Asphalt rejuvenator is an additive system that restores the rheological balance of aged bitumen recovered from reclaimed asphalt pavement (RAP). The formulation supported by FangService adopts a 3-in-1 approach - it works simultaneously as a warm-mix agent, a performance modifier and a chemical rejuvenator - so that recycled mixes can reach high RAP incorporation without sacrificing workability or long-term durability.
The mechanism rests on molecular de-crystallization and chemical regeneration: targeted agents cleave and depolymerize the brittle oxidized fractions of aged bitumen, while a steric-hindrance resin suppresses re-crystallization and keeps the regenerated binder stable; a latent reactive component then builds a three-dimensional cross-linked network that reinforces the mix structure at medium mixing temperatures of 120-140 C.
