General Description of Cationic Bitumen Emulsion K1-60
Bitumen K1-60 cationic bitumen emulsion contains a minimum of 57% bitumen. This medium viscosity emulsion is suitable for grouting. The production of K1-60 cationic bitumen emulsion follows KS 02-769: 1990 standard.
Interestingly, Bitumen Emulsion K1-60 is cold-applied and liquid-based, making it ideal for constructing and repairing pavements, driveways, roads, and highways. The prefix ‘K’ indicates a cationic emulsion, while ‘1’ signifies rapid breaking. The number after the hyphen reflects the bitumen content, hence K1-60 denotes rapid break, cationic emulsion with 57% normal bitumen content.
Uses of Cationic Bitumen Emulsion K1-60
Grade K1-60 serves as a tack coat, creating a strong bond between existing surfaces and overlays, like hot-rolled asphalt, macadam, and slurry seals.
Key purposes include:
1. Reducing spillage risks between layers.
2. Minimizing sliding during overlay, improving compaction.
With higher bitumen content, Grade K1-60 supports surface dressing, patching, and retreading applications.
Applications:
- Single surface treatment
- Multiple surface treatment
- Sand seal
For penetration macadam:
- Small voids
K1-60 is suitable for tack coating in night construction or high humidity. It applies effectively at ambient temperatures with aggregates that don’t require complete drying.
Application Conditions of Cationic Emulsion Grade K1-60
Apply Grade K1-60 at ambient temperature with a spray rate of 0.25 to 0.70 liters per square meter (0.05 to 0.15 gallons per square yard).
Ensure dry, frost-free conditions between 5°C and 35°C. Before application, roll drums to mix contents thoroughly. Apply using a broom, squeegee, or spray for uniform distribution. Spray equipment should meet BS3136 standards.
Preparation:
Surfaces should be dry, clean, and free from dust, oil, and debris. In hot conditions, lightly dampen surfaces to slow water loss and improve adhesion, avoiding standing water during application.
Packing of Cationic Emulsion K1-60
Available in:
- IBC Tank, Flexi Tank (bulk)
- Reconditioned steel drums (200 liters)
- New steel drums (200 liters)
