Porous hot mix asphalt (PHMA) allows runoff to infiltrate through the pavement. Cured carbon fiber composite materials (CCFCM)s from aerospace production lines were ground into three size groups (Fine, Medium, and Large) reused as reinforcement agents for PHMA in comparison commercial synthetic fiber. The Fine CCFCMs premixed with liquid binder performed best reinforce terms of indirect tensile strength cracking resistance at both 25 °C −10 °C. addition fine fibers reduced porosity by 17% infiltration rate up 20%, while showed prevent draindown an elevated temperature. reinforced rutting resistance.
