Experimental Study On Stability Of Emulsion Asphalt Mixture Made With Extracted Bitumen Of Buton Natural Rock Asphalt (EB-BRA)

Buton natural rock asphalt (BRA) consists of 30% of bitumen and 70% of mineral. Extracted bitumen of BRA (EB-BRA) was blended with cationic emulsion, kerosene, chloride acid, calcium chloride and water to produce asphalt emulsion. Marshall specimens were used to study the stability of emulsion asphalt mixture containing EB-BRA. The test showed that the application of asphalt emulsion made with EB-BRA in the production of asphalt concrete wearing course mixture result in a proper stability. Furthermore, the increasing of curing time led to stability development and flow decline in all asphalt emulsion mixtures Keywordsó Asphalt emulsion, Extracted bitumen of Buton natural rock asphalt (EBBRA), Stability, Flow.
