PERFORMANCE ON COAL BOTTOM ASH IN HOT MIX ASPHALT

The research conducted is Performance on Coal Bottom Ash in Hot Mix Asphalt. The purpose of this research is to Performance on Coal Bottom Ash applications as aggregates in road bases, sub-bases and pavement. This study focused in three parts objectives in determining the stability of asphalt mixture that is mixed with a certain percentage of bottom ash using Marshall Method, determining physical properties of bottom ash when mixed with asphalt and determining the quality improvement of the Marshall cube in terms of appearance and texture. This study is basically conducted by experimental work and finally resulted in graphical plots. Coal Bottom Ash is obtained from Tanjung Bin Power Plant and laboratory test for this research is conducted at IKRAM Pavement laboratory. Coal Bottom Ash content specimen has high stability and has a good surface texture. Further research can be conducted to identify pavement with coal bottom ash under Tropical weathering and to increase the design life span of pavements. Of waste materials which are industrial wastes like coal ash policies Coal Bottom Ash span stone used by plants in the country to generate of electricity coal combustion is the result of coal ash policies are not used and discarded without producing any harm. The result of Marshall Test and Resilient Modulus was compared between samples. From the experimental results, the use of coal bottom ash meets the specification as stated in SPJ/JKR/rev2008 even though there is a slight difference in the parameter value. From the results obtain in this research, bottom ash can be considered as one of the alternatives to modify HMA properties but further research on the abilit
