Chemical fractionation of nickel in asphaltite based bottom ash

open access: yes, 2013
Asphaltite, originating from petroleum, contains many kinds of mineral elements derived from its generation. These elements exist in different forms which may change throughout the asphaltite combustion process.

Modeling the linear viscoelastic behavior of asphaltite-modified bitumens

open access: yes, 2016
International audienceA modeling approach which allows predicting the linear viscoelastic behavior of bitumen blends from the linear viscoelastic properties of individual constituents is presented in this paper. This approach consists in a combination of
