ADDITION OF COLD ASPHALT MIXTURE STABILITY USING CEMENT FILLER

Abstract

The objectives of this research are (1) To know the influence of usage of filler cement to optimum water content at the time of mixing and compaction of cold asphalt mixture.(2)To know the influence of usage of filler cement to optimum asphalt content of cold asphalt mixture (3)To know the increasing of cold sphalt mixture stability by using cement filler. Research was done by making 5 various of cement filler in cold asphalt mixture dense graded with emulsion asphalt CSS-1 as binder material. Base on research result it can be concluded as follows (1) Addition of cement filler decreased the optimum water content at mixing and compaction time.(2) Addition of filler cement initially degraded the optimum asphalt content but improved the stability. The optimum of cement filler is 4.5 % by weight of aggregate. At this cement filler content the optimum residual asphalt content is 4,8 % with dry stability 850 kg and 4 days soaking stability is 990 kg (3) Cement filler improved dry stability around 67 % and 4 days soaking stability about 130 %
