Has anyone come across abnormally high CBR values especially on cement stabilised soils? Here I have a soil sample mixed with 8% OPC that yields CBR of about 150. I don’t think standard literature ever talks on CBR on stabilised soils.
Also, the unconfined compressive strength of the stabilised material is also high to the order of 24 kg/cm2. Is there a relation which I can derive based on the CBR and UCS test results. Furthermore, some of the engineers related to pavement designs quote UCS values instead of CBR values which using the stabilised soils. Can someone please throw some light on this?
Any help on the matter shall deeply be appreciated.
