CONTRIBUTION TO THE STUDY OF THE CATIONIC INTERFACIAL ACTIVITY OF ROAD BITUMENS

CONTRIBUTION A L'ETUDE DE LA TENSIO-ACTIVITE CATIONIQUE DES BITUMES ROUTIERS

The first part of this report presents general data on the use of bitumens in road construction, their manufacture, their physico-chemical characteristics and their structure. The influence of interfacial properties on the coating of solid materials and on the properties of composite materials where they are used as binders. Part 2 shows the role played by acid and basic compounds on interfacial properties such as interfacial tension vis-a-vis aqueous phases and the wetting of solids. These polar compounds show an anionic and cationic interfacial behaviour. A comparison is made between the behaviour of polar compounds extracted from bitumen as nitrogen bases and that of surface-active agents used as adhesion agents. Part 3 deals with cationic interfacial activities. A comparison is made of five bitumens and two reference amines: n-dodecylamine and cyclododecylamine. Their interfacial activity was shown to be the same as that of cyclododecylamine. But it is not possible to completely simulate the behaviour of a bitumen by that of an amine of this type: indeed it seems that non-interfacial active compounds in bitumen can modify the interfacial absorption conditions of the cationic surface-active agent. /TRRL/
