The principle of modifying the soil LBS is an irreversible change in the physical and mechanical properties of the soil due to chemical action of an aqueous solution a modifier when making LBS in the ground. Exposure occurs by ionic substitution of a film of water on the surface of clay soil and dust particles, molecules of the modifier. As a result, the clay soil particles become smaller. Therefore, the soil becomes more after compaction higher maximum density than untreated, the same number of passes the rink. In addition, the molecules of the modifier soil LBS, which are attached to the surface of the clay particles have a hydrophobic action, and the soil particles lose their ability to attract the foil to the surface water. Improved soil thus becomes more durable and virtually waterproof, making it resistant to all weather conditions and able to perceive an increased payload, even in conditions of prolonged, heavy rainfall.

Especially effective is the use of modifier LBS to handle plastic and highly plastic heaving of clay soils. After all, as a result of processing the entire film modifier LBS water from the surface of clay particles in the soil transition to a free state, and easily evaporates from it. A degree of swelling and swelling soils decreases sharply. Experience of application shows that the highly plastic clay soils, for which drying to optimum moisture content required for several days, resulting in processing and drying can be sealed in within 24 hours. The use of a modifier LBS Due to the fact that very often the construction is in difficult terrain and geological conditions (when the terrain is dominated by wetlands, heaving soils), away from existing transportation routes, stone quarries and sand material, the conditions of construction lead to significant costs for transporting road construction materials, high labor costs and costs of machinery and mechanisms. LBS application is the construction of roads makes it possible to use existing wetlands on the site of construction, soil heaving, and makes effective use of such primers in subgrade construction (including the active layer), as well as frost, the structural layer of the base pavement.

Bearing capacity of soil, modified LBS, is 180 MPa. Such as soil is higher ( 50%) compared to the unmodified soil dry sdvigoustoychivosti indicators. Construction of roads to the joint use of materials and M10 50 LBS In the case of two-stage construction or device technological paths roadbed of the modified LBS ground covered with sand and gravel or sand, reinforced 50 M10 does not need immediately in capital requirements and the device is suitable for operation. Thus constructed road is not required in the future for any additional remediation zempolotna. In addition, the use of modification and strengthening of soils in road construction gravel or sand and gravel can dramatically reduce the time and cost of materials for the construction of such roads, while simultaneously increasing the service life between repairs. Thus, the processing modifier LBS allows you to: dramatically lower humidity clay soil in a very short period of time To increase the modulus of elasticity, strength properties and water resistance of clay soils sharply, at times reduce swelling and frost heave
