Abstract: 
Хімічним модифікуванням гудрону формальдегідом з використанням як каталізатора сульфатної кислоти отримано три зразки бітумного матеріалу з різними температурами розм’якшення 321, 332 і 356,4 К. Визначено груповий вуглеводневий склад сировини процесу модифікації (гудрону) та отриманих бітумів. Також здійснено FTIR-дослідження одержаних груп вуглеводнів (олив, смол та асфальтенів). Досліджено структурні перетворення та запропоновано можливий хімізм процесу модифікування гудрону формальдегідом.
