43 4. Improved Safety: By addressing small surface cracks and reducing loose gravel or “raveling,” this treatment helps maintain a smoother, safer surface for both vehicles and pedestrians. Spray Applied Surface Treatments are produced in centralized facilities to ensure consistent quality. For optimal results, it’s advisable to consult the manufacturer for guidance on curing times, coverage rates and surface preparation, as these may vary by product. Seal Coat ($$) An asphalt seal coat is a protective layer applied to asphalt pavement to shield it from damage caused by weather, UV rays, chemicals and daily wear and tear. This treatment is typically made from a blend of asphalt emulsion, mineral fillers, water, and performance-enhancing additives. Acting as a durable barrier, it not only extends the lifespan of the pavement but also enhances its appearance. Seal coats are suitable for various surfaces, including roads, parking lots, walking trails and driveways. HOW AN ASPHALT SEAL COAT IS APPLIED 1. Surface Preparation: • The pavement is thoroughly cleaned to remove debris, dirt and oils. • Cracks and potholes are filled and repaired to ensure a smooth application surface. 2. Application: • The seal coat is applied using spray equipment, squeegees or brushes. • It is evenly applied in thin layers, often requiring one or two coats based on the pavement’s condition. 3. Curing: • Seal coats typically require 24-48 hours to cure before the pavement is reopened to traffic. BENEFITS OF AN ASPHALT SEAL COAT 1. Protection Against the Elements: • Shields the pavement from UV rays, water and oxidation, which can degrade asphalt over time. 2. Prevention of Cracks and Potholes: • Exposure to sunlight and air causes asphalt to oxidize over time, making it brittle and prone to cracking. Seal coat blocks harmful UV rays and slows down oxidation, preserving the asphalt’s flexibility and preventing it from becoming fragile. 3. Enhanced Durability: • Adds a protective layer that minimizes wear and tear from traffic and heavy vehicles. 4. Improved Appearance: • Restores the pavement’s rich black color, giving it a newer and more attractive look.
