| Abstract | ||
| Iron slag powder is a by product that can be obtained during steel manufacturing. Using iron slag powder in road paving can have many environmental advantages such as keeping clean environment and saving natural construction materials. This paper discusses the effect of using iron slag powder on Marshall Stiffness and indirect tensile strength of hot mix asphalt. Three hot mix asphalt with various iron slag contents, namely; 0%, 10% and 20% by weight of total mixture were studied. Laboratory testing showed an enhancement in different Marshall Properties and indirect tensile strength of hot mix asphalt modified with iron slag. As the iron slag content increases, the Marshall Stability and indirect tensile strength of the studied mixtures increases as well. This is an indication of mixtures performance improvement in addition to the fact that iron slag powder can be used in asphalt paving for environmental advantages. | ||
