The article presents the study results of a soil-like fraction contamination at a landfill located on the territory of the Traktorozavodsky district of Volgograd with heavy metals. The soil-like fraction's pollution level was assessed using a cumulative chemical pollution index (Zc) and its modifications. It was determined that the contamination levels with heavy metals are dependent on a used cumulative chemical pollution index modification. The use of the average geometric values of a cumulative chemical pollution index (Zc) is preferred for a pollution assessment of a soil-like fraction. Because the pollution level of a studied soil-like fraction was assessed as hazardous, its use as a recultivation material can only be permitted after a detoxification.The main pollutants in the soil-like fraction are cadmium, copper, and nickel.

Modern cinema demonstration technologies have changed the perception of the auditorium space. Multi-channel digital stereo demonstration, the use of mobile platforms for seating created conditions for the design of small-capacity auditoriums with a round plan shape. Wall enclosing structures in this case have the shape of the inner surface of the cylinder. Finishing with acoustic plates on the frame is time-consuming and does not always allow you to repeat the shape of the fence. The design of acoustic decoration of cinema halls with a round or oval shape of the plan is rationally carried out with the use of acoustic foam "Flexacoustic" on the walls and Soundec ceiling panels (Soundec). The most effective combination, providing uniform sound absorption in frequencies, was obtained by using acoustic foam rubber "Flexacoustic" with a density of 30 kg/m3 and wood panels "Soundek" with a density of 450 kg/m3 with internal filling plates "Acoustic Fiber". The study of the use of domestic materials that are convenient for finishing works and recommendations for the choice of rational use, different in properties of acoustic building systems, allowed us to obtain results that will ensure the best conditions of audibility in the cinema hall.

The introduction of construction work in urban development is associated with a number of important factors, as well as near unusual engineering and geological conditions. In this regard, design schemes were identified for the construction of new buildings erected in cramped urban areas. Thus, it was found that the most suitable structural scheme for various buildings is a frame with the implementation of certain structural changes in view of the cramped conditions. This also applies to the design scheme of the foundations. This paper discusses the main structural schemes, as well as schemes and their design changes to ensure the reliability of a public building being built in cramped conditions.

The development, development and reorganization of territories for civil construction projects is often associated with problems of control and protection against erosion processes. Territories previously considered inconvenient are now subject to intensive development. The investment attractiveness of such territories is very high, so it is necessary to carry out engineering preparation measures, including those to protect it from erosion processes. Studies show that the most environmentally friendly structures to prevent erosion processes are geocomposite systems created on the basis of anti-erosion geosynthetic materials. But before applying any measures to stabilize erosion processes, it is necessary to understand the process of interaction between the methods used and the surfaces to be protected. The article considers the zoning of coastal slopes, as the most vulnerable to the impact of erosion of territories in cities, on non-flooded, partially flooded and permanently flooded zones. Accordingly, this division was made in order to determine the possible impacts on the structures of geocomposite systems. Each impact (hydraulic, snow, ice) is described using mathematical modeling, indicating methods for calculating the stability of the geocomposite system for the zones identified in the study. It has been established that the strength of a geocomposite system also affects its stability, therefore, when determining the overall stability of a geocomposite system, the concept of its tensile strength is introduced. The presented materials are of great importance in practical application. This is due to the reduction of material and labor costs for the implementation of anti-erosion protection measures when applying the results of this study. Further research is aimed at optimizing the design of anti-erosion protection based on geocomposite systems in order to organize their mass production and create standard industrial designs.

The paper presents the results of research into the road polymer-modified asphalt (PMA) concrete, which is supposed to be used in the Siberian region, in particular, in the city of Krasnoyarsk and the Krasnoyarsk Territory. For the preparation of asphalt concrete, a polymer additive was used in the form of DST-30 grade thermoplastic elastomer. In addition, the results of studies using IR spectroscopic methods of the processes of interaction between bitumen and DST dissolved in industrial oil are presented. It has been established that the change in the physical properties of bitumen when DST is added to its composition is a consequence of chemical interaction in the studied composite binder. On the previously developed composition of the polymer bitumen binder, hot asphalt polymer concretes were prepared, which were studied for the main physical and mechanical indicators. The resulting compositions meet the regulatory requirements. When compared with the properties of asphalt concrete on "pure" bitumen, it was found that the introduction of a polymer additive leads to an increase in durability at 20 and 500C, water resistance and strength reduction at 00C, which indicates an increased crack resistance at a negative temperature of polymer-modified asphalt concrete compared to regular asphalt concrete. Recommendations on the factory technology for the preparation of asphalt concrete are given. The resulting compositions are proposed for industrial implementation by road maintenance bodies and firms in the city of Krasnoyarsk.
