The Role of Road Sealant in Asphalt Pavement Marking Restoration
Road sealant is a protective coating applied to asphalt surfaces to restore and preserve line markings, ensuring visibility and safety. Composed of durable materials like coal tar or asphalt-based emulsions, it forms a flexible barrier that shields markings from traffic wear, UV rays, water infiltration, and chemical spills (e.g., oil, gasoline)
Its application involves:
Surface Preparation: Cleaning and repairing cracks or potholes to ensure adhesion
Sealant Application: Applied via spray or squeegee, filling minor cracks and embedding markings for longevity
Curing: Dries within 12-36 hours, forming a resilient layer that extends the life of pavement markings by 2-5 years
Road sealant enhances reflectivity and durability, making it essential for maintaining clear traffic guidance on roads, parking lots, and runways. Regular reapplication every 2-3 years maximizes protection against weathering and traffic stress
