Bitumen modification enhances the performance of asphalt by improving its elasticity, durability, and resistance to temperature variations. Modified bitumen, often incorporating polymers or additives, increases the binder’s adhesion properties and reduces susceptibility to cracking and rutting. This results in longer-lasting pavements with better performance under heavy traffic and extreme weather conditions. Additionally, modified bitumen can improve workability during application, leading to more efficient construction processes and overall enhanced pavement quality.
