How does design of recycled asphalt pavements and selection of modifiers impact performance in modified asphalt or bitumen applications?
The design of recycled asphalt pavements (RAP) and the selection of modifiers significantly influence the performance of modified asphalt. Properly designed RAP ensures optimal aggregate gradation and binder properties, enhancing durability and resistance to cracking. The choice of modifiers, such as polymers or rubber, can improve elasticity, temperature susceptibility, and overall performance. Together, these factors contribute to a more resilient pavement structure, extending service life and reducing maintenance needs in modified asphalt applications.
