Modified asphalt binders offer better mechanical performance in field conditions. According to many researchers, nanoclay modified asphalt binders can be a cheaper alternative of currently practiced polymer modified binders. The primary purpose of this study was to observe any changes in asphalt chemistries due to nanoclay modification and explore any correlations that may exist between chemical compositions and mechanical properties. Changes in chemical fractions were found to be source variant. Insoluble Asphaltene contents were observed to increase significantly after aging, whereas the Saturate contents decreased. Correlations were observed between mechanistic properties and chemical compositions. Moreover, aggregate-binder compatibility evaluation showed nanoclay modified binders offered better bonding with gravel than sandstone. Acidity measurement was helpful only to trace any presence of acid and the extent of modification. Furthermore, Fourier transformation infra-red spectroscopic analysis (FTIR) depicted changes in certain functional groups due to modification and aging.
