    • PROBLEM TO BE SOLVED: To provide an additive composition for asphalt, which improves a separation-preventing effect between the asphalt and aggregates and can instantaneously develop the effect.
      SOLUTION: This additive composition for the asphalt is characterized by comprising (A) 100 pts.wt. of a specific acidic phosphoric acid compound and (B) 50 to 300 pts.wt. of a mineral oil, and having a viscosity of ≤2,000 mPa s at 25°C. An asphalt composition is characterized by adding the additive composition for the asphalt in an amount of 0.05 to 3.0 wt.% based on the asphalt.
