In the article, a necessity to improve the system for accounting of parameters for additional factors of technical condition of vehicles and road environment facilities allowed for during design and construction of motor roads is substantiated. A procedure for the determination of circumstances and causes of road accidents, taking into account transport, technical and operating conditions, has been developed. An improved algorithm of expert examination with the application of a non-destructive method with use of diagnostic equipment of dynamic impact is offered. The accounting system includes an algorithm of expert examination of road accidents which provides parametric characteristics of objects and conditions for their existence to ensure procedure functioning. Criteria to identify "weak"sections of motor roads are proposed. A model for the implementation of expert examination taking into account parameters of the subsystem "Vehicle–Road" is proposed. A possibility to determine the risk of road accidents, "weak" sections of operated motor roads, development of an automated data base on motor roads, application of research results in expert opinions upon analysis and reconstruction of road accidents is substantiated.

This study was designed to assess lead content in soil and two vegetable species collected from several sites in Baghdad. The results showed that Swiss chard had lead content varied from 0.930 ± 0.23 µg/g to 1.988 ± 0.42 µg/g and these data were higher than those found in celery which ranged from 0.216 ± 0.08 µg/g to 0.935 ± 0.22 µg/g. In case of celery plants cultivated in both Al- Autyfia and Al- Qanat sites, lead content has been found to be affected significantly ( P≥ 0.5) by the distance from motor road where higher content was found in plants closed to motor verge than those 15 meter away. For soil lead content, the results showed that lead content was almost two times greater than those of vegetable plant and again lead concentration was affected by the distance from the motorway verge in both sites where lead content varied from 1.512 ± 0.42 µg/g to 2.279 ± 1.04 µg/g and from 2.102 ± 0.82 µg/g to 2.656 ± 0.62 µg/g in Al- Autyfia and Al- Qanat samples respectively. However, these data in celery plants ranged from 1.389 ± 0.36 µg/g to 1.607 ± 0.88 for Al- Autyfia and from 1.359 ± 0.68 µg/g to 1.582 ± 0.92 µg/g for Al- Qanat cultivated yard.

In our time, the problem of proper water disposal systems is acute. Surface water disposal systems.is an engineering system, the main purpose of which is the timely removal of melt and rainwater from the site. This system must work smoothly, because the accumulation of moisture entails many negative consequences for structures, soil, plants, and the like. The rainwater from the site should be as thought out and implemented as much as possible, taking into account the characteristics of each type of site. Special attention should be paid to water disposal systems from highways. Excess water on transport routes and streets poses a very serious hazard to drivers, passengers and pedestrians. In addition, it is the reason for disruptions in transport links. The installation of such a system in the streets should ensure the strength and stability of road structures, as well as create favorable conditions for the operational use of city roads because of the rapid and complete removal of surface water entering the street gutter of a stormwater drainage system. This system is an integral part of the general stormwater drainage system from the territory of the settlement. Therefore, its design is carried out in conjunction with the general drainage system from all over the city and is called stormwater sewer system (drains). That is, it is a sewer that consists of rainwater catchments, sand traps, rainwater gutters, pipes and catch basins. Its primary purpose is to dispose rain, melt water and surface water from internal drainage systems of buildings, too, after watering and washing the streets, receiving water release from drainage systems, from drainage of tram tracks and road drainage of shallow foundation, etc. Therefore, the design of drainage systems in the streets and on the roads is carried out in compliance with the norms and rules specified in DBN B.2.5-75 and DBN B 2.3-5: 2018. , У наш час гостро стає проблема правильного водовідведення. Поверхневий водовідвід – це інженерна система, головною метою якої є своєчасне видалення талих і дощових вод з ділянки. Дана система повинна працювати безперебійно, адже накопичення вологи тягне за собою безліч негативних наслідків для споруд, ґрунту, рослин тощо. Система водовідведення повинна бути максимально продуманою і реалізованої, враховуючи особливості кожного виду ділянки. На окрему увагу заслуговує водовідведення з автомобільних доріг і вулиць. Зайва вода на транспортних шляхах і вулицях створює дуже серйозну небезпеку для водіїв, пасажирів і пішоходів. Крім того, це причина перебоїв у транспортному сполученні. Облаштування такої системи на вулицях повинно забезпечити міцність і стійкість дорожніх конструкцій, а також створити сприятливі умови для експлуатації міських вулиць через швидке та повне видалення поверхневих вод, які надходять до дренажних лотків доріг. Ця система є складовою частиною загальної системи водовідведення з території населеного пункту. Тому її проектування проводиться в комплексній ув'язці із загальною системою водовідведення з усієї міської території і називається дощовою або зливовою каналізацією (водостоками). Тобто це така каналізація, яка складається із дощоприймачів, пісковловлювачів, дощоприймальних жолобів, труб та колодязів. ЇЇ основне призначення це відведення дощових і талих вод, а також поверхневих вод з систем внутрішніх водостоків будівель, після поливу й миття вулиць, приймання випусків води з дренажних систем, від дренажів трамвайних колій і дорожніх дренажів мілкого закладання тощо. Тому проектування систем і споруд водовідведення з вулиць і доріг здійснюється з дотриманням норм і правил зазначених у ДБН В.2.5-75 та ДБН В 2.3-5:2018.

