Mechanical properties of reinforced loess soils in road pavements

Abstract

The modern development of road construction promotes the tasks of not only increasing the strength of road structures, but also the need to effectively use local materials and soils in road construction. During the design and construction of highways, many road scientists of the world have carried out their scientific and research work on soil strengthening based on the road bed. Several methods and techniques have been developed for this. Also, developed countries are producing a lot of surfactants, modifiers and additives for soil strengthening. In this article, research work was carried out in laboratory conditions to study the mechanical properties of soil strengthened with the help of a modifier. Measurement, comparison, experimental laboratory, mathematical statistical analysis in the processing of test results, analytical methods specified in regulatory documents were used in the performance of research work. The results of the conducted laboratory research are specific to loess soils found in the conditions of Uzbekistan. The use of construction work on the foundation of the road bed from reinforced soil allows to reduce the volume of construction work, reduces the consumption of transported sand and gravel materials, and increases the service life of the road.
