The aim of this study was to evaluate the effect of recycled polyethylene on physical and rheological properties of polymer modified bitumen. Four type of analysis consist of rheological, mechanical, thermal and surface morphology was conducted to study the effect of polyethylene content on bitumen binder. Dynamic shear rheometer was used to study the rheological properties of the composite binder. Thermogravimetric studies showed that the thermal stability of polyethylene modified binder was improved compared to unmodified binder. Gradually increase in the polymer contents has increased the complex shear modulus, storage modulus and loss modulus of the bitumen binder.
