采用废橡胶粉、脱硫石膏制晶须以及地沟油等多元废弃物制备的添加剂在技术方面达到了SBS、胶粉改性沥青及沥青混合料效果,改善沥青延度与软化点、沥青混合料动稳定度等技术指标幅度显著;在经济环保效益方面,多元废弃物制备添加剂既减少沥青混合料用油量1wt%左右,又为大规模处理废轮胎、脱硫石膏及地沟油等固液态废弃物提供了方向。
Adopting waste rubber powder, gypsum desulfurized gypsum and waste residue of waste oil and other additives prepared in the technology to achieve SBS, rubber powder modified asphalt and asphalt mixture to improve the asphalt ductility and softening point, asphalt mixture Stability and other technical indicators significant range; in economic and environmental benefits, the preparation of multiple waste additives not only reduce the asphalt mixture of about 1wt%, but also for large-scale processing of waste tires, gypsum and waste oil and other solid-liquid waste to provide The direction.
