Summary

Introduction. The article discusses the main methods of soil stabilization in road construction. A detailed analysis of the main methods of reinforcement is carried out from the point of view of engineering and geological conditions, economic efficiency, and durability. It is determined that the most optimal choice of technology will ensure an increase in the bearing capacity of the road base, a reduction in deformations, and an increase in the service life of the road surface.

Issues. In the context of martial law in Ukraine, the selection of sites for road infrastructure construction is becoming particularly important. The limited availability of suitable areas will force the use of sites with weak soils for road construction. To ensure the reliability and safety of road surfaces in such areas, special engineering solutions and technologies must be used to reinforce the layers of the road surface. This will allow for the effective use of available resources with unfavorable soil conditions, the rapid restoration of the road network, and the provision of the needs of the population and the military in emergency situations.

Objective. To analyze the main methods of soil reinforcement and select optimal reinforcement solutions to ensure the reliability and durability of road surfaces.

Conclusions. The methods of soil reinforcement and the selection of optimal solutions to improve the reliability of road pavement structures are one of the key tasks in road construction, as this guarantees the durability of motorways and the continuous operation of the transport network, reduces the need for frequent repairs and, accordingly, reduces road maintenance costs with limited funding for the road industry.
