Investigating the Effects of Using Waste Rubber and Polyethylene Terephthalate (PET) on Mechanical Properties of Asphalt Concrete
H. Taherkhani and M. Reza Arshadi
Abstract—Scrap tires and plastics are among the main solid
wastes generated in large amount throughout the world.
Polyethylene Terephthalate (PET) is the most consumed and
wasted plastic. In this study the effects of PET particles size and
content on some engineering properties of asphalt concrete
containing rubber modified asphalt has been investigated.
Different concentrations of waste PET including, 0, 2, 4, 6, 8 and
10% (by the weight of binder) in two different ranges of size
were to asphalt concrete and the Marshall stability, Marshall
quotient, indirect tensile strength (ITS) and uniaxial dynamic
creep properties were evaluated. Results show that the Marshall
stability and Marshall quotient increase with increasing PET
content. The indirect tensile strength (ITS) test results show that
the highest ITS is obtained by adding 2% of PET into the
mixtures and beyond that the ITS decreases with increasing
PET content. Dynamic creep test results revealed that the
resistance against permanent deformation decreases with
increasing PET content. However, the mixture containing fine
graded PET particles has more resistance against permanent
deformation than the mixture containing coarse graded PET
particles. Comparing the results on the rubber modified
mixtures in this research with those on conventional mixtures
accomplished previously reveals that the trend is different.
