Abstract

Both the California Bearing Ratio (CBR) and the Modulus of Resilience (MR) are assessments that are widely used to measure the load-bearing capability and elastic behavior of subgrade soils, which are vital for the construction of infrastructure. Within the scope of this article, a complete investigation of the California Bearing Ratio (CBR) and moisture is presented.

Clay soils were subjected to ratio Modulus of Resilience (MR) tests, which were demonstrated through a case study of an urban road construction project in Dikirnis City. The purpose of this study is to investigate the link between CBR and MR values by analyzing the behavior of clayey subgrade materials under a variety of moisture conditions and levels of compaction. For the purpose of designing pavements and developing their long-term performance, the findings reveal that the moisture content of clay soils has a major impact on their performance. This provides vital insights for the design of pavements.
