    Abstract

    In this study, a physical model for the investigation of the performance of a capillary-barrier system (CBS) made using recycled asphalt was developed. A novel rainfall simulator using a high-pressure misting system was constructed and instrumented. Various intensities of rainfall and different inclination angles were used to study the performance of CBS. The behavior of the capillary barrier during rainfall and drainage observed in this study was consistent with the behavior of capillary barriers reported in previous studies. The lateral diversion percentage was found to have an inversely proportional relationship with rainfall intensity, but a directly proportional relationship with the slope angle. The lateral diversion percentage obtained from combinations of fine and coarse recycled asphalt ranged from 32 % to 61 % of the total rainfall.
