Abstract: Amidoamines have been synthesized on the basis (in molar ratios of 1:1-6:1) of synthetic petroleum acids and polyethylene polyamines obtained from the aerobic oxidation, in the catalytic presence of salts of transition metals in liquid phase, of naphtene-paraffin hydrocarbons of the Azerbaijan petroleums mixture separated from diesel fraction. The compositions of synthesized acids mixture in various percentage ratios (95-15%) with AK-15 motor oil have been prepared. The physical and chemical indicators of prepared compositions have been studied. These compositions have been used as a high-quality additive for road bitumen in purpose of enhancing the quality indicators of road bitumen. The compositions prepared on this purpose have been added to bitumen in amount of 0.4% and 0.6%, and the quality indicators have been compared with the quality indicators of the road bitumen produced at the Baku Oil Refinery named after H.Aliyev. It has been defined that an adhesion varies from 3 to 1 point by adding these compositions in small amount to bitumen. According to the quality indicators of bitumen, it can be mentioned that when the compositions of 0.4% prepared in concentration of 5÷15% on the bases of amidoamine, obtained from taking in molar ratio synthetic petroleum acids: polyethylene polyamines=5:1, and AK-15 motor oil added to bitumen at 25°C the values of penetration of 49-51 mm, extensibility up to >100 cm, brittleness temperature at interval of minus 22-27°C are obtained. It is defined that more positive results with enhancing the quality indicators significantly, are achieved in case of adding the composition of 0.6% obtained by taking amidoamine (90%) synthesized in molar ratios of synthetic petroleum acids: polyethylene polyamines=5:1 and AK-15 motor oil (10%) to the road bitumen
