Abstrait:

This article deals with the design of the foundation of the subgrade of a motor road on a weak foundation (peat, sapropel) in difficult climatic and engineering-geological conditions. The features of physical and mechanical properties of soft soils imply the creation of non-typical design solutions using modern technologies and building materials. As a result, the theoretical studies of the processes of accelerated consolidation of weak soils were carried out and a design of the subgrade was proposed based on the use of electro-physical and filtration properties of various aggregates, namely the cathode layer (crushed stone from blast furnace coke or conductive coal), the drainage layer (sand) and the anode layer (crushed stone from dolomite limestone or basalt). The developed structure will allow reducing the consolidation time of a weak base and providing the necessary strength of the base by increasing shear resistance, which will increase the durability and reliability of the road, as well as reduce the technological construction time.
