Abstract:
The management of the waste materials produced on the earth is one of
the highly substantial environmental issues. Hence, the increasing usage of plastic
every year is one of the concerns across the entirety of theworld. The limiting landfill
conditions and higher production of the waste plastic materials stress the researcher
to manage it alternatively. Conversely, the growing number of heavy vehicles on
roads cause road distress to asphalt pavements that contain pure asphalt binders that
are insufficiently resistant. Civil engineers and scientists have attempted to address
such issues by enhancing the performance of asphalt pavement via modification of
asphalt binders’ properties. This paper summarized the possible utilization of waste
polyethene terephthalate (PET) for binder modification. It has been evaluated that
the PET can significantly improve the binder properties. The chemical modified
PET showed better performance in term of physical and rheological properties. In
addition, the compatibility of PET with binder has been highlighted with modified
chemical structures and viamorphological assessment of modified binder. In addition
to solving landfilling issues of waste PET plastic, such recycling approaches generated
in these studies can also be used by asphalt researchers to explore future avenues
of improvement for the characterization of asphalt binder as a paving material.
