Waste Polyvinyl Chloride (PVC), a non-degradable material used for engineering works with other relevance importance in developmental effect rather than its negative environmental impact. The addition of synthetic polymer to enhance properties of bitumen over a wide-range of temperatures hip road paving application been considered long time ago and consequently becoming real alternative for pavement extended life. This work is focused on the effect of polyvinyl chloride (PVC) modified bitumen in hot mix asphalt (HMA). Marshal method of mix design was used in the production of hot mix asphalt. Scanning Electron Microscopy (SEM), Fourier Transform Infra-red (FTIR) and Energy Dispersive X-Ray Spectrometry (EDS) used for microstructural investigation and elemental study. The percent PVC content incorporated in the HMA were 2, 4, 6, 8, 10% PVC content, the OBC obtained 10%, at 10.75kN for the Modified and 4% at 9.8kN for Control. The modified materials with its properties shows, penetration recorded at 65mm, which conformed with, 60/70 grade bitumen, softening point recorded at 53oC.
