Design and Production of Steel Slag Warm Mix Asphalt SSWMA Hossein Sheikh Zeinoddin h Sheikhzeinoddin@cv iut ac ir Date of Submission 2012 08 02 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Sayyed Mahdi Abtahi mabtahi@cc iut ac irAbstractLarge energy consumption and increased environmental awareness in traditional method of asphaltproduction Hot Mix Asphalt and more stringent environmental regulations have resulted in the innovationof a production technology named Warm Mix Asphalt WMA In this technology various methods areused to reduce the temperature of production and paving The most two important results of temperaturereduction are decreasion of energy consumption and decreasing emissions of burning fuels fumes andodors generated at the production plant and at the paving site In recent years widespread researches havebeen done to develop new and economical technologies of WMA production As many studies show insome of the production technologies the produced WMA may have low moisture resistance because theaggregates do not loose their moisture completely On the other hand Steel slags are the by product of ironand steel factories that many researches have been done around the world to use this material in severalfields One of these fields is Asphalt Concrete AC Various studies show Steel slag is considerablyeffective in improving the performance of asphalt concrete One of the properties of steel slags is high heatcapacity in comparison to stone aggregate which leads to a higher energy consumption during the processof WMA production The aim of this study is to use WMA technologies in steel slag hot mix asphalt in order to reduce the energyconsumption leading to the production of steel slag warm mix asphalt SSWMA In order to produce steelslag warm mix asphalt an amino based resin which is thermoset is used as an additive to decrease theviscosity of bitumen This resin is used in the amount of 5 10 and 15 by the weight of bitumen Thematerials included one type of binder AC 60 70 Lime stone and steel slag aggregates To assess theperformance of steel slag warm mix asphalt several tests including Marshall tests and moisture sensitivitytests were applied Experimental results show that the addition of poly amin resin can decrease the viscosityof bitumen by producing foam This reduction of viscosity leads to reduce the temperature mix asphalt andsteel slag mix asphalt production as much as 15 and 25 C respectively in application of 10 resin It is alsoconcluded that the steel slag warm mix asphalt has a better performance than warm mix asphalt in the caseof mechanical properties Both SSWMA and WMA had acceptable moisture resistance but the moistureresistance of steel slag warm mix asphalt is much higher than that of warm mix asphalt Keywords Warm mix asphalt Steel Slag Amino Based resin Energy consumption
