The development of industry, the use of various chemicals in technological processes, the large emissions of industrial enterprises, the use of pesticides and chemical fertilizers in agriculture have caused environmental pollution with harmful substances. Environmental protection is now becoming one of the economic problems and is an extremely urgent task of humanity. The purpose of this article is to present the main results of the study and analysis of atmospheric air pollution by the asphalt plant, which is located almost in the center of Yekaterinburg; to investigate the compliance of the existing hazard class of the enterprise, which increases its production volumes, to correct the size and location of the sanitary protection zone of the plant, taking into account the wind rose, and to try to propose a number of measures to reduce the negative impact of the plants in this industry. In considering the impact of anthropogenic activities on nature, attention should be paid to the concept of sustainable development, which carries principles based on the satisfaction of human needs, with a focus on caring for the well-being of future generations. If we consider the issue from the perspective of this concept, then the asphalt plant, in order to prevent possible environmental damage, should invest material and money to further minimize the amount of pollutants.

“…These emissions could be controlled, but most asphalt plants in Russia do not have adequate provision for pollution monitoring devices. During production activities, fuel combustion products, such as carbon oxides, soot, benz(a)pyrene, and sulfur dioxide, enter the atmospheric air [4,5,6,7,8,9].…”

Characterization of Asphalt Aging by Analytical Techniques: A Review on Progress and Perspectives

2022

This review describes the chemical composition of asphalt, which is relevant for the development of materials with higher quality and durability. Asphalt aging can occur in the short term (during machining and storage periods) and the long-term (during the time the pavement is exposed to the environment). To understand the effect of aging on the chemical and physical properties of asphalt, we reviewed the short-term (rolling-thin film oven test (RTFOT) and its variations) and long-term (pressure aging vessel (PAV) and its variations) aging methods and the effects of the sun’s ultraviolet radiation (Suntest and its variations). We also explored the main chemical reactions that occur in the aging processes, such as oxidation, polymerization, and aromatization. For a more accurate assessment of the classes of compounds that undergo aging reactions, fractionation techniques have been developed over the years, such as separation of asphalt into saturates, naphthenic-aromatics, resins, asphaltenes, organic sulfides, nitrogenates, and oxygenates, among others. Despite several studies on the theme of asphalt aging, it is still necessary to understand the phenomena that occur in those processes.

“…Gschösser et al [16] achieved similar results; the authors found that pavement construction and deconstruction have less impact on the pollution than the material production, transporting and recycling processes. Furthermore, Wang et al [17] noted that the volatile organic compounds generated during asphalt pavement production have a negative impact on the atmospheric ecosystem and that this problem has raised increasing concerns globally in recent decades. Itoya et al [18] also revealed that asphalt production, compared to other processes, led to the most significant carbon emissions.…”

The Correlation between the Number of Asphalt Mixing Plants and the Production of Asphalt Mixtures in European Countries and the Baltic States

2021

View full text Add to dashboard Cite

The transport infrastructure’s pavement is made of asphalt layers, placed and compacted. The asphalt mixture is produced in an asphalt mixing plant (AMP) using expensive technological equipment which, when it becomes obsolete and worn out, is replaced with new equipment. One of the main problems related to the replacement process is that when it comes to purchasing new AMPs, the decision making involved is, in most cases, highly intuitive due to a lack of clearly defined criteria. In order to remedy this situation, this work presents an analysis of the correlation between the number of AMPs and the production of asphalt mixtures. Firstly, a correlation analysis was performed based on the European Asphalt Pavement Association (EAPA) data. Secondly, the current situation with the AMPs in European countries was analysed. Furthermore, a case study was performed and a system of nine criteria was created to identify why/when road construction companies operating in the Baltic States buy new AMPs. The weights of the criteria have been established by applying the Analytic Hierarchy Process (AHP) method. It was found that the most important criterion during the decision-making process for road construction companies is increased requirements for improving the quality of the asphalt mixture produced (criteria weight 25.0%). With a weight of 20.6%, the second vital criterion is the possibility of receiving support from European funds. The third criterion is the expectation of having a sizeable asphalt-paving site (weight 20.4%). The other six criteria are also significant, their weights varying between 1.6% and 13.5%. The industrial companies can use the obtained results for designing, producing and selling AMPs and adjusting strategic business plans.
