Microstructural Changes in Bitumen at the onset of Damage-healing

, 2016
Self-healing of bitumen is a property that positively contributes to the sustainability, maintenance requirements and cost effectiveness of asphalt pavements. Ideally one would like to design an asphalt mix with a well-defined healing potential. Although

The influence of bitumen on reservoir quality of a siliciclastic deposit: application to the Salam field (Western Desert, Egypt)

, 1998
Bitumen are rarely taken into account in the petrophysical characterization of reservoirs because they may be rather difficult to distinguish. This paper focuses on the effects of bitumen on the reservoir quality of the sandstones from the Salam Field in
