Petra Oil’s CRS-2 is a high-performance cationic rapid setting bitumen emulsion engineered for surface treatments using coarse aggregates. Designed for chip sealing operations on high-traffic roads, CRS-2 offers superior aggregate retention, rapid curing, and long-lasting surface protection under challenging conditions.

This emulsion is ideal for highway networks, arterial roads, and other infrastructure requiring quick construction turnaround and minimal traffic disruption. With its higher viscosity and bitumen content, CRS-2 forms a tough, cohesive film that resists wear, stripping, and moisture infiltration. It cures rapidly after application, enabling fast reopening to traffic and reducing project delays.

CRS-2 is manufactured using premium base asphalt and advanced emulsifiers to meet the rigorous demands of field conditions. Its cationic nature ensures strong bonding with negatively charged aggregates, resulting in improved cohesion and performance. Produced in full compliance with AASHTO M208 standards, this grade is trusted for its consistency and reliability in road maintenance and surface dressing programs.

Key Specifications:

• Emulsion Type: CRS-2 (Cationic Rapid Setting)
• Bitumen Content: Typically, 65–69%
• Viscosity: High
• Break Time: Rapid
• Standard Compliance: AASHTO M208
• Application: Spray using distributor trucks

Main Applications:

• Chip Seals on Highways: Used for coarse aggregate chip seals on busy roadways where durability and quick traffic return are critical.
• Surface Dressing: Ideal for preventative treatments on urban and rural roads to extend pavement life and improve skid resistance.
• Stress-Absorbing Layers: Applied as a binder in SAMIs to minimize cracking caused by reflective stress in pavement overlays.
• Municipal Maintenance: Effective for preserving local road networks exposed to seasonal wear and light-to-moderate traffic.

Key Benefits:

• Strong Aggregate Retention: Keeps coarse aggregate firmly in place under dynamic traffic loading and environmental stress.
• Rapid Return to Service: Breaks and cures quickly, allowing for immediate reopening to traffic and reduced downtime.
• Long-Term Surface Protection: Forms a resilient, water-resistant layer that shields pavement from aging and oxidation.
• Superior Durability: Performs well in varied climates, offering extended lifespan and reduced need for early maintenance.
