In order to save cotton cellulose, which is valuable in the republic, experiments on obtaining a new type of multi-layered paper and cardboard by adding polyester (lavsan) fiber waste to its composition were carried out in the laboratory certification department of the Global Komsco Daewoo joint venture based on technological regulations. The physical and mechanical properties of the new type of paper obtained in the article are thoroughly studied. At the same time, the article shows the feasibility of using secondary synthetic fibers in the production of a new type of paper for the printing and paper industries.

The article presents the results of calculating the performance of tires. It is substantiated that in quarry operating conditions, the determination of the actual tonne-kilometers per hour (TKPH) is an important criterion for tire performance. Due to the fact that tire manufacturers (Michelin, Belshina, Goodyear, Bridgestone) give different correction factors (K1, K2) to calculate the actual TKPH, the following correction factors (K3) TKPH have been developed depending on the hardness of the rocks laid as surface of open pit roads: for JSC “Almalyk MMC” K3=1.15, for JSC “Kizilkumcement” K3=1 and for JSC “Uzbekugol” K3=0.8.

This article discusses the problems and shortcomings in the construction of modern houses in Tashkent. As a result, construction companies are cautious in favoring new materials or construction methods. Secondly, there is a high responsibility of builders for the final product, which is explained by the risk of unfortunate consequences, up to a threat to people’s lives, if inappropriate technologies are used or mistakes are made at the design stage. This is primarily due to the long service life of buildings and structures, during which unforeseen shortcomings of the technology used may appear.

This article discusses the problems of combining the unique structures of urban planning in Uzbekistan, built after the 60s of the twentieth century, with modern architecture. The study also examines the history of buildings and structures in Tashkent, as well as the fact that many buildings in the city fell into disrepair after the 1966 earthquake. There are also public buildings and residential buildings built between 1966 and 1996, thanks to which buildings built according to unique and inimitable projects have become the hallmark of the city.
