Abstract: 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.

Abstract: A high quality asphalt containing pitch is generated as a by-product in a solvent deasphalting process and a method of preparing the same. The pitch is obtained by subjecting a mixture comprising a first vacuum residue and a first petroleum distillate, which is lighter than the vacuum residue and has high amounts of aromatic and resin, to solvent deasphalting. The operation conditions of the solvent deasphalting process are appropriately controlled, such that aromatic and resin components contained in the atmospheric residue and vacuum residue can be distributed to the pitch, and as well, a saturate can be removed.
