C. WORK EXECUTION REQUIREMENTS

Parking lot

· Clean and seal all cracks and joints greater than or equal to 1/8 inch in the asphalt surfaces by applying hot mix asphalt to provide a waterproof bond, in accordance with the crack sealant manufacturer’s recommendations and the Washington State Department of Transportation's “Standard Specifications for Road, Bridge, and Municipal Construction,” Section 5-03.

· The crack should be slightly overfilled and leveled with a 3-inch sealing disk or a V-shaped squeegee.

· Crack sealing should only occur when environmental conditions are favorable and in accordance with the manufacturer’s recommendations for the crack sealant. Final crack cleaning will occur on the same day as the sealing operation.

· The existing asphalt surface shall be cleaned in accordance with the Washington State Department of Transportation “Standard Specifications for Road, Bridge, and Municipal Construction” Chapter 5-03.3(1), and all debris resulting from the cleaning must be removed from the site by the Contractor. The contractor will furnish all necessary equipment, supervision, labor, materials, tools, traffic control, and incidentals for the job.

Strip Painting/ADA marking

· The parking lot and curbs shall be painted according to the manufacturer’s recommendations. The Contractor shall verify measurements and evaluate actual site conditions.

· The international symbol of accessibility shall comply with the ABA Standards for Accessible Design.

· The pavement markings shall include the delineation of parking stalls, crosswalks, access routes, no parking zones, and handicapped parking designations.

· Paint shall be applied in dry weather and only when the pavement and atmospheric temperatures are above 45°F and are anticipated to remain above 45°F for eight hours after completion.

· Application will not be permitted when precipitation is anticipated or when temperature and humidity conditions are such that the paint cannot dry thoroughly.

· The paint will be applied with mechanical equipment to produce uniform, straight edges.

Crack Sealant (Fog seal)

· Follow the manufacturer’s recommendations for crack cleaning.

· Use prepackaged, hot-pour rubberized asphalt crack sealer specifically formulated for slow-moving vehicle traffic and foot traffic, such as parking lots.
