Product Details:

1. Introduction

Cold Patch Additive can form a good bonding layer between asphalt and aggregate, prevent water from intruding into the cured cold patch, and improve the overall performance.

When the finished cold patch is applied to a pothole repair, the additives improve the adhesion of the cold patch, and after compaction, the water is removed and sequestered into the adhesive layer. The cold patch and pothole are then bonded together.

2. Function and Features

• Enhanced Bonding: The cold patch additive improves the bonding strength between cold patch asphalt and the road substrate, ensuring the stability of the repaired surface.
• Increased Compressive Strength: It enhances the compressive strength of the cold patch mixture, allowing the repaired road to better withstand vehicle loads and reducing wear.
• Improved Water Resistance: It improves the water resistance of cold patch asphalt, preventing water infiltration that could lead to surface peeling or cracking.
• Enhanced Durability: It increases the oxidation resistance and weatherability of cold patch asphalt, delaying aging and extending the service life of the repaired road.
• Convenient Construction: The cold patch additive does not require heating, making the construction process quick and easy, suitable for emergency repairs.

Example:

• Core Functions:
  • Improves the bonding strength between cold patch asphalt and the road surface to prevent peeling.
  • Increases compressive strength and water resistance, suitable for high-load and rainy environments.
  • Enhances the aging resistance and extends the lifespan of the repaired surface.

5. Materials and Composition

• Main Ingredients: Polymers, modified asphalt, tackifiers, antioxidants, etc.
• Eco-friendly Materials: Uses environmentally friendly raw materials that comply with international environmental standards, ensuring no harmful gases or substances are released during use.
• Manufacturing Process: Produced using advanced polymer modification technology to ensure the product's bonding strength and durability at low temperatures.

Example:

• Material Composition:
  • Polymer-modified Asphalt: Enhances bonding strength, aging resistance, and overall strength of the cold patch asphalt.
  • Tackifiers: Improve adhesion between the cold patch and substrate, ensuring the long-lasting integrity of the repair.
  • Antioxidants: Extend the shelf life of cold patch materials by delaying oxidation and aging.

6. Performance and Advantages

• Quick Construction: The cold patch additive allows for construction without heating, making it faster to apply and ideal for emergency repairs.
• Enhanced Bonding and Strength: Improves bonding strength and compressive strength, ensuring long-lasting repairs.
• Weather Resistance: Increases the product's resistance to oxidation, UV damage, and other environmental factors, extending the repair’s lifespan.
• Eco-friendly and Safe: Meets international environmental standards, with no harmful emissions during use.
• Water Resistance: Offers excellent water resistance, making it suitable for wet environments or rainy regions.

Example:

• Construction Efficiency: Compared to traditional hot-mix asphalt repair methods, the cold patch additive is faster and more efficient, especially in regions with significant temperature fluctuations.
• Durability: Roads repaired with the cold patch additive can extend service life by 20%-30% over traditional cold patch materials.
• Strength and Stability: The repaired road remains stable under heavy traffic loads, avoiding loosening or erosion common with traditional repairs.

Summary

The Cold Patch Additive is a highly efficient additive designed to optimize the performance of cold patch asphalt mixtures. It enhances the bonding strength, compressive strength, water resistance, and aging resistance of cold patch asphalt, making it ideal for road repairs and maintenance. With its quick construction process, environmental friendliness, and excellent durability, the cold patch additive provides a reliable solution for emergency repairs and long-term road maintenance. It is particularly suitable for low-temperature environments and areas with high traffic volume, offering significant improvements over traditional cold patch materials.
