Stability of Bituminous Emulsion Induced by Waste Based Bio-Surfactant

In the asphalt industry, bituminous emulsions are widely used in road pavement operations and building/construction processes such as cold mix waterproofing processes, respectively. A very important fact to keep mind is that not all types of bitumen suitable for realization emulsions. This largely due variation their chemical nature different cracking carried out on during fractional distillation process petroleum industry. The objective this study identify underlying causes non-emulsionability using Nuclear Magnetic Resonance (NMR) Dynamic Shear Rheology (DSR) analysis. NMR analysis aims at identifying fundamental components responsible emulsionability binder how role phenomenon. On other hand, DSR aimed determining if rheological (viscoelastic) behavior implicated its emulsionability. indications gotten from data produced by these techniques, enable us soon analyzed deemed non-emulsionable what type additive can be modify alleviate until a point where become ideal research work, model (labelled Cimar) which known excellently high production anionic was reference sample. Two bitumens Adriatica Alma) preliminary testing were alongside additives selected subjected aforementioned techniques obtained allowed identification design right improves makes it preparation addition these, uncommon however effective method acid number determination gave an factor influences bitumen.
