Use of Plastic Waste (Poly-ethylene Terephthalate) in Asphalt Concrete Mixture as Aggregate Replacement

An environmental program in most regions of Iran is the large number of bottles made from poly-ethylene terephthalate (PET) deposited in domestic wastes and landfills. This article reports on an experimental study undertaken to investigate the possibility of using PET waste in asphalt concrete mixes as aggregate replacement (Plastiphalt). In the study, the mechanical properties of Plastiphalt mixes were compared with control samples, focusing on the parameters of Marshall stability, flow, Marshall quotient (stability-to-flow ratio) and density. The waste PET used in this study was in the form of granules of about 3 mm diameter which would replace (by volume) a portion of the mineral coarse aggregates of an equal size (2.36-4.75 mm). The results showed that the aggregate replacement of 20% by volume with PET granules would result in a reduction of 2.8% in bulk compacted mix density. The value of flow in the plastiphalt mix was lower than that of the control samples. The results also showed that when PET was used as partial aggregate replacement, the corresponding Marshall stability and Marshall quotient were almost the same as for the control samples. The authors conclude that the use of PET in this asphalt mix is suitable for practical use and that the recycling of PET for asphalt concrete roads helps alleviate a difficult environmental problem.
