Abstract

This study investigated the influence of Cow Dung Ash (CDA) and Polyethylene Terephthalate (PET) as partial replacement of filler and binder respectively on the volumetric and Marshall Properties of asphalt concrete in separate mixes. In one mix, the filler was partially replaced with CDA at 4, 8, 12, 16 and 20% while for the other mix, the bitumen was partially replaced with PET at 3, 6, 9, 12 and 15 %. Asphalt briquettes were produced in accordance with marshal procedure for wearing course of medium traffic roads and marshal stability, while properties of the mixes were obtained from the flow and volumetric parameters. Results showed that replacing the filler between 4% and 8% with CDA has the potential for use in asphalt concrete. Also, for mixes with PET replacement, percentages between 6 and 15% can be considered for wearing course of medium trafficked roads.
