Abstract: Environmental solid wastes increase more and more as a result of the
industrial waste production day by day. Management of the solid wastes is the
thrust area for researchers. In this study, the effects of asphalt plant residue
(APR) on the properties of hot mix asphalt (HMA)s are investigated. APR was
added into the asphalt concrete in 25, 50 and 100% by weight of the filler. In
order to determine optimum bitumen content, Marshall Design procedure was
applied. Optimum bitumen content (OBC) values were obtained less than
control specimen (CS). APR specimens have shown little increase in Marshall
stability and little decrease in flow except for APR-50 in comparison to the CS.
All APR specimens have higher MQ than that of the control mixture. Although
there are no meaningful differences between CS and APR specimens, APR can
be used as a filler aggregate in asphalt mixtures. Use of APR will enable
recycling of an environmental waste as well as providing some benefits in
asphalt concrete performance. Thus, resources will be used more effectively all
over the world as part of sustainability.
