A composition of matter is described characterized by its qualities to adsorb scents present in gas, liquid and solid matter phases, while simultaneously serving as a carrier for an active ingredient or combination of active ingredients. The composition may also include an additive. The active ingredients are simultaneously and/or independently released gradually by the carrier, or a combination of carriers.

Provided herein is an asphalt binder composition, and more particularly, an amine-containing asphalt binder composition capable of improving mixability between an asphalt binder and an aggregate, and compactibility and water resistance of an asphalt paving mixture. More particularly, the present invention relates to an asphalt binder composition capable of being used in hot mix asphalt for improving workability and/or stripping-resistance, warm-mix asphalt, recycling of reclaimed asphalt pavement, or the like.
