Study on Rheological Properties of SBS Modified Asphalt with PET Content
In this study,recycled plastic polyethylene terephthalate(PET)and styrene-butadiene-styrene(SBS)were used to modify as-phalt.The rheological properties of modified asphalt binder(PS-MB)were studied by conventional binder tests(permeability,softening point,viscosity and storage stability tests)and rheological tests at high and low temperatures.The results show that the rheological properties of SBS modified asphalt can be effectively improved by using PET as the modifier.
