“…For research conduction to prepare the modified bitumen and the polymer asphalt concrete there were used the stone materials from the Malynsky enterprise and the mineral powdered lime, the petroleum paving bitumen of 60/90 grade from the Mozyrsky enterprise, and the Butanol NS 198 modifier. The components quantity determination results showed their compliance with the asphalt concrete functional standard [11]. To obtain the uniform asphalt concrete samples and to ensure the same specific surface of the mineral components the stone material previously was dispersed on the standard fractions.…”

For research conduction to prepare the modified bitumen and the polymer asphalt concrete there were used the stone materials from the Malynsky enterprise and the mineral powdered lime, the petroleum paving bitumen of 60/90 grade from the Mozyrsky enterprise, and the Butanol NS 198 modifier. Conducted research showed that the asphalt concretes produced using the Butonal NS 198 meet the requirements to hot asphalt concrete and have higher strength and durability parameters. The polymer asphalt concrete design characteristics values change in sufficiently wide range depending on the binding agent amount shows the possibility of active regulation of its properties under the designing actual conditions. Higher water resistance and extended durability of these PACs ensure the preconditions of their use in different regions of Ukraine. Research results show that to get the maximum effect from the modifying agent application it is desirable to perform the scientist support during its field use and also the operational conditions monitoring to collect statistic data and carry out the necessary corrections to obtain the best results.

“…The objective of the "Rehabilitation of the Volga" project is to reduce the volume of wastewater discharged into the Volga by three times from 3.2 km3 to 1.1 km3. In addition, it is planned to begin the restoration of the banks, as well as to raise 95 vessels from the bottom, which harm the water area of the river [4][5][6][7][8][9][10].…”

Recycling of household waste and environmental pollution is currently one of the most serious environmental problems in Russia. During the year, about 400 kg of household solid waste is generated per inhabitant of Russia, and effective methods of inorganic waste disposal have not yet been developed. Human wastes also have a significant impact on the pollution of water bodies, since water used in cities for sewage system needs often goes directly to open water bodies, bypassing a system of treatment facilities that have poor quality: most of them are already almost unable to cope with their functions due to outdated and unusable equipment. The subject of the study is the national project “Ecology” developed in Russia. The purpose of the study is to create a set of additional measures to improve the environmental situation and reduce the emissions of pollutants into the atmosphere. To study the topic, the trends of the environment change and the scenario of the expected trends up to 2030 have been systematized. Reduction of expenditures on the national project “Ecology”. This project is mainly aimed at combating the effects of environmental pollution, rather than identifying the causes of degradation processes.

“…Fourier spectra are widely used in engineering seismology and serve as the main means for assessing the spectral composition of recorded ground movement or the reaction of structures, but other functions are determined using Fourier spectra, such as power spectral density functions, transfer functions, and coherence functions. [11] To construct the response spectra, it is necessary to solve the differential equation:…”

“…For example, vibrations propagating during the movement of railway trains contain harmonics up to 100 Hz. [ 9,10,11] The spectra of maximum velocities and spectra of maximum accelerations can be obtained in the same way as the spectra of maximum displacements were determined. The difference will be that instead of defining peak displacement values, it will be necessary to determine peak velocity values and peak acceleration values.…”

“…It has a number of properties that are convenient to use in solving dynamic problems and for describing seismic effects. Fourier spectra are widely used in engineering seismology and serve as the main means of assessing the spectral composition of recorded ground movement or structure reactions [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
