Description
Summary:The use of reclaimed asphalt pavement (RAP) has been becoming one of the best solutions to preserve natural resources in the construction sector. However, the stiffness property of aged asphalt resulted from the RAP is considered as the main obstacle in the field application. Nevertheless, waste engine oil (WEO), as one of the most common rejuvenating agent, has been used for renovating the characteristics of aged asphalt. This paper presents a review of the previous research works conducted on the rejuvenating of aged asphalt using WEO, including its benefits, drawbacks and its adverse side effect. It was observed that the inclusion of WEO as a rejuvenating agent gives positives and negatives influences on the attributes of aged asphalt. Therefore, an integration of WEO with other modifiers might be beneficial for renovating the performance of aged asphalt at both low and high temperatures. The results of this review can be used to predict future challenges in the renovation of aged asphalt using WEO.
