The stability of bituminous mix design using various types of fillers / Ahmad Fadhley Abdul Majid

Road construction and maintenance contribute significantly to the growth of
Malaysia’s economy. At present, the awareness among the government agencies and
contractor in pavement technology in order to improve the pavement systems is
responding well. Therefore, the road system exactly is essential for nation’s
development and growth.
This research focuses on the Ordinary Portland cement (OPC) and quarry dust as
fillers in order to determine the optimum percentage in the mix bituminous design.
Design mix that contain with 4%, 6%, 8% and 10% of fillers will be tested by using
Marshall Test in the laboratory to determine its characteristics and the used in the
bituminous mix design. In order to achieve the main objectives, the properties of the
other material such as aggregate and bitumen will be firstly measured and
determined.
After the research, the maximum stability of quarry dust and Ordinary Portland
cement is 12.99kN and 13.83kN respectively. The highest stability of mix design
occurred at the maximum percentage of filler which is 10%. The optimum
percentage of quarry dust is 8% and OPC is 10%.
