Abstract

This project deals with Design of flexible pavement by exploitation California bearing ratio test take a look at for both soaked (wet soil) and unsoaked (dry soil). California Bearing Ratio (CBR) value is a very important parameter for design of flexible pavements. It may be used for determination of sub grade reaction of soil. It's one in all the foremost necessary engineering properties of soil for design of sub grade of roads. CBR value of soil may depends on many factors like optimum moisture content (OMC), maximum dry density (MDD), plastic limit (PL), liquid limit (LL), plasticity index (PI), permeability of soil, type of soil etc. The CBR value is also affected by unsoaked or soaked condition of soil. These tests are performed in the laboratory. The CBR may be done on the premise of those tests which are less time consuming and low cost, fast to perform, then it will be simple to induce the data concerning the subgrade strength over the length of roads. By considering this a number of engineers with in the past created their report during this field and designed completely different pavements by determinative the CBR value on the premise of results of less time consuming, simple to perform tests and low cost. In this study, the values of CBR of different soil samples and correlate their CBR values for the design purpose of flexible pavement as per guidelines of IRC: SP: 37-2001.
