BITUMINOUS CRACK AND JOINT SEALING SECTION 404

137 SECTION 404 — BITUMINOUS CRACK AND JOINT SEALING

404.1Description.

This work consists of sealing existing transverse joints, longitudinal joints, and pavement cracks in existing pavement, existing patches, or around new patch perimeters.

404.2Materials.

A.Crack Sealant Section 1042.1.A

B.Joint Sealant Section 1042.1.B

404.3Construction.

404.3.1 Sealant Equipment. Use sealing equipment specifically recommended by the sealant manufacturer. 404.3.2 Refacing of Pavement. Reface existing pavement using a router to expose sound pavement or cut the joint with a router to the width and depth necessary to provide the joint reservoirs shown in the contract. 404.3.3 Cleaning Before Resealing.

A.Following routing or refacing operations on newly constructed or existing joints, clean the

pavement faces and openings with hot compressed air that is dry and oil free. Use compressed air equipment that delivers a continuous pressure of at least 100 pounds per square inch, measured at the source, to remove cuttings or debris remaining on the pavement faces or in the pavement openi ngs.

B.Equip air compressors with traps capable of removing moisture and oil from the compressed air.

Stop work when there is oil or moisture in the compressed air. Make necessary adjustments to the equipment until the air stream is free of contaminants before resuming work.

C.The Department will not allow placement of sealant if dust, moisture, or other contaminants are

present on the pavement surface.

D.Protect the public from hazard or damage during the cleaning operations by shielding the work

with rigidly supported plywood sheeting or other suitable material and methods subject to the engineer’s approval.

E.Take care not to damage the subbase, curbs, shoulders, load transfer devices, or pavement. If

damage occurs, submit repair procedure for approval and perform repairs to the satisfaction of the engineer. 404.3.4 Limits of Crack and Joint Preparation. Limit the final stages of joint preparation, including air pressure cleaning of joints, and placement of separating or backup material, to the length of joint that will be resealed during a day's production. 404.3.5 Installation of Hot -Poured Sealant.

A.Follow the manufacturer's recommendations for heating and applying the sealant. Provide a copy

of the manufacturer's recommendations to the engineer. BITUMINOUS CRACK AND JOINT SEALING SECTION 404

138 B. Discard and dispose of the first gallon of material to flow out of the applicator wand at the beginning of the day.

C.Place sealant at a uniform, specified depth and thickness. Seal the cracks and joints uniformly so

that upon completion of the work, the surface of the sealant material is 1/16 to 3/16 -inch below the adjacent pavement surface. Remove excess material on the surface of the pavement. Do not allow traffic on the pavement in the area of the cracks and joints during the curing period.

D.Submit repair procedure for failed joints to the engineer for approval.

404.4Method of Measurement.

A.The Department will measure the linear footage along the crack or joint from end to end.

B.The Department will not measure sealed overcuts and will consider these areas as incidental to

the saw cutting item.

404.5Basis of Payment.

A.The Department will pay for the accepted quantity of crack and joint sealing at the contract unit

price per linear foot. Payment constitutes full compensation for:

1.Providing and placing hot -poured joint sealer;

2.joint sawing and refacing;

3.sandblast cleaning; and

4.air-blast cleaning.
