Bitumen & Asphalt Additives | Pavement Maintenance Chemicals
Product Overview
We supply three series of high-performance, eco-friendly asphalt and bitumen additives for road construction and pavement maintenance, covering anti-rutting, anti-stripping and cold patch repair. All chemical additives adopt polymer modified formulas, solving common pavement problems such as high-temperature rutting, water stripping, aging damage and low-temperature failure. They effectively improve pavement stability, extend road service life and reduce overall maintenance costs for various traffic infrastructure projects.
1. Asphalt Anti-Rutting Agent
Core Function: Solve high-temperature pavement rutting, sinking and deformation under heavy traffic.
Key Features
- Improves high-temperature stability, preventing asphalt softening in hot weather
- Enhances pavement compression and wear resistance for heavy-load roads
- Delays asphalt aging and extends pavement service life by 10–15 years
- Eco-friendly formula, suitable for new road construction and old road renovation
