Field evaluation of the geotechnical behavior of lime-ground cushions in the Republic of Tajikistan

The article presents the methodology for conducting field tests of lime-soil cushions to examine the technology of their construction, gain strength, their operation under rigid stamps, and the characteristics of stress-strain state development. The results of field studies showed that the lime-soil mixture can be used as a structural material in the preparation of bases on loess- loess soils in the conditions of the Republic of Tajikistan. Field tests showed that the lime-soil mixture achieved a dry density of 1.53-1.56 t/m 3 , while the deformation modulus increased by 5-10 times compared to natural loess soils.
