Asphalt sealant is a high quality hot applied crack sealant, composition of asphalt cement, virgin synthetic polymer, premium rubber, and other modifiers.It’s solid at normal temperature, and will change into gel of super stretch and adhesion after being melted by heating, which can effectively seal cracks and joints in the pavement and remain sealed effects in long-term.
Why Your Pavement Needs It
Stop Water Damage: Water is asphalt’s worst enemy—it seeps into cracks, freezes, expands, and weakens the pavement structure (causing potholes). Sealant creates a watertight barrier, blocking moisture from penetrating.
Prevent Oxidation: Sunlight and oxygen dry out asphalt, making it brittle and prone to cracking. Sealant adds flexibility, letting the pavement “bend” without breaking under traffic or temperature shifts.
Fill Cracks & Joints: It seals small to medium cracks to stop them from growing into larger damage.
Restore Appearance: A fresh sealant coating revives dull, faded asphalt, giving it a sleek, dark finish that boosts curb appeal.
Application Scenario
Highways & Freeways: Withstands heavy truck traffic and extreme temperature swings (-30°C to +90°C).
City Streets & Parking Lots: Protects against daily wear, UV rays, and freeze-thaw cycles.
Airport Runways: Meets strict safety standards for runway durability and smoothness.
Driveways & Sidewalks: Extends the life of residential and commercial pavement.
Asphalt sealant isn’t just a “quick fix”—it’s a long-term strategy to save money, enhance safety, and preserve your infrastructure.
