Studiul proprietăților reologice a bitumului

Abstract

The rheological properties of bitumen are transmitted building materials based on bitumen, with some modifications and attenuation introduced by other components of these materials. Rheology can be regarded as a branch of physics that deals with the behavior of deformable bodies that possess at least one of the following properties: elasticity, plasticity and viscosity. Rheology of bitumen at a given temperature is determined both by the constitution, ie its chemical composition and physical arrangement of hydrocarbon molecular structures predominate in the material. A change in the constitution or only physical structure, or both of them, leading to bitumen rheology modification. Thus, to understand the changes occurring bitumen rheology-structure interaction is essential to know the constitution in influencing rheology.
