Section (1616-VB-WPGM)BR25

Backer Rod. The backer rod shall conform to ASTM D 5249, type 3.

Construction Requirements. The Contractor shall furnish the Engineer with the manufacturer’s product information and installation procedures at least two weeks prior to installation When placing the silicone against concrete, the concrete surface shall be dry. For newly placed concrete, the concrete shall be fully cured and allowed to dry out a minimum of seven additional days prior to placement of the silicone. Cold, wet, inclement weather will require an extended drying time.

Surface Preparation:

Sandblasting. Both faces of the joint shall be sandblasted. A separate pass for each face for the full length of the joint and to the design depth of the center of the backer rod will be required. The nozzle shall be held at an angle of 30-90° to the joint face, at a distance of 1–2 in.

For PCC and polymer concrete surfaces, sandblasting will be considered acceptable when both joint faces have a roughened surface with clean, exposed aggregate. The surface shall be free of foreign matter or plastic residue. For steel surfaces, sandblasting will be considered acceptable when the steel surfaces have been cleaned to an SSPC-SP10 degree of cleanliness.

After sandblasting is completed, the joint shall be cleaned of debris using compressed air with a minimum pressure of 90 psi. The air compressor shall be equipped with traps to prevent the inclusion of water and/or oil in the air line.

Priming. Priming shall be according to the manufacturer’s instructions. This operation will immediately follow sandblasting and cleaning and will only be permitted to proceed when the air and substrate temperatures are at least 41 °F and rising. Sandblasting, priming, and sealing shall be performed on the same day. Surfaces to be primed shall be primed using a brush applied primer. For steel surfaces, when specified per the manufacturer’s instructions, the primer shall be allowed to cure before proceeding. The minimum cure time shall be extended according to the manufacturer’s recommendations when the substrate temperature is below 60 °F.

The primer shall be supplied in original containers and shall have a “use-by” date clearly marked on them. Only primer freshly poured from the original container into clean pails will be permitted.

The primer shall be used immediately. All primer left in the pail after priming shall be disposed and shall not be reused.

Joint Installation:

Backer Rod Placement. The backer rod shall be installed to a uniform depth as specified on the plans and as recommended by the manufacturer. All splices in the backer rod shall be taped to prevent material loss during sealing. The backer rod shall be installed to within 1/8 in. tolerance prior to sealing.

Section (1616-VB-WPGM)BR25

Sealant Placement. The sealant shall be 1/2 in. thick within ±1/8 in. tolerance as measured in the center of the joint at the thinnest point. The sealant thickness shall be measured during installation every ±2 ft. Adjustments to correct sealant thickness to within tolerance shall be made immediately before the sealant begins to set up. Sealant placement will only be permitted when the air and substrate temperatures are above 41 °F and 5 °F above the dew point. The joint shall be kept clean and dry during sealing. If the joint becomes wet and/or dirty during sealing, the operation shall stop until the joint has been restored to a clean and dry state.

Sealing shall be performed using a pneumatic gun approved by the sealant manufacturer. Prior to sealing, the gun shall be inspected to ensure that it is in proper working order and is being operated at the recommended air pressure. The gun shall demonstrate proper mixing action before sealant is placed in the joint. All unmixed sealant found in the joint shall be removed and replaced.

After the Engineer has determined that the pneumatic gun is functioning properly, the joint shall be sealed to the thickness and depth as shown on the plans.
