Abstract: This paper presents an experimental work on the evaluation of reclaimed asphalt pavement mixture that was rejuvenated using Jatropha Curcas oil. The amount of Jatropha oil used was four percent of aged bitumen content by weight. Series of strength tests were conducted to evaluate the performance of jatropha oil rejuvenated reclaimed asphalt mixture. The Indirect tensile strength of rejuvenated reclaimed asphalt mixture was found to be 96N/mm2, which is capable of withstanding repetitive traffic loadings imposed on it. Average Marshall flow value of the Jatropha rejuvenated reclaimed asphalt mixture is 4mm, this implies that, the RAP mixture has been rejuvenated by Jatropha oil through the improvement of its ductility without compromising its resistance against fatigue cracks as shown in its average stability value of 456kg. The Jatropha curcas oil rejuvenated reclaimed asphalt pavement has an average tensile strength ratio of 88.6%, this is an indication of the mixture’s resistance to moisture damage.
Keywords: Rejuvenator, Jatropha curcas oil, moisture susceptibility, indirect tensile.
