Humboldt CBR/LBR Solutions
The California Bearing Ratio (CBR) Test was developed by The California State Highway Department and is widely used to determine the resistance strength of
subgrade and subbase materials. The test is basically a simple penetration test
using a load frame and a standard, compacted CBR test mold of the material
to be tested. The results of the test are then compared and evaluated to known
standards already established for the material being tested. Meets ASTM D1883；AASHTO T193; BS 1377 Part 4.
CBR Setup using the HM-3000.3F Load Frame
Pictured is the HM-3000.3F Load frame with a typical CBR setup. See the
chart below for items to order for the setup shown. See page 60 for more
information on the HM-3000.3F Load Frame.
Typical LBR Setup
For LBR setups, substitute H-4178F.4 for the H-4178 penetration
piston and HM-2300.100P for the HM-2300.100 S-type load cell.
