The effect of melt mixing conditions on the thermal and morphologicalproperties of bitumen / polyethylene terephthalate / clay nanocomposites

In this research, bitumen-polyethylene terephthalate (PET)-clay nanocomposite was made by meltmixing method. The amounts of PET in ۵ wt.% and nanoclay in ۲ wt.% were fixed for all samples.The effect of different mixing conditions, including the mixing sequence, mixing time and mixingtemperature, was considered. The results of the FTIR showed good interaction between bitumen andclay. The TGA indicated that increase in mixing time and temperature led to better thermal behavoir.TEM observation showed intercalation and partially exfoliation morphology of caly in bitumen/PETmatrix.
