The Feasibility of Using Metallic Waste Swarf in HMA and Its Effect on Marshal Parameters, Rutting and Frictional Coefficient
Author(s):
Abstract:
This research has been done to investigating the effect of three type of metallic swarf including Iron, cast iron and aluminum on asphalt mixture parameters, rutting resistant and the friction coefficient of the asphalt mixtures. In this regard, the amounts of 5,10,15,20 and 25% of each afore said swarf are added to the asphalt mixture and after compacting, the amount of stability, flow, void in the mineral aggregate and void filled with asphalt, unit weight, asphalt binder content and air voids was measured using Marshall Test Equipment. It should be noted that in addition to measuring the above parameters, the Hamburg wheel track test and the friction resistance test were performed to measuring the rutting stability and friction coefficient of the mixtures, respectively. The results of Marshall tests showed that the addition of metallic swarf, especially iron and cast iron, had a positive effects on Marshall parameters, but in different percentages, these additives had a different performance on changing the Marshall parameters. The results of the wheel track test showing that the addition of 5% iron and cast iron has a positive effect on reducing the depth of the rut , but the increase in the percentage of these additives has a reverse function and increases the depth of the rut relative to the base state. Finally, the results of the friction resistance test showed that the addition of metallic swarf increases the frictional coefficients.
