Abstract

Major concern of today's world is on environmentally treatment of wastes. Wastes such as pulverized fly ash (PF A), blast furnace slag, kiln dust, steel slag ash, and etc are increasing rapidly due to the growing production volume in the industry. These waste materials have been recycled and used in construction industry for decades of years. In Malaysia, according to the 8th Malaysia Plan, it is estimated that Malaysia will use up 11.2 million tonnes of coal per annum. This will generate more than 2 million tonnes ofPFA annually. Even though there is abundant ofPFA in Malaysia, only a small percentage of the PF A is utilized for construction purposes. Main development in this country is focused on the construction of road which cousumes a huge amount of materials both raw and processed so if waste products can be used as a substitute to the constituent of asphalt mix design, a more economical asphalt mix can be produce while at the same time solving the problems of disposing waste products. In this study, pnlverized fly ash will be replacing the normal filler of quarry dust or Ordinary Portland Cement (OPC) in the asphalt mix. The objectives of this study are to determine the effect ofPFA application in asphalt concrete and to obtain· an optimum compaction effort for the mix design. Two sets of asphalt specimeus with the respective mineral filler of Ordinary Portland Cement (OPC) and the pnlverized fly ash were prepared with different compaction effort and tested using Marshall Mix Test. As a conclusion, the results showed that the substitution of OPC with PF A gives a better performing asphaltic concrete in stability, flow, Marshall Stiflhess, and air voids at a lower compaction effort.
