IOWA Bearing Value Apparatus : ZI3085
For determining the supporting strength of soil and aggregate mixtures which pass the 2mm and do not contain more than 10% sand size material.
The salient features of this apparatus are :-
1) The moulds used in this test are very small hence very smaller samples are required which is a great advantage when a large number of testes have to be carried out with a limited quality of soil available. Also when large quantities of soil are available fresh samples can be used for each test.
2) Time required this test is very much less than C.B.R. test and thus more number of tests can be carried out.
