Asphalt Repair Agent Is a Chemical Compound
Asphalt Repair Agent is a chemical compound specifically designed to address the deterioration and damage of asphalt surfaces, such as aging, cracking, raveling, and web cracking. Here is the core description of this product:
1. Penetration and Bonding: Asphalt Repair Agent penetrates the pores and micro-cracks within asphalt concrete, chemically reacting or physically bonding with the existing asphalt materials. This process fills cracks, repairs potholes, and restores the road surface's smoothness and integrity.
2. Activation and Supplementation: The high molecular weight activators within the repair agent rejuvenate aged asphalt, restoring its original adhesive and waterproof properties. It replenishes the asphalt components lost due to aging, enhancing the road surface's wear resistance, anti-slip properties, and resistance to water damage.
3. Self-Healing Capability: Incorporating self-healing properties, the repair agent can arrest the evolution of micro-cracks into macro-cracks, restoring the pavement's strength. The self-healing process is influenced by the rest period, type of healing material, level of strain, and temperature.
4. Healing Agents: The agent can be incorporated into asphalt through encapsulating methods such as microcapsules, hollow fibers, and microvascular fibers. Upon crack formation, the encapsulating medium opens, releasing the healing agent that repairs the cracks.
5. Hybrid Self-Healing Technologies: Recent developments include hybrid systems that combine rejuvenation and heating. These systems use induction heating as a damage repair mechanism while capsules rejuvenate aged asphalt, restoring its properties. The increased temperature from induction heating can also accelerate the diffusion process of the rejuvenator into aged asphalt.
6. Sustainability and Service Life: The incorporation of self-healing properties into asphalt pavements is an effective technique to increase its service life and achieve sustainable pavements. This approach not only reduces maintenance costs but also minimizes traffic hindrance and environmental impact.
In summary, Asphalt Repair Agent is a comprehensive solution for the maintenance and repair of asphalt surfaces, offering a combination of immediate repair and long-term self-healing capabilities to extend the life of pavements and reduce the need for frequent and costly repairs.
