Research Abstract

The use of reclaimed asphalt pavement (RAP) represents a recycling method with environmental benefits along with cost savings. RAP in new combinations of asphalt mixtures has benefits such as lowering the amount of virgin material, reducing cost and natural resources, and causing less environmental harm. In order to improve the physical and rheological characteristics of aged asphalt binders found in RAP, rejuvenators have been used. There are many types of rejuvenators for RAP binders, such as bio-oil, waste engine oil, and waste cooking oil. Foamed and emulsified asphalt have been widely used for their energy-saving and emission-reducing properties for cold mix-in-place (CIR) production. Hot in-place (HIR) recycling does not necessitate the transportation of significant amounts of new materials to the working site, there are fewer traffic noise and delays caused by cars coming and going from the work area. Finally utilizing cement to recycle the surface, base, and subgrade (full-depth reclamation (FDR)) to enhance the structural strength and durability of pavements.
