摘要 采用高速剪切法制备废橡胶粉改性温拌沥青,并对添加温拌剂E26和DWMA胶粉的改性沥青进行短期模拟老化试验。研究结果表明,加入温拌剂E26和DWMA改变了沥青四组分的含量,沥青内部结构未发生明显变化;短期老化后,针入度和延度减小,软化点升高;芳香分质量分数降低,胶质和沥青质质量分数增多。对比发现,添加DWMA温拌剂的胶粉改性沥青,老化前后三大指标和四组分变化幅度最小,官能团减小幅度最小,说明抗老化能力优于添加E26和未添加温拌剂的改性沥青。

Abstract: Spent rubber powder modified warm mix asphalt is prepared by high-speed shearing method.The short-term simulated aging test is performed to the modified asphalt added with warm mix agent E26 and DWMA rubber powder, respectively.Research results indicate that the addition of E26 or DWMA has changed the content of four components of asphalt, but has no obvious impact on the internal structure of asphalt.After short-term aging, the penetration and ductility of the asphalt drop while its softening point increase.The mass fraction of aromatics in the asphalt decreases, and the mass fractions of gum and asphaltene increase.Through comparison among the asphalts with E26, DWMA and without any warm mixing agent, it is found that the rubber powder modified asphalt with addition of DWMA warm mixing agent has changed the smallest in three indexes and four components before and after short-term aging, and reduce the smallest in functional groups.It is indicated that the anti-aging ability of the rubber powder modified asphalt with DWMA warm mixing agent is better than that with warm mix agent E26 and without any warm mixing agent.
Key words:  spent rubber powder    rubber powder modified asphalt    short-term aging    warm mixing agent
