The installation of modified bitumen significantly impacts performance in asphalt applications by ensuring optimal adhesion, flexibility, and durability. Proper installation techniques, such as heating and rolling, enhance the bonding between layers, reducing the risk of delamination and water infiltration. Additionally, correct application methods help maintain the modified bitumen’s properties, such as elasticity and resistance to UV degradation, ultimately leading to longer-lasting pavement and improved resistance to cracking and fatigue under varying environmental conditions.
