ABSTRACT
Microcalorimetry (DSC) is a simple, quick technique of preparation as well as getting results. Verification work shown along this article allowed to verify the validity of the data published after more than 25 years of explorations of the field of bitumens and polymer modified bitumen through the use of this tool. Interest is evident with respect to the identification, the presence and assaying the crystallizable phases in bitumens: organized fractions, group in which the paraffins are located.

KEYWORDS
differential scanning calorimetry, bitumen, modified bitumens, polymers, paraffin.
