Since porus asphalt mixture has large air void, the aging of high viscous modified asphalt in this pavement significantly progresses in short period. It often degrades as 10 (1/10mm) of penetration grade in 5 to 7 years after construction. In this report, the aging of high viscous modified asphalt was studied and It was clarified that refilling of oil/modifier component is necessary to recover. Then, it was find out that SBS emulsion with good dispersion is effective to be used as modifying additive for recycling. Also, modification of SBS emulsion improves compatibility of high viscous modified asphalt.
