Characteristics of Rejuvanated Bitumen with Used Lubricating Oil as Rejuveneting Agent (original) (raw)

2011

Abstract

World wide motor vehicles require million of gallons of lubricating oil. The used lubricating oil generates waste disposal problem because improperly disposed of used oil may contaminate the environment. On the other hand, each year billions of dollars are spent on the road maintenance and rehabilitation. Reclaimed asphalt pavement is among the best option for road maintenance in term of construction sustainability. The technique requires the use of asphalt rejuvenator to revive the aging bitumen. A study is carried out to assess technical viability of using used lubricating oil as rejuvenator. The study aims (i) to identify the properties of typically available used lubricating oil and the requirement for standard bitumen rejuvenating agent; (ii) to determine appropriate methods to improve the characteristics of used oil in fulfilling the rejuvenator standard and (Hi) to assess the laboratory performance of reclaiming asphalt with used lubricating oil as rejuvenator. Only the first...
