Iron-polyphenol complex nanoparticles for removal of greenhouse gas emission from bitumen and formation of paraffins.

The removal of greenhouse gas (GHG) emission from bitumen used in the construction of flexible pavement by iron-polyphenol complex nanoparticles (Fe-PNP) has been examined in the study. Laboratory studies indicated the removal of carbon dioxide (CO) with Fe-PNP is a function of the amount of additive (Fe-PNP). From the experimental data, it was found that the reduction of CO increases with increasing amount of additive up to a dosage of 4% (by weight of bitumen) without severely changing the basic engineering properties of the bitumen.
