Paragraph starter
The research by Jiang et al. (2020) highlights the significant potential for resource utilization of silicone rubber from scrapped composite insulators. Their findings demonstrate that pulverized silicone rubber can be effectively incorporated into asphalt mixtures (15%-18%), used to modify waste rubber powder with EPDM (10%), and serve as a substantial aggregate (over 40%) in non-slip coatings. This approach offers a promising solution for managing landfill waste and creating valuable secondary materials, aligning with principles of circular economy and sustainable design.
