| Abstract | ||
| The influence of natural rubber along-side with chlorine gas on the bitumen blends characteristics have inspected. The modification performed through passing chlorine gas on molten bitumen mix prepared using bitumen and rubber latex of variety percentages. Penetration, penetration index, ductility and softening point have tested. In addition, viscoelasticity, rutting resistance and thermal stability have measured using dynamic shear rheometric analysis and differential scanning calorimetry, respectively. The chlorination has confirmed via Fourier-transform infrared spectroscopy analysis and asphaltene ratio determination. The acquired data showed an improvement in the thermal stability besides obvious enhancements in the viscoelasticity and rutting performance of the resulted blends. The results give clear advantage, for potential usage of such blends in the road paving application. © 2020 NIODC. All rights reserved | ||
