    摘要:
    為改性老化瀝青,恢復老化瀝青的路用性能,綜合相容性和膠體調和原理,用回收食用油和擴散劑制備滲透型再生劑,對比分析普通型再生劑與滲透型再生劑用量對再生瀝青粘滯性和低溫性能的影響,并采用動態剪切流變試驗測定再生瀝青的車轍因子。結果表明,隨著再生劑摻量的增加,再生瀝青的針入度和延度呈近似的線性增大,軟化點、動力粘度和低溫蠕變勁度則降低;相比于普通型再生劑,滲透型再生劑的再生效果更好,當滲透型再生劑的用量為6%時,再生瀝青的以上性能均可恢復至基質瀝青的指標水平,且再生瀝青具有合適的車轍因子以滿足高溫穩定性的要求。
    Abstract:
    Diffusible rejuvenator was produced with recycled edible oil and dispersant to rejuvenate the aged asphalt and restore its pavement performance based on the principles of compatibility and colloid blending, Effects on the viscosity and low temperature performance of recycled asphalt by contents of common rejuvenator and diffusible rejuvenator were compared and the rutting factor of recycled asphalt determined by dynamic shear rheological test. The results show that the penetration and ductility of recycled asphalt increase approximately linearly with the increase of rejuvenators content, while the softening point, kinetic viscosity and lowtemperature creep stiffness decrease. The regeneration effect of diffusible rejuvenator is better than that of common rejuvenator. When the content of diffusible rejuvenator is 6%, the performance of aged asphalt can be restored to the index level of base asphalt, and its rutting factor proves good enough to meet the requirements of high temperature stability.
