چکیده
Three samples of bituminous material with different softening temperatures 321, 332, and 356.4 K were obtained by the method chemical modification tar formaldehyde using sulfuric acid as a catalyst. The determination group hydrocarbon composition was carried out for raw materials process (tar) resulting bitumens. An FTIR study groups hydrocarbons (oil, resins, asphaltenes) also out. structural transfor¬mations investigated possible chemistry proposed.
