Abstract
Extracted asphalt from the sulphate asphalt springs in Heet area was
prepared to study its properties and its also involve the study of UV and IR
spectra of the natural samples and compared to the spectra of similar
petroleum samples taken from Al-DORA Refinery .The study shows that the
properties of natural asphalt have a great similitude with the asphalt samples
resulting from refining Iraqi petroleum. Analysis of UV and IR for the
asphalt sample show the existence of heavy organic compounds, that’s found
in asphalt extracted from refineries that used for building and construction
and for road pavements.
