THE INFLUENCES OF ALTERING THE MIXING CONDITIONS ON THE PROPERTIES OF POLYMER MODIFIED BITUMEN: AN OVERVIEW

Abstract

Modification of bitumen by different modifiers, causes the morphological, rheological and chemical characterisation differences related to the following three main factors: the type of the polymer, bitumen components and blending conditions. Manufacturing conditions can be investigated in several groups such as; mixing temperature, duration of mixing and shear rate (mixing speed). These manufacturing conditions are the key parameters, since they act an important role on the properties of the final product. These key parameters and their effects have always been an interesting topic for the researchers, because they may have some consequences like aging of the sample, degradation of the polymer or sometimes less absorption of the polymer by bitumen etc. This study aims to present the influences of mixing conditions on different properties of the bituminous mixtures with the help of reviewing the previous studies in the literature.
