Due to various properties and advantages, bitumen is used in road construction and gains certain unique properties. The research involved the modification of bitumen characterizing the results with diverse techniques, such as thin layer chromatography or Fourier transform infrared spectroscopy. Conclusions involved that rheological properties of foamed bitumen are improved and the degree of enhancement is dependent on bitumen characteristics. Bitumen is produced by partial distillation of crude petroleum. it is chemically a hydrocarbon and insoluble in water.
