The Effect of Iron Powder Waste as a Replacement of Amount of Fillers on HRS (Hot Rolled Sheet)

Abstract

Hot Rolled Sheet (HRS) HRS is used on roads with moderate traffic loads, Hot Rolled Sheet is flexible and has high durability, this is due to the mixture of HRS with lame gradations having a large cavity in the mixture, so as to absorb the amount of asphalt large amounts (7-8%) without bleeding, due to the nature of the HRS above, the author chose the HRS pavement type to be modified so that the stability and flow values increased. This study was aimed to determined how much influence iron waste have on stability and flow. This study was used an experimental method that is with a laboratory experiment to get the results, thus the effect of the utilization of iron powder waste on HRS (hot rolled shett) pavement with variations of 0%, 5%, 10%, 15%, and 20% of filler weight. From the results of this study was found that: Iron powder based on gradation and specific gravity test and water absorption has fulfilled the requirements as fillers as regulated in SNI 03-4142-1996. From the Marshall test data obtained, variations that meet the requirements for the properties of Marshall parameters for HRS-WC pavement are variations of 5% and 10%. Percentage of addition of iron powder variation from filler weight which results in the highest stability and flow and fulfills all characteristics the Marshall parameter is a variation of 10%.
