RC 70

RC-70 is a type of cutback bitumen, produced using a petroleum solvent, usually naphtha or gasoline. This bitumen type, due to its higher fluidity, can be used at ambient temperatures without requiring much heating. The term RC stands for Rapid Curing, indicating its fast-drying properties due to the high evaporation rate of its solvent. The number 70 represents the viscosity of the bitumen at 60°C.

Features of RC-70 Bitumen

1. Fast Drying: RC-70 bitumen dries quickly due to the use of volatile solvents, making surfaces ready for use in a short time.
2. High Adhesion Strength: Its excellent adhesion makes it ideal for surface stabilization and bonding.
3. Ease of Use: Thanks to its high fluidity, it can be applied at ambient temperatures without direct heating.
4. Resistance to Temperature Variations: RC-70 bitumen withstands temperature changes, making it suitable for diverse climatic conditions.

Applications of RC-70 Bitumen
Due to its unique properties, RC-70 bitumen is widely used in road construction and building projects. Its primary applications include:

1. Cold Asphalt: Used in producing cold asphalt due to its high fluidity and fast-drying time.
2. Tack Coat: Applied to create adhesion between asphalt layers.
3. Soil Stabilization: Used to stabilize soil surfaces and prevent water penetration.
4. Road Maintenance: Ideal for repairing and maintaining roads to prevent cracks and further damage.

Advantages of RC-70 Bitumen over Other Types

• Faster Execution: Projects can be completed more quickly due to its rapid drying.
• Lower Energy Costs: It does not require heating and can be used at ambient temperatures.
• Weather Resistance: Offers good resistance to moisture and temperature fluctuations.

Safety Tips for Using RC-70 Bitumen

• The solvent in RC-70 is flammable; hence, it should be stored in well-ventilated areas away from open flames.
• Use of safety equipment like gloves and masks is recommended when handling this product.
• Proper packaging and prevention of solvent leakage are essential during transportation.

RC-70 bitumen is one of the best options for road construction and maintenance projects, especially in areas where fast execution and lower costs are priorities. Its physical and chemical properties give it a significant edge in the construction industry, making it suitable for various projects.
