A COMPREHENSIVE APPROACH TO IMPROVING THE DURABILITY OF SOIL CEMENT FOUNDATION
The use of effective materials in the construction of pavements is an urgent issue for the economy of our region and the country as a whole. This is especially true for regions in which there are no necessary road construction materials. Imported materials increase the cost of the object by several times, as their cost increases depending on the value of the distance of transportation to the construction site. One of the most frequently used materials is crushed stone, which despite its prevalence has a number of significant drawbacks. An alternative option as a material for the bases of pavements is soil treated with a mineral binder. The use of this material significantly reduces one-time construction costs. However, soil cement also has a number of disadvantages that do not allow its use in all regions of the country. One of the main disadvantages of soil cement is a low service life, which depends on the performance of water absorption, frost and crack resistance. This study is devoted to the issue of increasing the service life of soil cement foundation. Several ways to increase the service life by improving water absorption and crack resistance, due to the complex effect on the soil cement base are examined. Laboratory studies in this direction were conducted. Also in the study, the question of ensuring necessary quality of consolidation of the soil cement basis is considered. To solve this problem, constructive measures have been proposed to achieve a higher degree of consolidation. In conclusion, the cost calculation was carried out to confirm the economic efficiency of the proposed solution in base prices.
