The effect of the addition of clay as a third component in polymer modified asphalts has been investigated. After a preliminary investigation on the binary asphalt/clay and polymer/clay blends, the tertiary blends were prepared by adding the clay and polymer to the asphalt, either separately or in the form of a premixed master batch. Intercalated nanocomposites with comparable interlayer distances and glass transition temperatures were obtained in both cases. However, the results show that the mixing procedure significantly affected the final rheological properties. The master curves built in the linear viscoelastic range and represented in both the frequency and the temperature domains help to visualize and evaluate such differences. Suggested Reviewers:Dear Professor Vancso, I'm submitting the new version, revised according to referees' suggestions. I would like to thank you and the referees for helping us in improving the quality of the paper.

“…This effect makes polymer molecular chain smoother and greater in volume. This is so called swelling effect (Polacco G, 2006). When SBS particles disperse in asphalt, swelling happens and polymers absorb light oils in asphalt.…”

“…In addition to, compatibility depends on chemical composition of asphalt base, type of polymer and process of mixing. Blend will be considered compatible if the polymer is completely soluble in bitumen [31].Unification during storage period of blend is compatibility of mix [32]. Study found that compatibility of polymer modified bitumen is influenced by temperature and thermal properties of blend [33].A large number of polymers are not soluble in bitumen at some extent, separation occurs due to lose bonding between them [31].…”

ABSTRACT:This study examines properties of waste plastic water bottles, polyethylene terephthalate (PET). The waste polymer was added to the normal bitumen penetration grade (80/100) prepared Marshall Samples using ACW-14 to investigate Marshall Parameters of polymer modified bitumen and compare with conventional bitumen. Thermal analysis of PET waste polymer was carried out using TGA and DSC to study decomposition and melting temperature of the waste polymer and also select suitable type of polymer because compatibility of the material is an essential. Basic penetration, softening point, ductility test was performed and study finding shows that penetration and ductility decrease while softening point increase by addition of polymers. Marshall analysis of the study found that by addition of 9% polymers to the bitumen by weight of 5.5% at optimum level increase Marshall properties and give all positive response for polymers PET such as stability increase up to 60-70%, stiffness, flow, density and voids of the polymer modified bitumen found positively improving and enhancement was observed compared to conventional, which is the key objective of this study. In conclusion the polymers modified bitumen improves stability, workability and reduce deformation in road pavement.
