Study on the characteristics and performance of nano
To address this issue, this paper developed a novel WAL material by compositely modifying asphalt with nano-silica (NS) and unsaturated polyester resin (UPR).
In modern transportation infrastructure, asphalt, as a critical road material, directly impacts the service life and safety of pavements. With advancements in technology, modified asphalt techniques have emerged, enhancing traditional asphalt by incorporating specific modifiers to improve high-temperature stability, low-temperature crack resistance, and adhesion to aggregates, thereby upgrading overall road performance. Among these, APP (Acrylic Polymer)-modified asphalt stands out in the field due to its unique modification mechanisms and superior comprehensive properties.
The resin-like characteristics of APP-modified asphalt stem from its distinctive molecular structure. Resins are typically high-molecular-weight compounds composed of long carbon chains, known for their chemical stability, thermal resistance, and electrical insulation. Similarly, the polymer components in APP-modified asphalt integrate into the asphalt matrix, interacting synergistically to enhance its properties.
Firstly, from a physical perspective, resins exhibit exceptional heat and cold resistance. Analogously, APP-modified asphalt maintains structural stability under high temperatures, resisting softening or degradation, while retaining toughness in low-temperature environments to prevent brittleness. This dual resistance enables APP-modified asphalt to perform reliably under extreme weather conditions, extending road longevity.
Secondly, resins’ complex molecular structures confer strong chemical stability. The polymer components in APP-modified asphalt similarly resist chemical corrosion from oils, acids, and other substances. This stability ensures road safety during use and simplifies maintenance efforts.
Thirdly, resins’ ordered molecular structures often yield excellent electrical insulation. APP-modified asphalt shares this trait, reducing current leakage during pavement application and improving the reliability of electrical systems.
Beyond these traits, APP-modified asphalt demonstrates superior adhesion. Compared to conventional asphalt, its polymer content adheres more effectively to aggregate surfaces, ensuring smooth pavement and mitigating water damage. Additionally, its construction-friendly properties—such as ease of heating, mixing, and compaction—streamline road building and maintenance.
the resin-like behavior of APP-modified asphalt arises from its high-polymer content. These polymers remain stable at high temperatures, flexible at low temperatures, and offer enhanced chemical resistance, electrical insulation, and adhesion. Collectively, these properties have driven widespread adoption of APP-modified asphalt in road construction, delivering significant practical benefits. Looking ahead, ongoing technological progress is expected to further optimize its performance, strengthening the foundation for safer and more durable transportation networks.
