DCP Test
DCP Test
(OP)
Hi, i completed a DCP test on a soil sample in situ, and have determined the penetration curve. Then determing the in situ CBR for each layer.
The question is what sort of conclusion could i draw from having CBR ranging from 13, 45 , 18 repectively for each layer going downwards?

At this point you can conclude that you have three equivalent CBR values. Now why do you need the CBR values? Are you designing a pavement? Are you doing a failure investigation of a pavement?
RE: DCP Test
What type of soil did you do the DCP test in - if soil with cohesion then the results should be read carefully. What length DCP did you use and did you visually observe the in-situ soil?
