CORRELATION OF INDEX PROPERTIES WITH THE CBR …
CBR max = γ dmax-9.63 for fine grained soils 15 𝑘 /𝑚3 < 𝛾 𝑚𝑎 < 20 𝑘 /𝑚3 ---(5) CBR max = 2.95 γ dmax-9.08 for laterite soils 𝛾 CBR max = 17.44 γ dmax-276.76 for the crushed rocks 𝛾 where γ dmax is expressed in kN/m 3 They also reported that, CBR values can be correlated with maximum CBR values given by
