Usage oflron Sludge As Filler in ACWC 20 Mix

Chemical processes produce waste, and waste has to be disposed of, which costs money. Creating
more efficient processes is one way that waste can be minimized and money saved. But another
strategy is to use the waste material as part of industry activities. This research project studies the
effects of the iron sludge from Groundwater Treatment Plant as filler in asphaltic pavements
substituting the cement. Considering the high percentage of iron sludge produced in every
Groundwater Treatment Plant, hence it is very important that the iron sludge can be recycled and
used in pavement construction. The objective of this research is to produce at least the same
performance of the conventional asphaltic pavement by using iron sludge as filler replacing the
cement. The high cost in cement industry nowadays also becomes one of the factors that this
research is conducted since by replacing the iron sludge as filler would decrease the cost of
asphaltic pavement. The scope of this research is mainly to compare the performance of the
modified mix with the conventional ACWC 20 mix. Based from the laboratory testing results, it
shows that the modified mix that using iron sludge as filler have achieved better performance
compare to the conventional ACWC 20 mix.
