Modified bitumen refers to bitumen that has been altered through the addition of polymers or other materials to enhance its properties. In asphalt or bitumen modification processes, this definition applies to the use of additives that improve elasticity, temperature resistance, and durability. These modifications help to achieve better performance under varying environmental conditions, reduce susceptibility to cracking, and extend the lifespan of asphalt pavements, making them more suitable for heavy traffic and extreme weather.
