The increase in the economic efficiency in many industries (energy, mineral resources, metallurgy, chemical coal, construction) is associated with new materials with unusual combination of physical, mechanical and chemical properties. Glass-ceramic materials obtained by directional glass crystallization rank first among others. Compared to crystalline substances, glass has increased internal energy (latent energy of crystallization). Therefore, the substance in the glassy state is metastable (thermodynamically unstable). Ordinary glass under certain conditions begins to crystallize, sometimes, spontaneously. This process is called drying or devitrification. A thermodynamic model is proposed based on the concept of dynamic equilibrium of energy and matter flows during phase transitions in non-equilibrium open systems. The model considers thermal force of the metasilicate crystal growth. Some of the main dependencies of kinetic parameters on thermodynamic properties are suggested for М₂М₁[Si₂O₆] metasilicate composition. The crystallization temperature growth occurs as the overall basicity ∆Ζ^о₂₉₈ increases against relative increase in the basicity of ions in the cationic sublattice M₂ and, especially, in the octahedral sublattice M₁.

A completion of the industrial stage in many industries began late in the 20th century. Measures to reduce the energy and metal consumption and improve the quality of functional materials by attracting new functional composite materials with the addition of modifying and nanoreinforcing filler wollastonite are discussed herein. The main directions of wollastonite use are determined rather by acicular crystals and their color (up to finely white) and chemical composition. In order for the country to participate in the inevitable modernization of mechanical engineering, construction industry and entire economy, it is proposed to study the experience of foreign countries, primarily such as Japan, and begin to implement scientific results obtained in Tomsk universities in the field of experimental and technical mineralogy and materials science.
Research findings: A large deposit of natural wollastonite is discovered in the host metasomatic formations of a gold ore deposit in the Altai Mountains. Methods for obtaining synthetic acicular wollastonite are created. Numerous studies show advantages of wollastonite and its merits in comparison with other traditional materials used in many composite materials, ranging from paints, paper, dental, surgical materials, ceramics, glazes and others.

Negative consequences of global climate change and rapid urbanization are problems of combating urban floods, underflooding and increasing the safety of adjacent water bodies due to the washout of storm water and municipal waste. These problems are being solved slowly and ineffectively. This is explained by harsh climatic conditions in a large number of territories, higher number of abnormal rainfalls, insufficient financial injections into the construction of storm systems from the state and business structures, imperfection of regulatory documents based on outdated information for calculating projects. Conclusions are formulated on ways out of the crisis situation in the city of Tomsk (Western Siberia). It is proposed to improve the collection and drainage of atmospheric water from road sections.
The relevance of the work is associated with the improvement of the system of atmospheric wastewater removal from the road pavement and urbanized areas, especially at abnormal volumes of rainwater.
Purpose: The aim of the work is to assess environmental, economic and technological potential of Russian and foreign techniques to ensure effective storm water drainage and primary treatment of surface runoff.

Research findings: The paper highlights foreign achievements and problems of drainage and storm water treatment from urban roads. Increasing interest in biophilic engineering technologies includes stages of collection and removal of surface runoff water, its primary treatment, and evaporation or infiltration into deep aquifers. The state of the drainage problem in Russia is considered herein. Modern technical means capable of organizing a road drainage system and, if necessary, treating storm water are investigated. The main reasons for the unsatisfactory condition and insufficiency of road drainage systems are identified.
Practical implications: Systematization and generalization of approaches to combating excess urban storm water serve as the basis for improving modern drainage systems in Russia. Foreign experience in draining, isolating, and recycling storm water can be used and developed in different natural and climatic zones of Russia with respect to the specifics of their geoecological situation.

The wear of the road pavement is a widespread problem both in the Russian Federation and abroad. This work studies factors influencing the untimely wear of road pavements. The article considers the pavement changes along the rolling lanes that increase the risk of accidents in certain circumstances: aquaplaning (loss of the tire adhesion to the road surface due to a water layer), lane-change, ice on the pavement surface, etc. The article analyzes the main causes of track formation (traffic flow, load from rolling stock, constant braking and starting of vehicles) and reconstruction of vehicles is considered in detail as the least studied factor, but making a significant contribution to the untimely pavement wear. The main types of lane-change and the places of greatest commission are determined. Experimental studies concern collection of statistical data on the traffic flow, flow composition, track depth that are necessary to assess the impact factor of vehicle lane change. The road pavement wear is revealed during the monitoring of the street and road network in Tyumen. A tendency to increased wear in places of frequent rearrangements in comparison with places of their absence or minimal number was established after comparing the rut size.

Being one of the world's developing countries, Myanmar experiences a significant surge in bridge construction. It, however, suffers resource limits in the bridge sector, which may result in quality difficulties during the construction process. There are serious concerns with the maintenance of some Myanmar bridges, particularly the older ones. Some old bridges in Myanmar were built with limited time, materials, and they are currently in critical need of renovation. While the creation of new infrastructure plays an important role in Myanmar’s transport sector, maintenance of the existing bridge infrastructure is also necessary to ensure its continued safe development.
This article presents a dynamic approach to integration of information and parametric modeling of revovation of steel truss bridges in Myanmar. A brief assessment is given for the current situation of steel truss bridges in Myanmar. The Grasshopper visual programming language is utilized for creating parametric scripts, and the model is able to integrate into information modeling tools such as Tekla Structures and Midas Civil for additional details and strength analysis. The integration of the truss parametric model into numerous software packages improves the flexibility of design automation process, saving time and effort. The design approach makes it possible to get several variants of the same model in a single file, and the process of building a complicated structure like a bridge becomes considerably simpler and more efficient. The results show significant improvements in time savings, alternative design selection, and structural performance. Furthermore, this approach has the potential to revolutionize bridge design, leading to more cost-effective and efficient structures that meet contemporary demands of the transportation infrastructure.

Optimization of building structures is one of the priority engineering tasks. Its relevance is determined by the expansion of the variety of internal structures of nonuniform structural elements, as well as the need to construct refined mathematical models considering nonlinear deformation factors.
Purpose: The aim is to the integral criterion for the least strain energy in relation to a nonuniform, nonlinearly deformed bar. The design diagram of the Timoshenko bar has a symmetrical structure and contains structural elements (layers) made of homogeneous nonlinear elastic materials.
Methodology: The material deformation is described by a polynomial approximation of an arbitrary order. Nonlinear dependencies are obtained for internal forces as functions of generalized strain of the axial line. Their coefficients are rigidity characteristics of higher orders.
Research findings: The suggested dependences used for strain energy components, are derived depending on deformation, curvature and average shear. Their use makes it possible to simplify formulation of optimization problems solved using the energy criterion with regard to physical non-linearity and nonuniformity of bars.
