STUDY OF THE MECHANISMS OF ADHESION AND STRIPPING OF ROAD BITUMEN

ETUDE DES MECANISMES D'ADHESION ET DE DESINROBAGE DES BITUMES ROUTIERS

The authors describe the research carried out on the chemical aspect of adhesion. They show the existence of reactive chemical activity at the bitumen/water/aggregate interface. This activity depends naturally on the nature of each of the bodies involved and also on the conditions in which contact occurs, e.g. conditions of adsorption. The segregation of the bitumen ingredients adsorbed on the aggregate and the analysis of its effect on interfacial tension together with the study of water/aggregate interactions lead to the definition of a stripping process which is observed by means of electrical conductivity, then by means of a chemical mechanism of stripping in which dope is taken into consideration.
