Introduction. The active development of the transport network of highways is one of the areas of construction activities, the environmental safety of which does not fully comply with environmental requirements. The road transport complex has a negative impact on all existing components of ecosystems, but the greatest impact is associated with the formation of waste generated during the reconstruction of highways. To minimize the negative impact of the road construction complex waste management on environmental components, it is necessary to supplement the well-known methods of assessing the created schemes and methods with approaches associated with the analysis of environmental safety. Materials and methods. Due to the fact that most of the waste generated during the reconstruction of highways is multi-composite, a classification by enlarged types is proposed, depending on their chemical composition and state of aggregation. Results. For the numerical assessment of the biopositivity parameter in the comparative analysis of various technologies, the method of hierarchy analysis was tested, which is based on the principles of decomposition, pairwise comparisons and synthesis of priorities. In general, the assessment of biopositivity is a hierarchical procedure that includes operations related to the transformation of the scale and its aggregation. The most significant factors reflecting the impact of the technologies under consideration on the environment were selected as the criteria for the assessment. Conclusions. The presented calculations of the biopositivity parameter for the considered methods of reconstruction of highways in swampy areas showed that the peat technology has the least impact on the environment. The bio-positivity index during peat extraction is 2 times higher than when using geocontainer processing of wetlands.

Abstract. Problem. The issue of the impact of construction projects on the environment is extremely relevant and complex. Analysis of publications. The study of the negative impact of rolling stock, dust, noise, vibration, emissions during the operation of engines, as well as the impact of construction processes on the environment were engaged in such scientists as I.Ye. Evgeniev, RA Kizima, D.W. Зерка-лов, М.В. Немчинов, О.Л. Boychenko and others [1, 3, 4, 8, 9]. The aim is to assess the degree of impact of the road and transport on the environment. Presenting main material. Consumer properties of roads are a set of indicators that directly meet the needs of road users: safety, speed, continuity, comfort of traffic; road capacity, in particular the ability to pass cars and road trains with permitted axle loads, total weight and dimensions; ecological and aesthetic condition of the road; level of service and information support [2]. Ecological safety of the highway depends on the technical level, operational condition of the road and road structures, intensity and composition of traffic and characterizes the impact of the road on the environment within the limits of environmental standards, including harmful vehicle emissions, noise pollution, migration of animals, reptiles etc. [6]. Cars with gasoline engines are especially harmful in this regard. Diesel engines have a much lower level of toxicity and contain much less harmful substances. On the entire area of land occupied by the road and the construction of the road complex, on temporarily allotted land for reserves, quarries and other developments should be removed fertile layer of soil with bulldozers that cut and move the soil some distance. In the course of performance of this work the soil is exposed to mechanical disturbance. The construction area becomes a category of disturbed lands, which include lands with a removed or covered humus layer, not suitable for agricultural and forestry use without prior restoration of fertility [3, 7, 10, 11]. Conclusions. In order to protect the environment, many countries around the world are introducing laws designed to limit the negative impact of vehicles on the state of the biosphere, which requires the creation of modern environmental legislation and regulatory framework for environmental safety.

In recent years, the state of the road transport infrastructure in Ukraine has deteriorated significantly. With the process of urbanization and the expansion of the transport infrastructure, the ecological danger of the functioning of these strategically important objects increases, which requires effective methods of detailed study of the state of environmental components in areas of urban pollution in order to prevent negative consequences. Working with the problematic, using robots, we analyzed the methods to monitor the environmental situation around the road transport infrastructure for the development of recommendations for advancing efficiency. An algorithm for assessing the environmental situation around the objects of motor transport infrastructure is considered, based on monitoring the impact of these objects on the components of the environment and determining the main factors of this influence. The regularities and dependences of the influence of the motor transport infrastructure from the standpoint of environmental safety have been established. The indicators of pollution of the components of the environment in the study areas and methods of their production are analyzed. It has been concluded that a complex combination of chemical research methods with biodication is observable, makes it possible to analyze the effect of vehicles on various components of the environment (atmospheric air, soil and soil solutions, plants, animals, surface waters, etc.) and to establish the level of anthropogenic load.

The role of legislation and state policy in minimizing the impact of threats to environmental safety in the field of automobile transport has been studied. The main directions of the development of state policy and legislation in the field of reducing the negative impact of motor vehicles on the environment and public health have been defined. The main problems of reducing the negative impact of motor vehicles on the environment and public health, as well as the development of state and legal mechanisms to overcome them have been determined. The main environmental problems faced by governments are the use of internal combustion engines and fuel quality indicators. Many EU countries are refusing to further impose more strict requirements on the operation of motor fuel engines, instead introducing mechanisms to completely abandon such vehicle propulsion systems. However, such a refusal raises another problem of greening of road transport – the problem of electrification of transport, in the process of which it is necessary to solve the problems of transport energy and disposal of used batteries of electric vehicles. The authors have emphasized on inexpediency that to be limited in the long run only to mechanisms for setting more strict emission requirements for cars. The authors have indicated the need for a comprehensive approach to solving environmental problems to prevent the emergence of new significant difficulties – the accumulation of used batteries of electric cars, the depletion of non-renewable resources for their manufacture, etc. It has been offered to join Ukraine to the pan-European initiative of electrification of road transport, to develop the state program for the transformation of the motor transport industry with clear deadlines for the introduction of restrictions on the use of internal combustion engines, to introduce mechanisms to financially stimulate the transition from internal combustion engines to electric combustion engines.

Abstract:For a total of 17 mo, we investigated the impact of a road constructed through pristine tropical lowland rain forest, on the composition and structure of the resident anuran community in the Ulu Temburong National Park (Brunei Darussalam). One year after road construction, eight new anuran species had immigrated into the impacted area. Encounter surveys were conducted and radio-transmitters attached to a total of 16 frogs to identify habitat use and distribution of the largest (>130 mm SVL) immigrant species (Limnonectes ingeri) in comparison with a similar sized resident congener. A strong preference for roadside habitat was found for the immigrant. However, several incursions of more than 500 m beyond the road into the pristine forest were also recorded. Over 200 stomach content samples as well as stable nitrogen isotope ratios of 76 individuals were used to assess the trophic ecology of the two species. Invertebrate diet composition did not differ. However, the immigrant species ate over 400% more frogs than its resident congener and had a significantly higher δ15N ratio, indicating a higher position in the food web. This suggests that L. ingeri acts as a new top frog predator in the system and indicates that it may have a significant negative impact on the local anuran community. Overall, road construction in the absence of logging has led to the immigration of new frog species with impacts far beyond the linear disturbance of the road itself.

Construction Defects

The need to build and run roads offering structural integrity led to great advances in the fields of material sciences and fracture mechanics, but construction defects occur to either the new roads or the old ones. There are generally four categories of construction defects referring to roads: construction deficiencies, design deficiencies, material deficiencies, and subsurface deficiencies, but it is not uncommon for a design deficiency to link on to construction deficiencies in the structure.The paper aims to emphasise that people think different about hazard and safety especially when they build roads. Differently put, roads rely more heavily on their makers and users to limit both the occurrence and impact of human error in construction and maintenance on the one hand and to rectify and rehabilitate on the other hand to improve the safety performance of road transport systems and keep accidents from occurring.The paper aims to provide information about the defects occurred in the road construction and maintenance affecting human safety bringing forward practical examples. Moreover, it examines the materials widely implemented in the road construction from the viewpoint of their technological restraints and possible deficiencies. It also analyses some of the methods used on fields about how they might positively influence the road reliability and the human security implicitly.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.
