Integration of the Moscow Central Ring and Central Diameters into the capital's transport system

Troitskaya N.A., Titova S.S.

Abstract:
The development of the Moscow transport complex is of great importance for improving the quality of service to residents and strategic for the economic growth of the region. In 2016, the opening of the Moscow Central Ring (MCC) took place, the construction of which began at the end of the XIX century. Ground rail transportation of passengers along with the usual urban public transport is a natural way of development for many large cities of the country.

Keywords:
central ring and diameters of Moscow, metro, railway, transport system of the city, passenger transportation



Modern tunnelling: the cost of construction and the price of non-standard situations

Merkin V.E., Petrova E.N.

Abstract:
Different ways of the development of transport tunnelling analysed and considered from non-standard situations.

Keywords:
cost, damage, non-standard situation, tunnelling



Research into the process of cooling of cast asphalt concrete mixtures during road paving

Kozikov I.O., Lupanov A.P., Silkin V.V., Sukhanov A.S.

Abstract:
On the basis of a mathematical model, the cooling rate of cast asphalt concrete mixtures is calculated for different versions of pavement structures. Dependingon the initial temperature of the mixture, air temperature and wind speed during the laying process, the time at which the required mobility of the mixture is provided is determined.

Keywords:
air temperature, asphalt concrete pavement, cast asphalt concrete, cast asphalt concrete mixtures, cooling rate of cast mixtures, mobility of the mixture, sub-zero temperatures, wind speed



Durability of adhesive joints of bitumen in asphalt concrete

Bashkarev A.Y., Lazarev Y.G., Bessonova V.Y., Ismailov A.M.

Abstract:
The possibility of prediction of durability of bitumen and its adhesive bonds with the help of thermofluctuational theory of strength has been substantiated. It has been theoretically and experimentally proved that the maximum adhesion strength of bitumen depends not only on the temperature in the process of material bonding, but also on its duration.

Keywords:
bitumen, durability, granite, prediction, strength, temperature, time



Selection of a type of waterproofing for bridge structures under cast hot asphalt concrete

Valiev Sh.N., Kamenskih A.N., Kochetkov A.V.

Abstract:
A comparative analysis of the use of roll-fed and sprayed hot polymer waterproofing of bridge structures is carried out.

Keywords:
bridge construction, durability, ground, macadam-mastic asphalt concrete, mastic asphalt concrete, pasting, reliability, risk, roadway, spraying, waterproofing



Modernization of the GPS/GLONASS-based avant-garde position tracking system

Khazanov M.L., Vasiliev A.I.

Abstract:
The features of the modernization of the software for monitoring the position of the launching nose using the geodetic satellite system GPS /GLONASS are described. The article is a continuation of the article published in the issue 3 of the magazine in 2015.

Keywords:

Testing of precast prestressed reinforced concrete beam 12 m long under precast-monolithic bridge spans

Ageyev A.V., Sapronov I.M., Gromozdin S.V.

Abstract:
The preparation for bench tests of a precast prestressed reinforced concrete bridge girder designed for precast-monolithic spanning structure revealed the need to develop a special approach to the methodology, both in the calculation-theoretical pre-test analysis and for the test process itself. The test results made it possible to verify the calculations, which were especially important for testing the girder in the state of shipment from the factory, and to draw some important conclusions and recommendations for similar practical investigations of precast-monolithic bridge structures performance.

Keywords:
bench tests, full-scale experiment, installation of test load, measurement of deflections and relative deformations, prefabricated monolithic superstructure, prefabricated prestressed reinforced concrete beam, verification of calculations by tests



Special feature of calculating the strength of rigid airfield pavements

TatarinovV.V., FominA.V.

Abstract:
As a result of the study, the features of the application of this method for the airfield pavement made of reinforced concrete, designed for the load from the B-767-200-ER aircraft, were investigated. Based on the results of the calculation, the values of deflections and bending moments in the edge zone of the reinforced concrete slab were determined, and their diagrams were constructed for various applications of the aircraft support wheels. This study will make it possible to refine the transition coefficients used in the calculation of the strength of airfield pavements of a rigid type.

Keywords:
bending moment, concentrated force, elastic foundation, main support, method of compensating loads, plate, pneumatic wheel, rigid airfield pavement



Improvement of slope stability of earth bed embankment from barchan sands

Abstract:
The article presents a calculation of the stability of the slopes of the embankment of an earthen bed made of sand dunes. Soil characteristics and earth bed design are taken from geotechnical reports and existing railway designs. Numerical model of earth bed embankment has been developed in Plaxis 2D software package. Stability calculations of earth bed slopes and full model deformations without and with reinforcement by geosynthetic materials have been performed. Comparative analysis of calculation results of two constructions was carried out. Theoretical calculations have shown advantages of application of geosynthetic materials for reinforcement of railway bed slopes.

Keywords:
anchor, earth bed, reinforcement, slope, stability, stability coefficient, volumetric geogrid



Temporary construction infrastructure of linear objects: nomenclature, device requirements and organization conditions

Zhuravlev P.A., Marukyan M.A., Abdrakhmanov R.S.

Abstract:
The organization of work on the preparation of construction sites for the start of construction includes a wide range of organizational, technical and technological preparation activities carried out both during the preparatory period and during the entire period of construction and installation works, as well as the liquidation of the construction object. The nomenclature of temporary construction infrastructure of linear objects is described. The requirements for temporary construction infrastructure during the construction and reconstruction of linear facilities, justifying the availability of solutions for design, working and organizational and technological documentation, are considered.

Keywords:
design, linear construction object, organizational and technological design, organizational and technological documentation, temporary construction infrastructure, working
