AbstractThe main purpose of the project is to convert polyethylenetetraphylate (PET), a known plastic
waste material in Ghana, to wealth. Composite samples were produced by heating aggregates
together with shredded PET plastic waste material, while bitumen was added to the plasticcoated aggregates. The composites produced were of 4.5 wt%, 9.0 wt%, 13.6 wt% and 18.0
wt% concentrations of PET. Mechanical and optical characterisation of the fabricated
composite samples were studied for optimization. Moreover, corrosive studies via mass loss
and thermal degradation studies were performed on the test samples. From the statistical
analysis conducted, it was demonstrated that shredded PET plastic waste material acts as a
strong binding agent for bitumen making the asphalt last longer. From the results, 13.6 wt%
concentration of PET was shown to have the maximum compressive strength. In addition,
water resistance was shown to increase with increasing PET concentration of 4.5 wt%, 9.0
wt%, 13.6 wt% and 18.0 wt. The optical characterisation results revealed that the samples with
13.6 wt% PET plastic concentration had lesser voids, lesser discontinuities and maximum
bonding strength. From the data analysed, 13.6 wt% PET plastic gives the optimum plastic
concentration that enhances the rheological properties of bitumen. The implications of the
result are therefore discussed for the used of 13.6 wt% PET in road construction
