days before grooving.

3.2 WATER SUPPLY

NOTE: I f t r anspor t at i on of t he wat er by sur f ace l ai d pi pe i s per mi t t ed, r out i ng of t he pi pe shoul d be shown. I dent i f y t he avai l abl e sour ce l ocat i on on t he dr awi ngs.

[Provide water for the grooving operation] [The Government will provide water for the grooving operation].

3.3 GROOVING

3.3.1 Procedures

Submit grooving sequence and method of placing guide lines to control grooving operation. Cut grooves in the [asphalt] [portland cement] areas as indicated on the drawings. Begin the grooving at one side of the usable [runway] [taxiway] and continue for the full width of the area.

Take all reasonable precautions to prevent damage to or roughening of the pavement between grooves. Spalling along or tearing or raveling of the groove edges will not be allowed. Cut grooves that are 6 mm, plus 2 mm, minus 0 mm 1/4 inch, plus 1/16 inch, minus 0 inch wide by 6 mm, plus or minus 2 mm 1/4 inch, plus or minus 1/16 inch deep and 38 mm, plus 0 mm, minus 3 mm 1-1/2 inches, plus 0 inches, minus 1/8 inch center to center spacing. Cut grooves that are [_____] meters feet plus or minus 75 mm 3 inches long and normal to the longitudinal axis of the centerline of the

SECTION 32 01 18.71 Page 5

[runway] [taxiway]. The transverse alignment of the grooves must not vary more than 75 mm 3 inches plus or minus on a 23 m 75 foot length of grooving. Do not groove within 150 mm plus or minus 75 mm 6 inches plus or minus 3 inches of the runway centerline. Do not groove within 150 mm 6 inches of transverse joints or working cracks, through compression seals, in-runway lighting fixtures or similar items, the first 3 m 10 feet either side of an arresting barrier cable or the first and last 3 m 10 feet of the runway.

3.3.2 Clean-Up

Continously clean-up debris from the grooving operation. Flush debris produced by the equipment to the edge of the grooved area or pick it up before it dries and hardens. Flush the remaining dust coating to the edge of the area if the resultant accumulation is not detrimental to the vegetation or storm drainage system. Accomplish all flushing operations in a manner to prevent erosion on the shoulders, damage to vegetation, or plugging of storm drainage.

3.3.3 Repair of Damaged Pavement

Repair at the Contractor's expense, [as specified in Section [_____],] any damage, which in the opinion of the Contracting Officer will be detrimental to aircraft operations and/or pavement performance, occurring to the pavement as a result of the grooving operations.

3.4 CONTRACTOR QUALITY CONTROL

3.4.1 Test Section

Groove a test section [_____] m feet long by two lanes wide in an area of the pavement outside of the trafficked area, as approved by the Contracting Officer. Demonstrate the setup and alignment process, the grooving operation, and the waste slurry disposal.

3.4.2 Inspections

At the beginning of each work shift, furnish a full complement of grooving blades with each saw that are capable of cutting grooves of the specified width, depth, and spacing. If during the work, a single grooving blade on a machine becomes incapable of cutting a groove, continue work for the remainder of the work shift. The Contractor is not required to cut the groove omitted because of the failed blade. Should two or more grooving blades on a machine become incapable of cutting grooves, cease operating the machine until it is repaired.
