In this paper, we examine the simultaneous effect of polyethylene terephthalate and silica fume on the rheological and mechanical properties of concrete pavements and looking to present a new mix of green concrete (environmentally friendly concrete) with the use of PET waste materials and silica fume. Due to problems with asphalt pavement, such as endangering the environment, bitumen is expensive and considering that Iran is currently the third-largest producer of cement worldwide. Therefore, concrete pavements have been given special attention today. It also increases the consumption of pet food bottles and, consequently, increases waste production, and increasing the waste disposal site adds to the importance of reuse of these wastes. One of the uses of these lesions, without having a destructive effect on the environment, reusing them is to enclose them in concrete rigid pavements. On the other hand, research shows that another piece of waste products in the glass industry which is known as micro silica or silica fume which can be used in concrete pavement. The results from this study indicate the use of pet particles in concrete pavement did not have much impact on compressive strength But in contrast, it increases the tensile strength, bending. In contrast to the use of micro silica, it has increased compressive strength, reduced water absorption, and reduced permeability in concrete pavements.
