| description | The present study deals with the effect of saw dust ash (SDA) as an alternative filler and recycled asphalt pavement (RAP) material in bituminous concrete (BC). Several physical and chemical experiments were performed to characterize the SDA and RAP material according to the standard specifications. To execute such study, virgin aggregate and RAP were blended as 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 25 :75, 0 :100% and 8% SDA was used as filler to prepare the BC mix. In this study, 2% ordinary Portland cement (OPC-43) was utilized to prepare the control mix. However, to quantify the performance of RAP and 8% SDA in the BC mix, several Marshall properties, and the performances criterion against various distress (rutting, cracking, and moisture susceptibility) were conducted. The experimental results reveal that 60% RAP-8%SDA enriched BC mix shows superior rutting, cracking, and moisture resistance potency with the highest structural integrity of 82.10%. Since the dominant percent of calcium oxide mineral present in that filler reacts with the dipolar carboxylic acid which already exists in an aged binder and thus the adhesive property of the binder in the BC is improved significantly. |
