Utilization of Waste Asphalt as an Additive in Mortars

Celik Sola Ozlem and Ozyazgan Cemil
Abstract—In this study waste asphalt was used in cement production to progress different types of civil engineering materials. For this purpose waste asphalt in three particle sizes was collected from Turkey were added to the Portland Cement (PC) and blended cement mixtures were prepared. After the chemical analysis and some physical properties of the cement mixtures (density, blaine, setting time), cements were produced by adding waste asphalt to PC. Waste asphalt was added to PC in ratios of 10% and 15% (wt/wt) respectively. The mortars produced with different groups were tested for compressive strength values on 98 days according to European Standard (TS EN 196-1). The curing conditions were water, freeze-thaw and wet-dry. The results showed that mortars with waste asphalt had much higher compressive strength values than reference cement mortar for Y. In addition to these results, when particle size decreases, compressive strength increases in mortars with waste asphalt. After determining compressive strength results, XRD and SEM analysis were taken from No#1, No#4 and No#7 due to the highest compressive strength results. The SEM analysis showed that the improvement in compressive strength by the waste asphalt was a physical effect.

Index Terms—Cement, SEM, waste asphalt, XRD.
