Thus, when they can benefit the final product without creating an environmental liability they are often used as additives in HMA. Public agency willingness to fund higher-cost asphalt additives. Modified asphalt cement is usually higher in initial cost than unmodified asphalt cement, but it should provide a longer service life with less

EFFECTS OF VARIOUS ASPHALT BINDER ADDITIVES/MODIFIERS ON

Moisture damage of asphalt concrete is defined as the loss of strength and stability caused by the active presence of moisture. The most common technique to mitigate moisture damage is using additives or modifiers with the asphalt binder or the aggregate. Various additives and modifiers are used to enhance the performance of asphalt mixtures.
