Effect of using waste iron powder as filler on asphalt mixture properties

الملخص EN

The reuse of industrial waste in all areas of life, including the construction of roads, has recently become popular.

The type of waste used in the roads may van between plastic waste, chemical waste, iron manufacturing waste (steel slag or iron fillings), or reclaimed asphalt pavements...

etc.

This research is performed to study the effect of using Iron Waste Powder (IWP) in asphalt mixtures as a portion of mineral filler (limestone dust).

Four models with different (IWP) percentages were examined by Marshall Test to determine the effect of this additive on the asphalt mixture properties and these percentages of (IWP) contents, namely; 25%, 50%, 75% and 100% as a replacement of the weight of the mineral filler.

Test results showv that 50% of (IWP) will improve stability and flow, where the stability are increased about 24% and the flow also increased about 18% compared to the reference asphalt mixture.
