COMPOSITION AND PHYSICO-MECHANICAL PROPERTIES OF BITUMEN

CONSTITUTION ET PROPRIETES PHYSICO-MECANIQUES DES BITUMES

Following details of the manufacture of bitumen used in road construction from the distillation of petroleum, a study is presented of the composition of bitumen: asphaltene, malthene (resin, ore), carboid and carbene, and of molecular masses (comprised between 600 and 1200). Separation methods are reviewed: by means of solvents, chromatography, and other techniques. Analytical methods are described; the physico-mechanical properties of bitumen are investigated from the rheological point of view: standard empirical tests, ductility and adhesion. The relation between composition and properties of bitumen is studied together with the evolution of bitumen in time by means of ageing tests and direct and indirect laboratory simulated ageing test methods. The evolution on bitumen on actual road is also investigated. The covering abstract of the conference is IRRD abstract no. 101124. /TRRL/
