This study was conducted to determine the effect of warm mix (WMA) modifiers on asphalt mixes containing high percentages of reclaimed asphalt pavement (RAP). Mixes were created using three aggregate sources, four RAP percentages (0%, 20%, 35%, and 50%), and three warm mix modifiers (HMA, zeolite, and Sasobit®). Base binders from the same source (PG 64 -22, 58 -28, 52 -28) and one rejuvenator were used for each mix to ensure the final blended binder grade was at least PG 64 -10.
Specimens were created at HMA or suggested WMA temperatures and tested for rut depth, indirect tensile strength (ITS), …
