Asphalt Anti-Rutting Additive

Product Position:

Asphalt anti-rutting additive is a high-molecular polymer modifier specially developed for heavy-traffic asphalt pavements, complying with JT/T 860.1-2025 standard. After mixing with hot asphalt mixture, it forms a rigid three-dimensional interlocking network inside the mixture, greatly improving the high-temperature stability, dynamic stability and bearing capacity of asphalt pavement, effectively solving permanent rutting deformation caused by long-term heavy vehicle load. It also balances low-temperature crack resistance and water stability without damaging the original pavement performance.
