SANABRIA, Luis E.; CHIMAN, Larissa  and  CHIMAN, Alexei. INFLUENCE OF HEAVY PARAFFINS ON CERTAIN ASPHALTIC PROPERTIES. C.T.F Cienc. Tecnol. Futuro [online]. 2002, vol.2, n.3, pp.113-120. ISSN 0122-5383.

The influence that saturated compound fractions -and, specifically, heavy paraffins- have on the chemical composition of asphalts and their asphaltic properties was assessed through the use of a complex asphalt produced in Barrancabermeja (CIB). Phenomena caused by the aforementioned substances on ductility, penetration, softening point, rheological curve, humidity susceptibility (TSR), and deformation resistance (DSR) of CIB asphalt were identified. The identified effects were explained in light of the changes in the asphalt's colloidal system.

Keywords : Heavy paraffins; effects on asphalt.
