Bitumen Emulsion CRS-1
OVERVIEW OF CATIONIC BITUMEN EMULSION CRS-1
Bitumen Emulsion CRS-1 is a high-quality cationic asphalt emulsion designed for rapid-setting applications. It quickly reacts with aggregate to transition from an emulsion to asphalt. Asphalt emulsions are classified based on the electric charge surrounding the asphalt particles and their ability to separate from water (known as “breaking”). CRS-1 is a cationic emulsion that destabilizes rapidly when in contact with aggregate. It contains 60% bitumen and adheres to the ASTM D 2397M-13 standard. Asphalt Emulsion CRS-1 is primarily used as a tack coat, either as is or diluted with water. It can also be used for fog sealing when diluted with water. The emulsion does not contain clay or similar substances as emulsifying or stabilizing agents. It consists of specially refined asphalt dispersed in water, along with an emulsifying agent. The emulsion remains homogeneous and should not exhibit asphalt separation after thorough mixing for up to 30 days following delivery.
APPLICATION OF BITUMEN EMULSION CRS-1
RAHA OIL offers Bitumen Emulsion CRS-1, a specially formulated water-based emulsion that exhibits low viscosity and fast setting characteristics. This product is particularly well-suited for spray applications, including tack coat spraying. However, one of the primary uses of CRS emulsion is in surface treatment projects such as chip seals, sand seals, and fog seals with cement curing.
With a bitumen content of 60% and a chocolate brown color, RAHA OIL‘s CRS-1 emulsion is a free-flowing liquid at ambient temperature. It cures rapidly and forms robust asphalt films, making it ideal for various spray applications such as spray patching, sand seals, chip seals, and double surface treatments.
KEY BENEFITS AND APPLICATIONS OF CRS-1 EMULSION INCLUDE:
- Ability to apply thicker films for enhanced durability
- Improved coating on aggregates due to the viscosity of CRS-1
- Quick restoration of traffic after application
- Excellent performance in hot temperatures
- Minimized runoff
- Effective sealing of narrow cracks against moisture penetration
- Prevention of slippage between layers
The main application of CRS asphalt emulsion is surface treatment, which encompasses single and multiple surface treatments, as well as sand seals. Additionally, CRS-1 is well-suited for tack coat application.
OTHER APPLCATIONS INCLUDE1:
- Ensuring a strong bond between existing and new bituminous surfaces
- Coating and bonding loose mineral particles on the surface layer
- Sealing surface pores to enhance water resistance
- Providing structural stability and preventing lateral movement of the layer
- Assisting adhesion between the base and superimposed surface course
Tack coat application involves a light spray of Bitumen Emulsion, either by hand or machine. Its purpose is to ensure a reliable bond between an old and a new bituminous surfacing layer. Typically, the tack coat is applied thinly and evenly across the entire surface.
GUIDELINES FOR APPLYING BITUMEN EMULSION CRS-1
TO ENSURE SUCCESSFUL APPLICATION AND OPTIMAL RESULTS, PLEASE ADHERE TO THE FOLLOWING GUIDELINES:
- Clean, Prime, and Tack: Thoroughly clean the pavement surface before applying CRS-1. Properly prime or tack the surface to promote adhesion.
- Weather Considerations: Avoid applying CRS-1 if there is a possibility of precipitation. Moisture can affect the performance of the emulsion, so it is crucial to choose suitable weather conditions for application.
- Application Temperature: For precise application temperature guidelines, it is recommended to consult with a knowledgeable RAHA OIL Marketing representative. They can provide you with specific temperature recommendations to ensure the emulsion performs effectively.
By following these guidelines, you can optimize the application process and achieve the desired outcomes with Bitumen Emulsion CRS-1.
DESIGN GUIDELINES
TO ENSURE SUCCESSFUL OUTCOMES, IT IS ESSENTIAL TO FOLLOW THESE DESIGN GUIDELINES:
Formulating Designs: Prior to initial production and whenever there are changes in aggregate sources, designs should be carefully formulated. This ensures consistency and quality in the final product. It is also recommended to conduct testing to validate the effectiveness of the seal. For comprehensive design services and product quality analysis, RAHA OIL Technical Services is available to assist.
Pothole Patching: When repairing potholes in pavement, it is crucial to follow these steps:
- Tack Coating: Apply a tack coat around the edges of the pothole to establish a strong bond between the asphalt edge and the patching material.
- CRS-1 Application: Apply a uniform coating of CRS-1 to all sides of the pothole, ensuring an approximate coverage rate of 0.20 to 0.25 liters per square meter (0.04 to 0.06 gallons per square yard).
Spray Patching: Spray patching is an effective method for repairing deteriorated areas on the pavement surface. It involves the following steps:
- Alternate Application: Apply CRS-1 and aggregate alternately to restore the damaged sections of the pavement surface. This method can also be used to repair depressions caused by rutting or ravelling.
- Enhanced Adhesion: The excellent adhesion properties of CRS-1 contribute to longer-lasting repairs, ensuring enhanced durability.
Single and Multiple Chip Seals: For surface treatments that offer improved resistance to rutting and low-temperature cracking, follow these guidelines:
- Controlled Application: Carefully apply CRS-1 asphalt emulsion to a well-prepared surface, followed by a controlled application of single-sized, washed chip aggregates. The aggregate sizes should range from 6 mm (¼ in) to 19 mm (¾ in).
By adhering to these guidelines, you can achieve durable and longer-lasting surface treatments using CRS-1, providing enhanced performance and protection against various road-related challenges.
STORAGE AND HANDLING
TO ENSURE OPTIMAL STORAGE AND HANDLING CONDITIONS FOR CRS-1, PLEASE FOLLOW THESE GUIDELINES:
- Storage in Bulk Tanks: It is recommended to store CRS-1 in vertical bulk tanks. This minimizes the surface area and helps maintain the quality of the product.
- Avoid Freezing or Boiling: CRS-1 should never be exposed to freezing or boiling temperatures as it can lead to the breakdown of the emulsion. Maintain safe storage temperatures ranging from 10°C (50°F) to 85°C (185°F).
- Regular Mixing: In bulk storage, it is important to mix CRS-1 every 1 to 2 weeks, especially in colder weather conditions. Use equipment such as a paddle agitator (slow), loose gear pump, slow centrifugal pump, or any suitable low shear pump for effective mixing.
- Avoid Excessive Foam: Do not agitate CRS-1 by bubbling air through it as this can generate excessive foam and potentially cause the emulsion to break down.
- Use Clean Storage Containers: Always ensure that the storage containers are clean and free from any contaminants. It is crucial to verify that the previous contents of the containers are compatible with CRS-1 to prevent any potential emulsion breakdown.
- Approved Containers for Sampling: When sampling the emulsion, make sure to use only approved and sealed containers. This ensures the integrity of the sample and maintains the quality of the CRS-1 emulsion.
By following these storage and handling guidelines, you can effectively maintain the quality and performance of CRS-1 for your applications.
