The article deals with the approaches to construction of a multi-level hierarchical system indicators for evaluation quality state motor road section. model weight parameters and characteristics roads as road-transport asset included in information management monetary was developed. need research caused by necessity develop unified qualimetric As result, structural elements were analyzed, which made it possible consider object – section from standpoint methodology constructing complex...

The object of this study is the theoretical and methodological approaches to determining coefficient moisture conductivity subgrade soils. work focuses on considering European standards when devising a method for In course research, was developed soils K1, which characterizes diffusion movement water, through filtration K0, calculated in accordance with requirements based laboratory test data. proposed mathematical model built basis differential equation changes soil moisture. special that,...

Annotation: The study presents the results of research impact traffic intensity and flow composition on capacity highways bridge crossings based mathematical numerical modeling methods. main factors affecting have been identified. methodology for determining level approved by State Service Highways (now Restoration Agency) was adopted as calculation basis modeling. Also, calculations, updated statistical data, given in open literary sources, were used. 11 test options with different...

The article is devoted to the problem of improving durability cement concrete cover road through use additives. purpose work-improving roads hydrophobic Object study-cement-concrete roads. Method research: statistical analysis scientific publications, technical and normative literature. In Ukraine, there are almost no necessary types brands cement, so research application existing binders with effective additives an urgent problem, solution which will expand nomenclature for Construction,...

The processes forming the humidity mode of drainage layer a road structure under action excess load have been investigated. stressed-strained state was determined based on numerical experiment using software-calculation suite SCAD Office. modeling examined involved static А2 group for category II. A series experiments were performed, which included an increase in rated by 10–50 % when overwetting and earth bed. distribution isofields isolines normal stresses deformations volumetric elements...

Summary The article describes the general concept of creating single information analysis system for recording proprietary rights to land plots public road Ukraine. requirements current laws and regulations normative documents are taken into account. Critical systematization key problems in direction research were carried out.

The article is devoted to operational quality control of grainsize composition cement-concrete road mixtures for use on highways Ukraine. results the experimental research are presented, which testify non-conformity planned grain actual production composition, as well influence it a number factors that significantly affect mixture and durability cement concrete.

An important aspect of the road structure strength and stability ensuring is issue subgrade favorable water-thermal regime providing during service life. The article analyzes results research by scientists from different countries on issues taking into account humidification arrangement drainage system highways. One main design parameters shallow transverse drainages distance between slots. exact definition this indicator determines efficiency water planar makes it possible to optimize cost...

The article covers the issue of development, approval, implementation and further use a domestic stabilizing additive for production stone-mastic asphalt mixes. prerequisite creation such project was development latest technologies road construction materials, both on world Ukrainian industry markets, as well annual growth in need materials during infrastructure projects. Based results work, it established that quality domestically produced corresponds to level similar imported goods, its...
