摘要

再生沥青路面是目前道路建设中常用的一种路面材料。再生沥青路面可以提高环境的可持续性,同时也减少再生路面的处理问题。本研究以废食用油(WCO)为再生材料。有不同的样品,其中样品A为对照混合物,为未加返青剂的原始混合物,RAP含量为0%。样品B为RAP含量为25%和50%的回春RAP混合物与WCO混合,样品C为RAP含量为25%和50%的未回春RAP混合物。另外,样品D是针对100% RAP含量的。因此,为了评价其工程性能,采用了马歇尔稳定性和流动、动态蠕变模量和间接抗拉强度等不同的试验测试,并在此基础上确定了最佳配比。结果表明,掺加再生材料的再生沥青路面的稳定性和抗变形性能均有所提高。间接抗拉强度随RAP含量的增加而增加。综上所述,100%的再生沥青路面为最优值,再生材料可显著提高再生沥青路面的性能,减少污染。

Analysis of Reclaimed Asphalt Pavement with Rejuvenating Materials
Reclaimed asphalt pavement (RAP) is currently commonly used in road construction. Reclaimed asphalt pavement can enhance environmental sustainability while also reducing reclaimed pavement disposal issues. In this study, waste cooking oil (WCO) was utilized as rejuvenating material. There are different samples, where Sample A is the control mixture which is virgin mixture without rejuvenator contain 0% of RAP content. Sample B is the rejuvenated RAP mixtures including 25% and 50% of RAP content combined with WCO, while sample C is the non-rejuvenated RAP mixture containing 25% and 50% of RAP content. In addition, sample D is for 100% RAP content. Therefore, to evaluate the engineering properties, different experimental test, including Marshall stability and flow, dynamic creep modulus and indirect tensile strength are applied, and the optimum percentage was determined based on the result. The findings revealed that reclaimed asphalt pavement with rejuvenating materials enhanced the performance of stability and deformation resistance. Moreover, the indirect tensile strength increases with the increase of RAP content. Based on the findings, it can conclude that 100% of reclaimed asphalt pavement showed the optimum value and significantly enhanced the performance of reclaimed asphalt pavement with rejuvenating materials by reducing pollution.
