Provided is an asphalt binder composition, and more particularly, an 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.

A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.

Digesting poly(ethylene terephthalate) includes combining poly(ethylene terephthalate) with a solvent that includes one or more long chain alcohols to yield a reaction mixture, and heating the reaction mixture to a temperature between about 20 C. and about 300 C. to yield a product including one or more alkyl terephthalates. A modified asphalt includes asphalt, an asphalt binder, molten polyolefin, and the one or more alkyl terephthalates

An adhesive bituminous sheath for building includes bitumen and an adhesivizing additive mixed with the bitumen, wherein the adhesivizing additive is an aliphatic and cycloaliphatic resin.
