Differences in the Spreading Temperature between the Grained Buton Bitumen with the Penetration Asphalt 60/70

Abstract

The need for asphalt in Indonesia is so high that every year it has to import asphalt oil around 600,000 tons. The amount of imported oil asphalt can certainly be reduced by the optimum utilization of asbutons. This research study was to determine the influence of temperature differences at the time of the finisher Asphalt Concrete mix asphalt - Binder Course (AC-BC) field with the use of grained Buton Asphalt and bitumen 60/70 penetration, using local aggregate in asphalt mixtures Asphalt Concrete - Binder Course (AC -BC). The method used is a survey of direct sampling to the field. Temperature measurement data is taken on asphalt mixture in asphalt finisher before compacted. Temperature data collection is done for Asphalt Buton Grain type 5/20 and asphalt penetration 60/70 then calculated decrease happened and long time required asphalt carrier vehicle from asphalt mixing plane to the location of an overlay. So we get the difference of temperature decrease. The result showed that the temperature decrease on the asphalt of grain buton was increased, compared to the asphalt mixture using liquid asphalt with approximate time 5 hour trip from asphalt mixing plane to location. So it needs special handling in the field implementation to cope with rapid temperature decline.
