Improving the Properties of Asphalt Concrete Mixtures Using Iron Filling Wastes

Abstract

The iron filling powder is a byproduct that can be obtained during steel manufacturing. Using iron filling powder in road paving can have many environmental advantages, such as keeping a clean environment and saving natural construction materials. The paper evaluates the impact of utilizing iron filling powder on indirect tensile strength and Marshall Stiffness of hot mix asphalt. Four values of hot mix asphalt with various iron filling contents, namely, 0, 30, 60, and 90% by weight of total mix, were deliberated. The testing showed an improvement in different Marshall Properties and indirect tensile strength of hot mix asphalt modified with iron filling. As the iron filling percent excesses, Marshall Stability and indirect tensile strength of the studied blends excesses. This is an indication of mixtures performance improvement and the fact that iron filling powder can be utilized in asphalt paving for ecological features. The research was set up to examine the approval of using iron filling to improve the designing attributes of domestic-made bitumen concrete (A.C.) blends. The examination began by estimating the substance and physical qualities of the iron filling. From that point 0, 30, 60, and 90% of the limestone total in the A.C. blends were snubbed by iron filling. The advancement made the iron exhibition a decision in roundabout elasticity, flexible modulus, rutting obstruction, and weariness life. It was discovered that subbing 90% of the coarse limestone total by iron filling upgraded the mechanistic qualities of A.C. blends.
