(b) Deck cleaning procedure. Remove the existing asphalt concrete wearing surface and aggregate base prior to placing the sealer. Take care not to damage the stone curbing.

Thoroughly clean the entire surface of the existing concrete deck by blast cleaning (sand or shot blast). Ensure cleaning debris does not enter creeks or waterways. Care shall be taken while cleaning that all dirt is removed. Do not damage the concrete surfaces. Remove all traces of laitance, grease, dirt, dust, oil, asphalt, paint, or other foreign materials which may prevent penetration.

Prepare the deck surface so that it is smooth and free of voids, sharp projections, form release agents, concrete curing agents, and other contaminants.

Install erosion control devices/sandbags as necessary to ensure that no materials are directly discharged into streams.

Dispose of all removed materials according to Subsection 203.05.

(c) Surface preparation. The surface shall be dry and be vacuum cleaned to remove loose particles immediately before the sealer is applied. If the concrete is subjected to rain or moisture, the surface shall be allowed to air dry for a minimum of 24 hours before the sealer is applied. In the early morning before noon the CO may direct a waiting period for drying by the sun on the surfaces to be sealed.

If the surfaces are not sealed within 7 calendar days after the blast cleaning, the CO, due to debris, may direct a pressure wash, air dry for a minimum of 24 hours and then vacuum clean of the total or partial surface to be sealed at the Contractor’s expense.

All surface preparation work shall be completed and approved by the CO, before sealer application can commence.

(d) Weather limitations. Sealer materials shall not be applied during wet weather conditions, or if adverse weather conditions are anticipated within 4 hours of the completion of sealer application, or if rain has fallen within a period of 24 hours prior to application.

Ambient and surface temperatures shall be between 40º and 90º F per the manufacturer’s recommendations at the time of application and until the sealed concrete is dry to the touch.

(e) Sealer application. Plug all deck drains and scuppers to prevent sealer from flowing off the bridge. Do not use sand dikes to divert sealer from deck drains and scuppers. Collect and dispose all excess sealer material properly.

The sealer shall be used as supplied by the manufacturer without the use of any thinning alterations, or additives unless specifically required in the manufacturer's instructions.

Thorough mixing of the sealer before and during its use shall be accomplished as recommended by the manufacturer. The CO will view any mixing of all materials. The equipment for all sealing operations will be clean of foreign materials and in good working order for the application rate.

F-23c

Project: MT PRA GLAC 10(40), Going-to-the-Sun Road Rehabilitation Rising Sun to St. Mary, Phase 13

Apply sealer on the top surface of the bridge decks to the limits shown on the plans.

Care shall be taken to ensure that the entire surface of the concrete is covered and all pores filled.

Mix and apply the resin to the deck at a rate recommended by the manufacturer; but not less than 2.5 to 3.5 square meters per liter (11.3 to 15.9 square yards per gallon). Sweep excess resin to untreated areas not less than 10 minutes or more than 20 minutes after the initial application in order to avoid puddle formation. Keep all cracks which are visible to the eye constantly filled for 30 minutes after initial application by using brooms, brushes, or squeegees to refill them.

Hand broadcast dry (less than 0.5 percent moisture) silica sand on the treated area to obtain a uniform coverage of 0.5 kg per square meter (0.9 lb per square yard). Apply the sand before the resin gels. Sand shall be graded such that 100 percent passes a 2.00 millimeter (no. 10) sieve and not less than 98 percent is retained on a 1.00 millimeter (no. 18) sieve.

Do not allow any vehicle or pedestrian traffic on the deck surface until HMWM has fully cured. After HMWM has attained full cure, vacuum or sweep excess sand from deck and curb surfaces. No artificial means to accelerate the drying of the sealer shall be allowed.

Acceptance
