Development of a Technology for the Device of Structural Elements of Road Surfacing Made of Humus Soils Using the «Mador» Modifier

Statement of the problem. When performing road repair works using the technology of cold recycling, when installing foundations from reinforced soils or inert materials, in some cases there is a problem of getting humus clay soils into the structural layer of the pavement. Also, when solving special technical problems, such as the construction of temporary roads, the construction of roads for the passage of agricultural machinery during the spring thaw, there is a need to strengthen humus clay soils to ensure the movement of vehicles along the arranged layer. This circumstance led to the need to develop a technology for the device of a coating layer or a base made of humus soil using various inorganic binders, including in combination with the additive "MADOR", necessary to improve the physical and mechanical characteristics of the structural layers of pavement made of cement-reinforced materials. Results.The technology of work on the construction of a layer of pavement using humus clay soils is presented. The review of the results of physical and mechanical as well as physical and chemical studies of the effect of the modifier "MADOR" on the structure of clay humus soil reinforced with cement used for the construction of structural layers of pavement is presented. The results of studies of the structure of the grunt reinforced with cement together with the modifier "MADOR" are presented. Conclusions.The possibility of using the developed technology has been established and the positive effect of using the "MADOR" modifier to strengthen the humus clay soil has been predicted.
