The characteristics of modified asphalt mainly include high-temperature stability, low-temperature crack resistance, durability, skid resistance, environmental friendliness, good anti-aging performance, excellent high-temperature resistance, water resistance, and strong adhesion.

1. High-Temperature Stability: Modified asphalt has a high softening point and viscosity, maintaining good stability at high temperatures without softening or flowing easily. It is suitable for road paving in high-temperature environments, ensuring surface smoothness and rut resistance.

2. Low-Temperature Crack Resistance: Modified asphalt exhibits good elasticity and toughness in low-temperature environments, effectively preventing cracks and maintaining surface smoothness and skid resistance.

3. Durability: Modified asphalt can withstand long-term effects of natural environments and vehicle loads, resisting aging, wear, and peeling. It maintains good performance and service life over extended use.

4. Skid Resistance: Modified asphalt provides excellent friction and grip, enhancing vehicle safety and comfort, especially on rainy or wet surfaces where its anti-skid performance is more pronounced.

5. Environmental Friendliness: The production and application of modified asphalt are relatively environmentally friendly, capable of replacing some traditional asphalt materials, thereby reducing environmental pollution and resource waste.
