  • Natural factors taken into account in the reconstruction of roads

    The article discusses the natural factors that should be taken into account when designing highways. The following factors have a significant impact on the design of roads: terrain, engineering-geological and hydrogeological structure, climate, etc. The variety of natural factors is taken into account comprehensively in the design. They also take into account the negative impact of road construction on the environment. The terrain has an impact on fundamental engineering decisions, the volume of construction work, and ultimately not only on the construction cost of the highway and transport operating costs. In relation to the design of roads, there are five categories of terrain according to the complexity of road construction. Depending on the geological conditions, sometimes an extension of the highway route is used or expensive engineering measures are provided. It should be borne in mind that the use of the latest materials, road structures and new techniques for the production of construction areas is becoming less and the problems of seasonality of road reconstruction are becoming less relevant.

  • Determination of intensity of movement of motor roads of local importance, located on the Factory highway in Samara

    The problem of major repairs on the factory highway in Samara still remains unresolved, although the issue has been acute for many years. During this time, as statistics show, there were a lot of accidents and damage to vehicles. A heavy load on the roadbed leads to rapid wear of the asphalt surface, as a result, almost every year the Factory highway needs repairs. The load on the highway will increase even more when the section of road connecting the new Kirovsky bridge with the Zavodsky highway is built. The automobile road in Samara along the ZAVODSKOE highway needs major repairs for several years, but the work does not begin, and every spring its condition worsens more and more. The issue remains relevant today.

  • Engineering surveys of road clothing using georadars

    The article deals with the survey of transport and operational condition of the highway R224 " Samara-Orenburg in which it was found that the roadway surface is in poor condition due to the presence of transverse cracks, ruts and pits. In a survey of 5 existing culvert structures were identified unacceptable defects in the structure. Based on the foregoing, the specified section of road be repaired in accordance with GOST R 50597-2017 “roads and streets” . Currently, economical and mobile methods of inspection of road structures are of particular relevance. Conducting engineering surveys of the GPR system MIRA was determined the constructive layers of road clothes light. The decision on milling to a partial thickness of the pavement that runs recyclers WR 4200, with the subsequent device of asphaltgranulate type To

  • Application of geoinformation systems in various directions during construction

    In the construction and use of software technologies, including roads, using GIS and CAD technology. We can also use technologies without data to work with attribute information. GIS is used to manage a large number of different-scale information on construction, reconstruction,etc.Any construction consists of several stages, including the construction of roads, starting, as we see from the planning, then the design and coordination of objects and putting it into operation. GIS during construction is considered in conjunction with all stages., at what first analyze the location of the object on the map. GIS in construction is one of the most important links in the overall planning system.

  • Analysis of Samara city transport during the 2018 world Cup

    Passenger traffic is the number of passengers moving in one direction at a given time. Passenger flows are depicted in the form of graphs, maps, diagrams or fixed in tables. Research methods are divided into the following features; 1) by the length of the period covered 2) In terms of scope 3) by type Methods of automated research: - non-contact method -contact method To ensure the rational filling of the rolling stock, the proper fluctuation of passenger flows, the number, capacity and separation of the rolling stock on the transport network must change. Significant impact on passenger traffic has: the level of development of social production, social structure of society; way of life; geographical environment and the nature of settlement; development of technology; information and communication; budget of free time; cultural, domestic and social needs of people. In connection with the Providence of the world Cup is expected to be a huge number of fans in the city of Samara, for more capacity of fans, the route of personal and public transport has been changed. In the period of the 2018 world Cup will operate on two schemes of movement of vehicles: 1) Daily (in the period from June 14 to July 15); 2) Enhanced (for the period of game matches at the Samara arena stadium ).

  • Channeling of X-ray fluorescence excited in hollow microcapillaries.

    The possibility of channeling X-ray fluorescence inside the hollow microvascular at the energy of the exciting radiation in the vicinity SiL2, 3 - absorption edge has been researched. Theoretically obtained the angular distribution of the field passing through the microchannels. The calculation model of inhomogeneous waveguide layer with the generation of X-ray fluorescence inside the walls of the microchannels shows the possibility of escape of radiation at large angles.
