An experimental-statistical model has been developed and optimal conditions for the modification process have been established. The chemistry of chemical modification of oil residues with formaldehyde has been studied. The environmental friendliness of the proposed technology has been proved. A complete physico-mechanical analysis of bitumen samples obtained by modification of tars with formaldehyde, as well as formation and testing of crushed-mastic asphalt concrete using this bitumen were performed.   Product Description popup.authors Hrynchuk Yurii M Gunka Volodymyr M Demchuk Yuriy Ya Prysiazhnyi Yurii V Sidun Iurii V popup.nrat_date 2021-09-02 Close
