Frequently Asked Questions
DURAPAVE EMULSIS CSS1 (H) is a slow-setting bitumen emulsion specially designed for road construction and maintenance applications. It is widely used for tack coat applications, fog seals, crack sealing, surface dressing, and maintenance treatments where strong bonding and extended workability are required.
DURAPAVE EMULSIS CSS1 (H) offers several benefits, including excellent adhesion to aggregates and existing pavement surfaces, enhanced pavement durability, and easy application. Its slow-setting properties allow better penetration and coating, making it suitable for preventive maintenance and long-lasting road performance.
- DURAPAVE EMULSIS CSS1 (H) improves adhesion by creating a strong bonding layer between existing and new asphalt surfaces. It reduces the risk of delamination, improves structural integrity, and increases the lifespan of the pavement.
- Yes, DURAPAVE EMULSIS CSS1 (H) is suitable for fog-seal and crack-seal applications. Its slow-setting formulation allows deep penetration into minor surface cracks and aged pavements, helping to restore flexibility. Fog-seal treatments using this emulsion also improve surface appearance and extend pavement service life.
