To provide a regenerative additive composition for drainage pavement which enables pelletization to small particles, excels in handling properties, and enables quick and uniform dispersion in an asphalt material-mixing plant, by the addition of an additive composition having low tack and being less prone to blocking.
The regenerative additive composition for a deteriorated asphalt used in drainage pavement is obtained by compounding 100 pts.wt. heavy oil having a flash point of ≥240°C and an aromatic content (% CA) of 10-30% CA, 10-150 pts.wt. thermoplastic elastomer having a styrene content of 5-50 wt% and an MFR (200°C, 5 kg) of ≤40, and 10-40 pts.wt. synthetic wax having a molecular weight of 800-5,000, heat-mixing the resulting compound, and molding the obtained compound to pellets having a particle diameter of ≤50 mm.