Introduction: the methods of roadside service network development implemented in Belarus were identified. Structure, architectural and spatial solutions, and general functional zoning of a service facility territory were considered for the roadside service facilities located along Belarus main motor roads. The study aims at the revelation of typological features of roadside service network elements in Belarus and their structure-based classification as well as the development of the main provisions on the formation of these facilities based on the current situation analysis and prospective lines of building up a service system in the areas of influence of national importance roads. Materials and methods: the work was carried out through systematization, structural and comparative analyses, theoretical synthesis of the data obtained from the detailed analysis of literature and statistical sources, field surveys of roadside service facilities located along the national-importance roads in Belarus. Likewise design estimation documentation for the constructed facilities was applied. During the field surveys, photo fixation and graph-analytic analysis methods were used. Results: the article suggests the classification of roadside service facilities, reveals the methods of network development, considers functional zoning and offers a concept of prospective formation of the facilities in Belarus. Conclusions: theoretical and methodological foundations of the facility formation were developed, which allows accomplishing more reasonable and objective decisions regarding the development of the roadside service network. The developed classification allows defining new approaches to the formation of the network individual elements. The suggested concept of a modular system for the prospective formation of the roadside service in Belarus can form a basis for the initial build-up and temporary transformation of the facilities and the system as a whole and can be used to develop regulatory requirements for their planning structure and architectural and spatial solution.

