How does natural rubber modified bitumen impact performance in modified asphalt or bitumen applications?

Natural rubber modified bitumen enhances the performance of asphalt by improving elasticity, durability, and resistance to cracking. The incorporation of natural rubber increases the viscosity and adhesion properties of the bitumen, leading to better performance under varying temperatures and loads. This modification also helps in reducing the susceptibility to aging and oxidative damage, ultimately extending the lifespan of asphalt pavements and improving their overall performance in various environmental conditions.
