| Description
| - California bearing ratio (CBR) test has been used for classification and analyses of soils in road subgrades and road construction materials around the world. One of the problematic moments in the CBR laboratory tests is the use of annular weights. During a CBR test a required number of annular weights, whose weight substitutes for the future road body, is placed around the penetration plunger and on a test specimen. The authors determined the inaccuracy between the weight of used annular weights and the standardized value when the annular weights should substitute the load stress that would be caused by a road body thickness of 700 mm. This contribution is focused on soil behavior while using different values for loading of samples by annular weights, whose purpose is to substitute weight of the road above the tested layer. The soils was tested both in its natural state, and also stabilized by the addition of hydraulic binder. Loading of a sample by one weight with the weight of 2 kg represents 60 -- 70 mm of a road body. Loading of a sample by one weight with the weight of 14 kg represents 400 -- 500 mm of a pavement. The results show that soil failure behavior during a CBR test is very different for treated and untreated soils. It was found that CBR results can differ by tens of percent when comparing tests with different weights of annular weights. When keeping to a standard assumption that annular weights substitute for the weight of the road above a tested layer, there is a significant decrease in CBR values. The stress on a CBR plunger often reaches ten-fold of future load by traffic, therefore use of the results, especially during determination of various correlations of CBR to other parameters, is very problematic.