У дорожньому будівництві якість продукції часто оцінювали спрощено з урахуванням лише технічного аспекту ототожнюючи, як правило, з якістю матеріалів, які використовували або закінчених конструктивних елементів. У той же час, кінцевою продукцією – є автомобільна дорога, що призначена для здійснення безпечних вантажних і пасажирських перевезень протягом строку її служби. До того ж існуючі мережі вагових комплексів просто не встигають ефективно обробити потоки вантажів: їх найчастіше взагалі недостатньо для зростаючих трафиків перевезень, крім того, місця їхнього розташування неоптимальні з точки зору переважних напрямків пересування відповідного транспорту. Реконструкцію вагової мережі необхідно робити або надзвичайно швидко (що реально мало ймовірно), або частинами (що вкрай ускладнює планування проекту), щоб не залишати транспортну ділянку без вагового контролю транспорту взагалі. Метою роботи було створення ефективної системи підтримки прийняття оптимальних проектних рішень в процесі управління проектами та програмами реконструкції вагових автошляхових комплексів, які засновані на гнучкому використанні рухомих тимчасових елементів та покликані здійснити революцію в продуктивності перевезень без одночасної руйнації доріг. На жаль, єдиний метод боротьби з цією проблемою є жорсткий контроль ваги безпосередньо на автошляхах за допомогою мережі вагових комплексів. Це означає, що така мережа повинна постійно підлаштовуватися під напрямки та завантаженість транспортних засобів, а також під поточний стан окремих ділянок дороги, для чого необхідно постійно реалізовувати послідовні проекти реконструкції вагових комплексів. Показано, що така реконструкція супроводжується великими ризиками та проблемами, які випливають із багатофакторності та малопередбачуваності процесів, які таку реконструкцію супроводжують, а отже вони потребують нових підходів, моделей та методів проектного управління. Насамперед це торкається цілепологання при плануванні проектів, структури проекної діяльності та обрання компетентних проектних організацій., In the road construction, product quality has often been evaluated simplified, taking into account only the technical aspect, identifying, as a rule, the quality of materials used or completed constructional elements. At the same time, the final product is a road that is designed to carry out safe cargo and passenger transportation during its term of service. In addition, existing networks of weighing complexes simply do not have time to effectively handle cargo flows: they are often not enough for increasing traffic; in addition, their location is not optimal in terms of preferred directions of the transport movement. The reconstruction of the weighbridge must be done either extremely fast (which is really unlikely) or parts (which complicates the planning of the project) so as not to leave the transport area without weight control at all. The purpose of the work was to create an effective system of optimal design solutions support for the adoption in the management of projects and programs for the reconstruction of heavy-duty road systems, based on the flexible use of moving temporary elements and designed to revolutionize the productivity of transportation without simultaneous roads destruction. Unfortunately, the only way to combat this problem is to strictly control weight directly on the highway through a network of weighing systems. This means that such a network must constantly adapt to the directions and load of vehicles, as well as the current state of the road individual sections, which requires constant implementation of successive projects for the reconstruction of weights. It has been shown that such a reconstruction is accompanied by high risks and problems arising from the multifactority and unpredictability of the processes that accompany such a reconstruction, and therefore they require new approaches, models and methods of project management. First and foremost, it addresses the aim of the project planning, project design and selection of competent design organizations.

Traffic safety mainly depends on vehicles, pedestrians and road infrastructure. On highways, the heaviest traffic accidents are associated with crossing of the dividing strips by a vehicle and its collision with side obstacles on the junction or road bridge exit. These accidents often occur, when vehicles, running at a high speed, collide with obstacles, which may cause human injuries. In such cases, the probability of fatalities or heavy injuries to people in a traffic accident is very high. Road traffic infrastructure plays an important part in ensuring traffic safety on urban roads and highways. It includes guardrails, speed bumps, pedestrian safety islands, traffic regulation systems, road information infrastructure, etc. Guardrail (known as civil engineering element and traffic safety element) installation may help to reduce the number of human injuries and fatalities caused by traffic accidents. Guardrails of various types are installed on the roads of Lithuania and Ukraine. Guardrails, consisting of metal posts of the profile Σ and a protective beam of the profile W, i.e. ‘double-wave guardrails’, are among the most commonly used ones. The authors of this paper present the analysis of the deformation state of a double-wave guardrail (describing the strains and stresses of its elements).

