Consolidation Test
Consolidation Test
(OP)
Hello everybody,
Does anybody have experience with consolidation test using constant rate of loading (CRL)? How comparable are the results to the regular testing methods.
I appreciate any advise on the required equipment as well.
Thanks

RE: Consolidation Test
What's your situation that you need to do something other than the standard 1-D oedometer test?

If you have access to ASTM D4186 V.04.09 please read. The biggest advantage to the CRS test compared to the incremental is speed. With a CRS test a sample can be completed in as little as two (2) days sometimes sooner. The biggest limiting factor is the permeability of the soil. YOU have to keep a pore pressure ratio between 3-15% according to ASTM. The biggest downfall is the cost of the equipment. ASTM D 4186 states that you must use data aquisiton software due and that type of automated equipment is not cheap. I hope this helps.

As rockiolgist mentioned the most attracting thing with CRS and CRL methods is their speed. Further, if you have triaxial machine with minimal additional cost you can run the CRS test.
My only problem is with the validity of the results and how comparable are they with the regular 1D test.
Thanks
