Abstract

The development of new technologies to minimize the effects of climate change action and the high density of traffic on road pavement has been researched in recent years using macromolecules as asphalt binder modifier in the pursuit of getting high performance asphalt mixtures. The objective of this study was to use oily sludge tank background, coming from primary oil processing unit, difficult environmental disposal liabilities as modifier of asphalt cement petroleum, CAP 50/70, and evaluate the stability of storage of binder modified as to phase separation by means of heat and rheological analysis. Due to the difficult dispersion of oily sludge in CAP 50/70, blend rubber tires and oily sludge in the proportion 15/85% by mass was prepared and used in the proportion of 10% by mass, as agent modifier. The results show that the modified binder that meets the Brazilian specifications as to the temperature machining and compaction of hot mix asphalt – HMA type employed in road surface coverings. However phase separation was observed in the modified asphalt binder.
