ROAD PAVEMENT USING GEOSYNTHETICS ON THE TERRITORY OF RURAL SETTLEMENTS

Abstract

Quantitative and qualitative changes in recent years in the road industry require new technological approaches to road construction. Today some of the most used materials in road construction are geosynthetics. Geosynthetics have become interesting engineering materials in a wide range of applications and geotechnical, environmental, hydraulic, environmental, and private developments. The paper presents the research on the load and operational condition of the test model of a road reinforced with different geosynthetic materials. Geogrid and geotextile were used in testing. High-strength geotextiles or geogrids can provide adequate embankment reinforcement when properly designed and selected. Both materials can be used equally well, provided with the requisite design properties. Under the influence of the load from transport, the filler used for the cells is compacted. Currently, there is a redistribution of load throughout the entire volume of the monolithic structure with the grid. The tests carried out showed that using geotextiles leads to a decrease in the settlement coefficient by 25% and the use of a geogrid - by 38%. In rural areas of Kazakhstan, where the road network is in poor condition due to weak soils, strengthening the roadway with traditional materials will require large sums of money. Reinforcing the soil of unpaved roads with geosynthetic materials will allow more rationally and at a lower cost to improve the performance of unpaved roads in rural areas of Kazakhstan.
