Rehabilitation and retrofitting of existing pavements justify the residual strength assessment to guide implementation of necessary life enhancement exercise and have necessarily become a primary task of the highway construction industry. Laboratory California Bearing Ratio (CBR) tests were performed at various moisture contents such as OMC-1%, OMC and OMC+1% (OMC = Optimum Moisture Content). The values of CBR are calculated with and without plunger side friction. The moisture content increases from OMC -1% to OMC, there is an increase in CBR and further increase of moisture content from OMC to OMC+1%, there is a decrease in CBR. The CBR estimated considering plunger friction showed about 0.32 to 2.72% increment as compared to the laboratory CBR estimated without considering plunger friction. Similarly The moisture content of samples varying from OMC-1% to OMC+1%, there is increase in UCS and cohesive strength up to OMC and from OMC onwards, there is decrease in Unconfined Compressive Strength (UCS) and undrained cohesive strength of the samples. Further, empirical relationships also established between the CBR and UCS.
