Asphalt modifiers are mainly used to improve the road performance of asphalt and asphalt mixtures. By overcoming the temperature sensitivity of ordinary asphalt, they enhance its durability and stability in extreme environments. Core Functions:
Improving High-Temperature Stability: Significantly reduces permanent deformation at high temperatures, enhances rutting resistance, and prevents pavement from flowing and deforming under hot weather or heavy loads.

Enhancing Low-Temperature Crack Resistance: Improves the flexibility and elasticity of asphalt in low-temperature environments, effectively resisting low-temperature cracking and reflective cracking.
Improving Durability: Enhances anti-aging and anti-fatigue capabilities, extends pavement service life, and improves the adhesion between asphalt and aggregates and its resistance to water damage.
Regulating Temperature Sensitivity: Reduces the temperature sensitivity of asphalt, maintaining stable performance over a wide temperature range.
Application Scenarios:
Road Traffic: Widely used in high-grade highways, heavy-load traffic sections, airport runways, bridge deck paving, and intersections, among other special applications. Building waterproofing: Used for roof waterproofing projects in high-end buildings, producing modified bitumen waterproof membranes and coatings to withstand large displacements and harsh climatic conditions.
Common types: Includes various materials such as polymers (e.g., SBS, EVA), rubber, resins (e.g., polyethylene, coumarone resin), and inorganic fillers.
