Polymer Modified Bitumen 70-28 General Description
Polymer Modified Bitumen 70-28 is a high-performance, paving-grade Bitumen specially designed for use in road construction. It is recognized for its excellent adhesion, durability, and flexibility, making it a critical binder for asphalt mixtures in a variety of infrastructure applications.
Bitumen PG 70-28 is widely utilized in road construction, including highways, streets, and airport runways. Its superior characteristics make it an essential component for the construction of stable, long-lasting, and heavy-duty pavements.
Key benefits:
- Enhanced asphalt performance: improves the resistance of asphalt mixtures to rutting, cracking, and moisture damage, contributing to smoother, safer roads.
- Durability: offers superior performance under heavy traffic loads, ensuring long-lasting infrastructure with reduced maintenance needs.
- Pavement preservation: seals cracks, prevents water infiltration, and rejuvenates worn-out surfaces, reducing the need for frequent repairs.
- Environmental sustainability: made from recycled crude oil refining byproducts, bitumen PG reduces the need for new raw materials and lowers the carbon footprint, contributing to more sustainable road construction practices.
