Experimental Study of Permeable Asphalt Mixture Containing Reclaimed Asphalt Pavement

The current focus of research attention on reclaimed asphalt pavement (RAP) utilization is expanding the applications RAP. This study aims to analyze road performance recycled permeable mixtures (RPAMs), which represents a novel direction for utilizing Firstly, Marshall design method was used carry out material composition RPAM with varying RAP contents (10%, 20%, and 30%). Subsequently, different 30%) preheating temperatures (120 °C, 130 140 150 160 °C) tested mixture containing 12% high-viscosity as control group. mixture’s included high-temperature stability, low-temperature crack resistance, water anti-raveling performance, dynamic mechanical properties. results indicate that higher content, better RPAM, while deteriorate. At 30% its comparable group mixture. However, increasing temperature can improve stability but may reduce performance. optimal between °C. modulus test showed greater leading reduced resistance. influence opposite. These demonstrate feasibility paving under controlled content conditions.