В России большинство автомобильных и железных дорог защищены лесными полосами. В настоящее время в засушливых условиях Ростовской области не уделяется должного внимания научным разработкам по вопросам создания, содержания и реконструкции защитных лесонасаждений вдоль автомобильных дорог. Целью работы является анализ состояния придорожных защитных лесонасаждений и совершенствование технологических аспектов их создания на примере участка автомагистрали г. Новочеркасск – пос. Каменоломни Ростовской области. Мониторинг придорожных защитных лесонасаждений выявил, что в степных условиях со сложным орографическим рельефом, наряду с защитой от снежных завалов одной из важных функций является эстетическое оформление местности. Протяженность защитных лесных насаждений, как объекта исследований и озеленения – 17 800 м. Маршрут относится к одной из главных магистралей на г. Шахты и федеральную трассу М4 Ростовской области. Определение потребности в создании придорожных лесных полос выявлялось с использованием GPS-навигатора (GPSmap 62s). Проведен анализ состояния придорожных защитных лесонасаждений на рассматриваемом отрезке автомагистрали и установлен их видовой состав. В соответствии с почвенно-климатическим условиям обоснован ассортимент растений с предпочтением устойчивости к снеголому, декоративности, успешности защиты автодороги от заноса снегом и пылью. Определены объемы посадочного материала с участием Quercus robur, Acer platanoides, обоснована система подготовки почвы, видовой состав, схема размещения. На всей протяженности исследуемого участка (17,8 км) требуется создать защитные лесонасаждения (4 лесные полосы протяжённостью 998,0 м, шириной – 12,0 м, площадь 1,2 га). С научным обеспечением и учетом региональных особенностей создания защитных лесонасаждений вдоль автомобильных дорог (конструкция насаждений, ассортимент, методы выращивания, лесоводственные уходы и др.) они способны выполнять свои функции в полном объеме к возрасту 25 лет., In Russia, most roads and railways are protected by forest belts. Even a single row of trees provides good results in road surface protection from snow. At present, in the dry conditions of the Rostov region is not given due attention to scientific developments on the creation, maintenance and reconstruction of protective forests motor roads. The goal of this work (publication) is to analyze the state of roadside protective forest plantations and improve their creation on the example part of the highway of Novocherkassk - Kamenolomni of Rostov region. Monitoring of roadside defensive forests showed that in a steppe environment with complex orographic relief, along with protection from snow clogging, one of the important functions is the aesthetic design of the terrain. The length of protective forest plantations as a research and planting site is 17 800 m. The route is one of the main thoroughfares to the city of Shakhty and the federal highway M4 of the Rostov region. Determination of the need for creating roadside forest belts was detected using GPS-navigator (GPSmap 62s). The condition of roadside protective forest stands on the considered segment of the motorway and their species composition is established. In accordance, with soil and climatic conditions, an assortment of plants with a preference for resistance to snow, decorativeness, and the success of road protection against snow and dust drift are justified. The volumes of planting material with the participation of Quercus robur, Acer platanoides, are determined, the soil preparation system, the species composition and layout. Over the entire length of the investigated area (17,8 km), it is required to create protective forest stands (4 forest belts with a length of 998 m, a width of 12,0 m, an area of 1,2 hectares). With scientific support and consideration of regional peculiarities, creation of protective afforestations along highways (design of plantations, assortment, methods of cultivation, silvicultural care, etc.), they are able to perform their functions in full by the age of 25 years., №2 (2018)

Traffic safety mainly depends on vehicles, pedestrians and road infrastructure. On highways, the heaviest traffic accidents are associated with crossing of the dividing strips by a vehicle and its collision with side obstacles on the junction or road bridge exit. These accidents often occur, when vehicles, running at a high speed, collide with obstacles, which may cause human injuries. In such cases, the probability of fatalities or heavy injuries to people in a traffic accident is very high. Road traffic infrastructure plays an important part in ensuring traffic safety on urban roads and highways. It includes guardrails, speed bumps, pedestrian safety islands, traffic regulation systems, road information infrastructure, etc. Guardrail (known as civil engineering element and traffic safety element) installation may help to reduce the number of human injuries and fatalities caused by traffic accidents. Guardrails of various types are installed on the roads of Lithuania and Ukraine. Guardrails, consisting of metal posts of the profile Σ and a protective beam of the profile W, i.e. ‘double-wave guardrails’, are among the most commonly used ones. The authors of this paper present the analysis of the deformation state of a double-wave guardrail (describing the strains and stresses of its elements).

The state of hot mix asphalt pavement and its structure, predetermined by the distress level, largely depends on the functional conditions. The factors predetermining the functional conditions and service life of hot mix asphalt pavement and its structure are discussed in the present article: traffic loads, local climate and weather conditions, local soils (their properties), and other local factors (soil water level and moisturizing conditions, etc.). It is shown that the state of the road pavement and its structure expressed in the distress level, the roughness of hot mix asphalt pavement strength, expressed by strength coefficient Kst, largely depends on the componential composition of the upper layer of hot mix asphalt pavement and its physical and mechanical properties. The article contains recommendations for maintaining the required state of hot mix asphalt pavement and its structure (when D ≤ 8%) and for renewal of the service life of the pavement and its structure.
