Prospects for Construction of Monolithic Cement-Concrete Transport Infrastructure Facilities in the Siberian Region

Today, one of the priority tasks of road construction in the Russian Federation is to improve road safety and increase the quality and service life of road surfaces. The climate of the Siberian Federal district, selected as a construction area, is characterized as sharply continental, with hot summers, harsh winters, and a sharp drop in daily temperatures. Therefore, improving the quality of road surfaces and their durability is an urgent problem both in the short and long term. In this paper, we analyzed the effectiveness of testing the technology of laying monolithic transport infrastructure objects using a concrete paver and their operation in the city of Krasnoyarsk. As the object of research, we selected road drainage trays made in 2015 using the Power Curber 5700-C concrete paver, located at a transport interchange near the village of Badalyk in the Krasnoyarsk territory. The results of the survey showed that the identified defects do not affect the operational suitability of the elements. However, when studying the possibilities of using cement concrete coatings in the city of Krasnoyarsk, it turned out that the issues of manufacturing technology and selection of concrete mix compositions taking into account local conditions were not sufficiently developed.
