description: The theme of the final qualification work: Â«Economic effect and rationale for the use of stabilizing additives for the preparation of asphalt mixtures in the conditions of the street and road network of St. PetersburgÂ». This work is devoted to the study of the influence of the amount of stabilizing additive on the quality of the asphalt mix, as well as the study of the economic efficiency of the use of crushed stone mastic asphalt in road construction. In the course of work, you must perform the following tasks: To analyze the information about modern stabilizing additives; To analyze the experience of using modern stabilizing additives in road construction; To analyze the effect of stabilizing additives on the physical, mechanical and operational properties of stone mastic asphalt; Evaluate the effect of various percentages of stabilizing additives on the physical, mechanical and operational properties of stone mastic asphalt; Determine the economic efficiency of the use of stone mastic asphalt in the conditions of the street and road network of St. Petersburg; Justify the use of stone mastic asphalt in road construction. The theme was developed by order of PETERSBURG-DORSERVIS JSC. The experiment was carried out in a laboratory at the Higher School of Industrial, Civil and Road Construction. In this work, an analysis of the available modern data on stone mastic asphalt mixture and stabilizing additives was carried out. During the experiment, a relationship was established between the percentage of the stabilizing additive and the draindown index. In the work, cost calculations were carried out to determine the economic efficiency of using stone mastic asphalt. As a result, the influence of the amount of stabilizing additive on the quality of the finished asphalt concrete mixture was established, the estimated cost of the current repair of the top layer of the road surface for different types of asphalt concrete mixtures at current prices and adjusted for inflation was determined, and the use of stone mastic asphalt in the conditions of the road network of St. Petersburg was justified.
