Guliak D. Technological and operating ageing of tar-macadam mixtures and tar-macadams and methods of their ageing process deceleration

The thesis is devoted to the theoretical and experimental establishment of physi-cal and chemical regularity of ageing processes of tar-macadam mixtures and tar-macadam's in the manufacture process, thermostatting in thermos bunker, the transportation to the site of placement in the pavement construction, being in operation conditions, and the development of deceleration methods of ageing processes, and durability increases of roadway tar-macadam coverings. Worked out methods of tar-macadam mixtures ageing deceleration, i.e., by modification of coal binder with wastes of polyvinylchloride production, complex addition (primary sitting of polyvinylchloride in combination with active dispersible filer-still residue of phtalic anhydride distillation); by the complex modification of tar-macadam microstructure (mechanical activation of mineral powder with oligomers, and the coal tar - by the polyvinylchloride sifting).
