II. DESCRIPTION OF WORK

1. Scope of Services

Phase 1: Site Preparation & Cleaning

• Sweeping & Debris Removal: Thoroughly clean the pavement surface using power sweepers, rotary brooms, and high-pressure wire brooms to remove all loose dirt, gravel, vegetation, oil, and debris.

• Oil/Grease Stain Treatment: Apply an approved chemical oil/grease primer or degreaser to all saturated petroleum stains to prevent bleed-through and ensure proper adhesion of subsequent sealers.

Phase 2: Asphalt Patching & Repair (Failed/Alligator Areas)

• Saw-Cutting: Perimeter-cut all severely alligator-cracked, rutted, or structurally failed pavement areas using a diamond blade saw to a depth of 3–4 inches. Cuts must be clean, straight, and vertical, extending 6 inches past the deteriorated zone into sound pavement.

• Excavation & Base Repair: Excavate removed pavement and inspect the underlying base rock. Compact the base material; if subgrade failure is present, backfill with crushed aggregate base rock and compact to 95% Relative Compaction.

• Tack Coat: Apply a uniform spray coat of asphalt emulsion (SS-1h or equivalent) to all vertical saw-cut edges and exposed base rock.

• Asphalt Placement: Fill excavated areas with Hot Mix Asphalt (HMA), laid in lifts not exceeding 2 inches, and compact using a vibratory roller to match the surrounding grade.

SPECIFICATIONS S-2 CSD-27-003-O

Phase 3: Crack Filling & Sealing

• Crack Cleaning: Clean all cracks wider than 1/8 inch (3 mm) using high-pressure compressed air and heat lance to burn away vegetation and moisture.

• Hot-Applied Sealant Placement: Inject a hot-applied, rubberized crack sealant meeting ASTM D6690 specifications directly into cleaned cracks.

Overband cracks using a rubber squeegee flush with the adjacent pavement surface (maximum 2-inch wide band).

Phase 4: Leveling Low Spots (Depressions)

• Tack Coat Application: Spray tack coat liberally over depressed low spots holding water.

• Leveling/Skin Patching: Apply a fine-aggregate hot mix asphalt or high-performance cold/warm polymer-modified asphalt skin patch to bring low areas flush with surrounding grades, eliminating standing water.

Phase 5: Surface Sealcoating / Top Coating

• Materials: In the specified existing paved area, completely apply an asphalt-emulsion-based sealcoat (or refined coal-tar/polymer alternative) mixed with 3 to 5 lbs of silica sand per gallon and approved latex fortifying polymers for improved skid resistance and durability.

• Application Method: Apply two (2) coats via squeegee or high-pressure spray application.

o First Coat: Uniform application to penetrate and seal surface pores.

o Second Coat: Applied perpendicular to the first coat after the first coat has thoroughly dried (minimum 2–4 hours cure time between coats).

2. Quality Control & Performance Standards

• Water Test: Upon completion, the surface shall be flushed with water.

No standing water deeper than 1/8 inch shall remain after 30 minutes under sunny conditions.
