Correlation between CBR Values and Index Properties of

This paper presents the results of the correlation between California Bearing Ratio (CBR) and index properties of soils. Laboratory tests were carried out to determine soaked CBR, LL, PL, PI, MDD and OMC on soil samples collected from Ibiono, Oron and Onna L.G.A. in Akwa Ibom State. A correlation relationship between CBR and soil index properties were developed using non-linear and multiple

What is CBR Test in Civil CivilJungle

What is CBR Test. CBR Test Full Name is California Bearing Ratio (CBR) In the year 1930, this test was developed by the California Division of Highways around 1930 and was consequently accepted by several states, nations, the U.S. federal agencies, and worldwide.; As a result, in the US, most agency and commercial geotechnical laboratories are set to perform CBR tests.
