STUDY OF BREAKING MECHANISMS AND COHESION BUILD-UP ON BITUMINOUS EMULSIONS

Preliminary studies have shown that the build-up of cohesion is not due to the progress of coalescence only but that it is also strongly dependent on the rheological properties of the binder. A specific part of the study will thus be devoted to the measurement of these rheological properties. The breaking and coalescence process will be studied through in-situ observation techniques such as optical and electronic microscopy. These direct observations will be combined with methods allowing quantifying the stability of interfacial films, such as centrifugation, dialysis and the measurement of contact angles. The purpose of this task is to identify and understand the mechanisms, which control the breaking and cohesion build-up phenomena. In particular, it will be attempted to develop adequate test methodologies. It will then become possible to investigate the impact of various factors such as binder viscosity and physic-chemical emulsion properties. For the covering abstract see ITRD E107185.
