In-Situ CBR
Mechanical Loading Machine (California Bearing Ration) Hand Operated
The in-situ CBR mechanical loading
machine is used to perform CBR in-situ tests on road construction
which enables the bearing capacity of soils to be determined quickly
and efficiently for prompt results. Alternatively, the CBR in-situ
jack assembly can be mounted on a simple manual version of
conversion frame for measuring CBR values in the laboratory, As
having the advantage of being disassembled, it becomes available for
in-situ testing together with necessary components are incorporated
for such an usage. It is ideal for field testing because of its
portability advantages.
