Jul 22, 2010· AASHTO should clarify those figures a bit. Even though the figure shows a straight line correlation between the different test parameters, that is not so, particularly with respect to the resilient modulus vs. CBR. Secondly, if you have a base material with a CBR of 30, then you have a very poor base material (the basis of the correlations is for a base CBR=100).
