Chemical change of the asphalt properties by water effect
Ana Sofia Figueroa Infante
La Salle University, Colombia
This research studies the effect of water on the AC 80-100 asphalt. The bitumen was evaluated under the action of water
and its rheology was assessed through tests with the dynamic shear rheometer. Physical performance was evaluated by
conventional empirical tests that included penetration, softening point, ductility and viscosity. The chemical tests were evaluated
on liquid chromatography (fractionation SARA) and infrared spectroscopy. The results showed that water has a significant
influence on the physical, visco-elastic and chemical properties of asphalt. Rheological properties showed a sinusoidal value of
|G*| also changes the asphalt δ angle exposed to water. Chemical properties showed important changes in the activation energy
of asphalt and consequently emerged some functional groups that are evidence of asphalt aging such as sulfoxides and carboxiles.
