摘要
为充分利用废机油残留物(Re-refined Engine Oil Bottom, REOB),改善REOB对环境造成的不良影响,将2种不同来源的REOB掺加到3种不同老化程度的沥青中,对比不同REOB掺量再生沥青的物理流变性能,确定了REOB在老化沥青的适宜掺量。结果表明:REOB可使老化沥青的针入度和延度增大,软化点和黏度降低且在老化沥青质量15%~20%的掺量下对老化沥青的再生效果最佳。
In order to make full use of the re-refined engine oil bottom(REOB)and improve the negative impact of the REOB on the environment,two kinds of REOB from different sources and contents were mixed into three kinds of asphalt with different degrees of aging,comparing the physical performance of REOB recycled as-phalt with different content,the appropriate content of REOB in the aging asphalt was determined.The results show that REOB can increase the penetration and ductility,decrease the softening point and viscosity of aged asphalt,and the regeneration effect of aged asphalt is the best when the content of REOB is 15%~20%.
