Influence of Shredded Waste Water Sachet on Engineering Properties of Asphalt

Olukorede M. Osuolale, Kehinde S. Agbalaya


The search for any improvement has always brings about some sort of modification especially if a new discoveryhas not been made. This research work focused on the potential utilization of waste water sachets in themodification of the engineering properties of asphalt cement (Bitumen) used in the production of Asphalticconcrete.In achieving this, the samples of waste water sachets were collected from four sachet water producing companiesin Ilorin. They were sun dried and later shredded. The bitumen was replaced by shredded waste water sachets byweight at 1 to 10%. Some conventional Laboratory tests were carried out on the unmodified and modifiedbitumen specimens.The property of bitumen was strongly affected by the addition of shredded water sachet. The specifications ofAmerican Society for Testing and Materials {ASTM} and Government of Federal Republic of Nigeria GeneralSpecifications for Roads and Bridges were employed as guides. A modification of 1 – 3 % could be allowed asalmost all requirements are met except the Softening Point of 3 % modification that seems to be on the high side.The modification enhances the resistance to permanent deformation, fatigue cracking and cohesion. Furtherstudy of the research is encouraged and could involve asphalt concrete production from the modified asphaltcement to investigate the effects.Keywords: Waste water sachets, Bitumen, Modification, Engineering properties.
