Chemical
Recycling of Polyethylene Terephthalate (PET) as Additive for
Asphalt |
|
Utilization
of waste material in asphalt pavement
would be beneficial in order to find an
alternative solution to increase
service life of asphalt pavement and reduce
environmental pollution as well. One of these
waste materials is
plastic water bottles (Polyethylene
Terephthalate) (PET) which are being
produced in large amount. In this research
Polyethylene Terephthalate (PET) was used to
investigate the possibility of using
waste plastic bottles made of
Polyethylene Terephthalate (PET) as
additives in bituminous mixture to
overcome the pavement problems. Six different proportions
(w/w %) of (PET) in (2, 4, 6, 8, 10, and12)
has been added to bitumen to prepare
the specimens. The tests include
examination of Fourier Transform Infrared Spectroscopy
analysis (FTIR) before and after PET chemical
recycling, then ductility and
penetration for bituminous. The
results showed that the modification
has increased by increasing the content of
(PET %). This addition gives maximum
flexibility and rigidity of the
asphalt according to ductility increasing and penetration
decreasing, by
comparison with non-modified mixtures and give
better resistance against permanent
deformations and better engineering
properties. |
