Empirical evaluation of the use of oily sludge as a modifier of Buton rock asphalt in hot mix asphalt pavement

Oily sludge is a waste product from the activity of mining, transporting, storing, and refining of petroleum crude oil. It is categorized as hazardous waste; therefore its handling is expensive and should abide by the environmental regulation. The oily sludge consists of three main substances i.e. oil, water and mineral. In this study, the oily sludge is used as the softening agent for the bitumen of Buton-rock-asphalt which has penetration as low as 4 dmm. In order to dissipate the water and volatile fraction of oil, the oily sludge is preprocessed by heating up to 120 degrees Celsius. An amount of petroleum bitumen is added to fulfill the current specification of modifier for Buton-rock-asphalt. The mineral of the sludge is maintained and will be considered as part of the filler of the asphalt concrete mixture. The laboratory study indicates that characteristics of asphalt concrete which made of oily sludge modified Buton-rock-asphalt can be equivalent to the conventional asphalt concrete. This finding is confirmed by a two year observation of the full scale field trial.
