Hebang Fiber High-Performance Anti-Rutting Agent

Product Overview

Rutting is a pervasive and severe distress in asphalt pavements, especially under high temperatures and heavy traffic loads. The Hebang Fiber Anti-Rutting Agent is a specially engineered polymer-based additive designed to fundamentally enhance the high-temperature stability of asphalt mixtures. By significantly improving resistance to permanent deformation, it provides a cost-effective and reliable solution for constructing durable roads that withstand the test of time and traffic.

Core Advantages

• Superior Rut Resistance: Dramatically increases the dynamic stability of asphalt mixture, effectively resisting deformation under heavy loads and high temperatures.

• Enhanced Cohesion & Binding: Improves the adhesion between asphalt binder and aggregates, reducing moisture susceptibility.

• Fiber Reinforcement: The unique polymer fibers form a reinforcing network within the mixture, increasing overall structural integrity.

• Easy Application: Simply add directly to the mix during the drying cycle. No need for complex equipment.

• Proven Performance: Developed in collaboration with leading research institutes, ensuring reliable results.

Mechanism of Action

• Cohesive Binding: Modifies the asphalt binder, raising its softening point and reducing temperature sensitivity.

• Particle Interlocking: The softened pellets act as fine, high-strength aggregate that fills voids and enhances interlocking.

• Fiber Reinforcement: Polymers stretch into micro-fibers, creating a 3D network that provides tensile strength.

• Elastic Recovery: The elastic components allow for partial recovery of deformation after load removal.

Recommended dosage and process

• Recommended Dosage: 0.3% ~ 0.5% by weight of total asphalt mixture (3~5 kg per ton).

  • Standard Highways: 0.35% - 0.4%

  • Heavy-Duty Traffic: 0.5% or higher.

• Mixing Process:

  1. Heat aggregates to 170–180°C.

  2. Add Hebang Fiber Anti-Rutting Agent and dry-mix for 2-3 seconds.

  3. Add asphalt binder and continue mixing.

Application scope

Ideal for high-stress pavement applications:

• Highways & Expressways

• Bus Lanes & Intersections

• Airport Runways
