The system of technical regulation is considered as foundation for the creation of a high construction culture, increasing the competitiveness of the industry in Kazakhstan. Key actions to reform regulatory framework which was established by the government focused on achieving a sustainable balance of economic and social interests of construction participants and consumers. The process of adopting international standards to Kazakhstan soil and construction conditions is gradual. The first step was to adapt foreign technical documentation to the national technological environment. In this way, there were developed appropriate methodologies for assessing conformity to educate builders and designers to develop appropriate training programs, handbooks, and manuals, translation to the Kazakh language, checking the general format of the maintenance of the Eurocodes by comparative calculations, etc. It is important that this process does not contradict the Eurocode relating to any aspects of the requirements in Kazakhstan that are not covered by the Eurocode. The article presents discussions of stages for harmonization and adaptation of Eurocode to Kazakhstan norms.

The article proposes an impregnation composition for cement concrete roads used to improve the ice-phobic properties of the pavement. The composition is based on the keratin production technology. The distinctive component of the composition is the addition of water-soluble polymers. One of the study criteria was to evaluate the performance of the impregnation composition, its adhesion resistance to mechanical impact. Tests were conducted for large samples (surface area 1925 cm2) in laboratory conditions with the application of vibration and shock loads. The test results showed the effectiveness of the ice-resistant coating, as in all experiments the uncoated specimens showed greater resistance of the ice crust to mechanical stress.

Considering the physical chemistry of grinding it is worth quoting the grinding of mineral building material as “the change of physical-chemical properties of finely ground materials can not only be due to the reducing the particle sizes, at mechanical grinding significant changes of the crystalline structure of their surface layers (thickness 15-20 microns) take place, in many cases the technological properties of fine powders are not so much due to dispersability but are namely due to the structure rupture”, at that the energy costs for this are “significantly greater than for the exposal of surfaces with a clean cleavage”. The speed of heterogeneous chemical processes involving fine powders is determined primarily not by the magnitude of their specific surface area, as commonly is believed, but by the decrease of energy of activation as the result of crystalline structure rupture and amorphization. However, both specific surface area and energy demands to achieve are actual evaluation of the effectiveness of any material grinding at a particular unit. The main factor of the production process of cements of low water demand is the grinding, characterized by grindability.

The article is given to consider the issues of madrasahs in Kazakhstan at diverse time stages of the medieval period. The overwhelming significance of old madrasahs within the structure of the city and past is considered. The study is analyzing inclinations within the plan of madrasahs, issues of arrangement of architectural arranging, utilitarian and compositional arrangements. Taking under consideration the pertinence of the strategic importance of these objects which are the legacy of the Turkic-speaking states, within the future, it foreordained the reason of the consideration of this article - to recognize the most bunches of factors that affected the compositional strategies of organizing spaces. Based on this purpose, the accessible chronicled materials made it conceivable to decide the objectives of the study: – uncovering the part of madrasah as a key structure of Islamic education; – investigation of the components affecting the method of shaping; – assurance of the specifics of the building and arrange We advertised the strategy to uncover the philosophical meaning of the structural composition of instructive teaches as a chunk of craftsmanship. The town-planning highlights, structural and imaginative characteristics of the objects of the investigation are described based on the hunt for approaches to the plan of madrasahs where the contact of the ideological views of Islam and the Turkic conventions, both profoundly and structurally is revealed. As a result, the essential guideline within the plan of madrasahs was uncovered. This guideline demonstrates that they were city-forming objects. This made it conceivable to assist recognize the essential standards of Kazakh conventional design of the medieval period. The method of the research moreover analyzes the method of separation of building parameters and changes within the space-planning structure of the objects beneath thought.

The thermal conductivity is crucial for determining heat transfer in frozen soil. However, it is a challenge to obtain accurate measurement values due to the instability of soil properties. Recently, the fiber optic sensing technologies has enabled accurate and distributed in-situ monitoring of a variety of geotechnical parameters. This paper aims to explore the feasibility of actively heated fiber Bragg grating (AH-FBG) method in measuring thermal conductivity of frozen soil. A series of laboratory experiments were performed on frozen soil samples at different initial temperatures from −16 to 5 ℃. The theoretical upper and lower limits of thermal conductivity were used to evaluate the AHFBG measurements. The thermal conductivity recorded by a heat transfer analyzer was used to identify the measurement accuracy. The experimental results that the AH-FBG method can accurately measure the thermal conductivity of frozen soil when the initial temperature is below −6 ℃, and the measurement error is within acceptable range of 0.8%. When the soil temperature is between −6 and 0 ℃, significant measurement errors were observed due to the disturbance of heating to the frozen soil.

This study describes the ways and methods of strengthening the lower and upper structure of the railway track for separate sections with heavy and high-speed train traffic. The dimensions of the rail settlements in the center of the car wheel, methods of reducing the elastic vertical deformations of the upper structure of the railway track under the trains are proposed, the proposed track designs for the heavy traffic of freight trains are given. Increasing the strength of soft soils at the top of the subgrade to the level of strong and hydrophobic ones in a short time, possibly by including soil stabilization of the main site in the program of major or medium repairs of the track. This requires the use of high-performance technologies and mechanization - for example, cold recycling technology. The necessary machines and mechanisms for stabilizing the soil of the main site of the railway subgrade used in transport construction are cement trucks, distributors of cement (or ash-cement mixture), road milling machines and recyclers, motor graders, watering machines, rollers, etc. In addition, the technical requirements for high-speed passenger trains are considered.
