LVJIAN® Anti-Rutting Agent is an asphalt mixture additive composed of multiple polymers. Through multiple mechanisms including tackification, reinforcement, filling, asphalt modification, and elastic recovery on aggregate surfaces, it significantly improves the high-temperature stability of asphalt mixtures, while also enhancing moisture stability and low-temperature crack resistance. |

Interlocking Effect
The Anti-Rutting Agent softens during construction due to high temperatures. These particles undergo thermoforming during compaction, effectively acting as single-sized fine aggregates with high adhesion that fill and interlock into the voids of the aggregate skeleton. This enhances the skeleton effect of the asphalt mixture structure, strengthens inter-particle interaction, creates denser mixtures, reduces pavement permeability, and increases the load-bearing capacity of the asphalt mixture.
Reinforcement Effect
The micro-crystalline regions formed by polymers in the Anti-Rutting Agent possess considerable stiffness. During mixing, some portions draw into plastic fibers, forming a bridging and cross-linking effect within the aggregate skeleton that creates fiber reinforcement. The presence of polymer fibers forms a network within the binder, strengthening the interaction and integrity of the asphalt-mineral filler binder system.
Binding Effect
When the Anti-Rutting Agent is added to the asphalt mixture mixing drum at 170–180°C, it first softens through dry mixing with mineral aggregates. After asphalt is added and mixed, the anti-rutting agent particles form a binding effect with the asphalt, improving asphalt properties. It increases the asphalt's softening point, reduces temperature susceptibility, and enhances the adhesion between asphalt and mineral aggregates.
Deformation Recovery Effect
The elastic components of the Anti-Rutting Agent provide elastic recovery for pavement deformation at higher temperatures, thereby reducing permanent deformation in the finished asphalt pavement.
