The implementation of innovative solutions enables the construction of modern, reliable, and safe roads and bridges. Over the past nine years, the Federal Road Agency (Rosavtodor) alone has used the latest developments on more than 1,700 road projects, reported Deputy Prime Minister Marat Khusnullin.
"Scientific and technological development of the road industry, including the introduction of innovative technologies and materials, is of great importance in the face of unprecedented sanctions. Furthermore, this work is particularly relevant today, as the industry faces challenges such as increasing labor productivity, digitalization, developing artificial intelligence technologies, and shortening the investment and construction cycle. Such developments make it possible to predict the condition of road structures and utilize intelligent control systems and eco-friendly materials. Russian road workers, including Rosavtodor, have accumulated successful experience developing and implementing innovative solutions in the road industry. Since 2016, such technologies have been used at more than 1,700 sites across the country. Road workers have achieved a breakthrough in the industry and doubled the time between repairs for federal highway pavements," noted Marat Khusnullin.
For example, the use of modern technical solutions makes road structure research a high-tech process. An example of this approach is the accelerated testing using the TSIKLOS wheel load simulator, developed at the request of RosdorNII, a Federal Autonomous Institution under the Federal Road Agency (Rosavtodor).
The installation allows for a complete picture of the performance of pavement layers designed for long-term use to be obtained within two to four months, significantly accelerating the scientific evaluation of materials and design solutions. The simulator is capable of generating up to 50,000 load cycles per day, reproducing axle loads of up to 13 tons.
Over the course of a month, the four wheels of the rig can apply load to the test track approximately 1.5 million times. This high intensity allows specialists to simulate the accumulation of fatigue damage in road surfaces, monitor the development of deformations and cracks at each stage of operation, and identify the causes of structural failure.
Domestic developments also include modern binders and composite compounds for strengthening and stabilizing subgrade soils. The use of special additives and modifiers in asphalt concrete and cement concrete mixtures improves the performance properties of road surfaces, extending their service life and resistance to climate change.
Eco-friendly traffic management solutions play a vital role in the industry's development. The use of bollards, delineators, and curbs made from recycled rubber not only reduces waste but also improves road safety.
In addition, intelligent control systems are being introduced into the lighting system on federal highways under our jurisdiction, reducing energy consumption and extending the service life of the equipment.
Innovative materials are becoming increasingly important in bridge construction, such as vibrated asphalt concrete, which serves as both a highly effective roadway surface and waterproofs reinforced concrete structures, providing reliable moisture protection. One of the most promising materials is currently ultra-strong fiber-reinforced concrete: thanks to its unique structure, it offers exceptional strength, absolute water resistance, and frost resistance, extending the service life of bridges to 100–150 years and significantly reducing the weight of structures compared to traditional reinforced concrete.
To ensure the stability of large-span and off-grade bridges, Russia has developed the world's first national standard defining methods for confirming the aerodynamic stability of superstructures. This document is based on the results of numerous experimental studies and can serve as a model for global bridge construction practices.
