This study aims at investigating the impact of recycling by-product plasterboard wastes (gypsum and bassanite) with asphalt mixtures by replacing partly the filler portion of the asphalt mixtures with pulverised plasterboard wastes in order to contribute to non-toxic and good urban environment on one hand and improve, or at least retain, the design mechanical properties of the resulting asphalt concrete mixture on the other. The study was based on series of wheel tracking tests which successfully proved the possibility of mixing recycled plasterboard wastes with asphalt mixtures. The tests results showed that asphalt samples of 40% gypsum-filler ratio and asphalt samples of 40% bassanite-filler ratio as well gave the maximum resistance to plastic deformations and hence maximum dynamic stabilities. As a result, this research has shown that mixing of plasterboard wastes with asphalt concrete mixtures in specific quantities is promising.
