SDA Low cost and Hi-performance Asphalt Binder Composition for Asphalt Pavement Using Residue produced during Solvent De-Asphalting Process And Manufacturing Method thereof
SDA Low cost and Hi-performance Asphalt Binder Composition for Asphalt Pavement Using Residue produced during Solvent De-Asphalting Process And Manufacturing Method thereof
The present invention relates to a low-cost and high-performance asphalt mixed composition for asphalt pavement by mixing an asphalt binder composition made using remnants produced through a SDA process (Solvent De-Asphalting Process / solvent deasphalting process or solvent extraction process) And an asphalt mixed composition made thereby.In the present invention, 2 to 8% by weight of an asphalt binder composition produced using the residue of the SDA process; And 92 to 98% by weight of aggregate. The asphalt binder composition according to the present invention is characterized in that the asphalt binder composition contains 100% by weight of the total weight of the asphalt binder composition , 1.0 to 3.0% by weight of at least one material selected from the group consisting of 90 to 95% by weight of residues of the SDA process, 1 to 7% by weight of modifying additives, 0.1 to 1.0% by weight of bonding adjuvant, SBR and SBS, 0.1 to 1.0% by weight of sulfur, and 0.1 to 0.5% by weight of a vulcanization accelerator.
