Description
Summary:The natural rock asphalt which available in abundance in the southeast of Buton Island, Indonesia was attempted to use in the production of cold mix asphalt. The purpose of this study is to replace petroleum bitumen with local materials such as natural rock asphalt. Small granular size of natural rock asphalt that referred to Buton granular asphalt (BGA) was blended with petroleum bitumen as droplet phase in the asphalt emulsion mixture. Mixture with 8.8% of asphalt emulsion mixture made with the cationic slow setting (CSS) that corresponded to the residue asphalt emulsion content was used as a mixture control. At residue asphalt emulsion content, bitumen of BGA was used for petroleum bitumen partial replacement in the asphalt emulsion mixture production. Test result revealed that utilizing BGA in asphalt emulsion mixture has proved for improving stability where the stability of all mixture with BGA super passed the stability of mixture without BGA.
