In this article, the flow type of two different asphalt-plastic blends has been determined. One of these blends was prepared from the mixture of asphalt-cement that has a penetration degree of 60-70 (AC60-70) and low-density polyethylene (LDPE), and the other was prepared from the mixture of asphalt-cement that has a penetration degree of 150-200 (AC150-200) and low-density polyethylene (LDPE). Also, a model of the variation of the blend viscosity with temperature and concentration has been developed. It was found that this model is in a good agreement with the experimental data obtained and the relative error is calculated as 10-15%.
